You can now reattach up to 277 hard drives and boot your server to run the SLES 11 SP2 operating system.

Battery pack service life

The batteries in BBWC battery packs are a consumable material. After 3 years of service, batteries may not provide predictable data retention times. If a battery fails completely, the HP Smart Array controller detects this condition and automatically restricts write cache functions to protect user data. To help ensure uninterrupted performance levels, HP recommends replacing battery packs at 3-year intervals.

In NiMH batteries, the charging and discharging processes create and recombine inert gases, which can cause the button cell to swell in size by as much as 20%. Battery packs are designed to stop charging before excess swelling occurs.

However, if excess swelling does occur, a pressure mechanism within the button cell releases these non-toxic, non-corrosive gases before the cell incurs physical damage. If this pressure release occurs, the battery no longer charges properly, and the storage solution reports a failed battery.

Specifications 36

Configuration tools

Option ROM Configuration for Arrays

Before installing an operating system, you can use the ORCA utility to create the first logical drive, assign RAID levels, and establish online spare configurations.

The utility also provides support for the following functions:

???Reconfiguring one or more logical drives

???Viewing the current logical drive configuration

???Deleting a logical drive configuration

???Setting the controller to be the boot controller

???Selecting the boot volume

If you do not use the utility, ORCA will default to the standard configuration.

For more information regarding the default configurations that ORCA uses, see the HP ROM-Based Setup Utility User Guide on the Documentation CD or the HP website (http://www.hp.com/go/ilomgmtengine/docs ).

Setting a controller as the boot controller

Use the following procedure to set a controller as the boot controller. To adjust the boot order settings for other controllers in the system, use RBSU ("Setting the controller order" on page 44 ).

1.Confirm that the controller is connected to a logical drive. (If it is not, it cannot be set as the boot controller.)

2.Perform a normal system shutdown.

3.Restart the server.

POST runs, and all controllers in the server are initialized one at a time in the current boot order sequence. If a controller is connected to one or more drives, an ORCA prompt message appears during the initialization process for that controller.

Installation and configuration 43

As soon as you see the ORCA prompt for the controller that you want to set as the boot controller, continue with the next step.

4.Press the F8 key.

The ORCA main menu appears. If the controller is configured with a logical drive, one of the menu options is to set the controller as the boot controller.

5.Select the appropriate menu option, and follow any subsequent on-screen instructions. If prompted to save the settings, do so.

6.(Optional) To configure or reconfigure an array on this controller, you can use ORCA. For more information, see the Configuring Arrays on HP Smart Array Controllers Reference Guide. This guide is available on the Documentation CD that is provided in the controller kit.

To configure an array at a later time or to use a different utility to configure the array, exit ORCA, and then restart the server for the new boot controller setting to take effect.

ROM-Based Setup Utility

RBSU is a ROM-based configuration utility that allows you to modify server configuration settings. RBSU is machine-specific and customized for each type of server. RBSU facilitates a wide range of configuration functions, including displaying system information, selecting the operating system, and configuring system devices and options.

If RBSU is supported by the server, access the utility by pressing the F9 key when prompted during the boot process. Refer to the HP ROM-Based Setup Utility User Guide or to the server documentation.

Setting the controller order

1.Power up the server.

The server runs the POST sequence and briefly displays an RBSU prompt.

2.At the prompt, press the F9 key to start RBSU.

3.Follow the on-screen instructions to set the boot order for the different controllers in the system.

4.Save the settings.

5.Exit from the utility.

For more information about using RBSU, refer to the HP ROM-Based Setup Utility User Guide or the server setup and installation guide. These documents are both available on the Documentation CD supplied in the server kit.

Array configuration tools

To configure an array on an HP Smart Array controller, three utilities are available:

???HP Array Configuration Utility (ACU)???An advanced utility that enables you to perform many complex configuration tasks

???Option ROM Configuration for Arrays (ORCA)???A simple utility used mainly to configure the first logical drive in a new server before the operating system is loaded

???HP Online Array Configuration Utility for NetWare (CPQONLIN)???A customized version of ACU for online configuration of servers that use Novell NetWare

Installation and configuration 44

For more information about the features of these utilities and for instructions for using the utilities, see the

Configuring Arrays on HP Smart Array Controllers Reference Guide. This guide is available on the Documentation CD that is provided in the controller kit.

Whichever utility you use, remember the following factors when you build an array:

???All drives grouped in a logical drive must be of the same type (for example, either all SAS or all SATA and either all hard drives or all solid state drives).

???For the most efficient use of drive space, all drives within an array should have approximately the same capacity. Each configuration utility treats every physical drive in an array as if it has the same capacity as the smallest drive in the array. Any excess capacity of a particular drive cannot be used in the array and so is unavailable for data storage.

???The more physical drives that there are in an array, the greater the probability that the array will experience a drive failure during any given period.

???To guard against the data loss that occurs when a drive fails, configure all logical drives in an array with a suitable fault-tolerance (RAID) method.

System maintenance tools

Updating firmware

Firmware update methods changed with the introduction of the ProLiant Gen8 servers. Use the appropriate information to locate and install firmware updates.

Installing an E500 or P400 cache battery

If you are replacing an existing E500 or P400 cache battery (instead of installing a battery where one did not exist), use the replacement procedure ("Replacing an E500 or P400 cache battery" on page 54 ) instead of this installation procedure.

WARNING: There is a risk of explosion, fire, or personal injury if the battery pack is not properly handled. Refer to "Battery replacement notice (on page 93)" before installing or removing any item that contains a battery pack.

1.Close all applications, and then power down the server.

Upgrade and replacement procedures 53

2.Plug the battery cable (supplied in the battery pack kit) into the battery pack.

3.Install the new battery pack into the server. (The installation site depends on the server. For further information, refer to the server-specific user guide.)

4.Plug the other end of the battery cable into the connector on the cache module.

After installing a battery pack, you might see a POST message during reboot indicating that the array accelerator (cache) is temporarily disabled. This behavior is normal because the new battery pack is likely to have a low charge. You do not need to take any action because the recharge process begins automatically when the battery pack is installed. The controller operates properly while the battery pack is recharging, although the performance advantage of the array accelerator is absent. When the battery pack has been charged to a predetermined level, the array accelerator is automatically enabled.

Recognizing drive failure

If any of the following occurs, the drive has failed:

???The fault LED illuminates.

???When failed drives are located inside the server or storage system and the drive LEDs are not visible, the amber LED on the front of the server or storage system illuminates. This LED also illuminates when other problems occur such as when a fan fails, a redundant power supply fails, or the system overheats.

???A POST message lists failed drives when the system is restarted, as long as the controller detects at least one functional drive.

???ACU represents failed drives with a distinctive icon.

???HP Systems Insight Manager can detect failed drives remotely across a network. For more information about HP Systems Insight Manager, see the documentation on the Management CD.

???The HP System Management Homepage (SMH) indicates that a drive has failed.

???The Event Notification Service posts an event to the server IML and the Microsoft?? Windows?? system event log.

???ADU lists all failed drives.

For additional information about diagnosing drive problems, see the HP Servers Troubleshooting Guide.

CAUTION: Sometimes, a drive that has previously been failed by the controller may seem to be operational after the system is power-cycled or (for a hot-pluggable drive) after the drive has been removed and reinserted. However, continued use of such marginal drives may eventually result in data loss. Replace the marginal drive as soon as possible.

Effects of a drive failure

When a drive fails, all logical drives that are in the same array are affected. Each logical drive in an array might be using a different fault-tolerance method, so each logical drive can be affected differently.

???RAID 0 configurations cannot tolerate drive failure. If any physical drive in the array fails, all RAID 0 logical drives in the same array also fail.

???RAID 1+0 configurations can tolerate multiple drive failures if no failed drives are mirrored to one another.

???RAID 5 configurations can tolerate one drive failure.

???RAID 50 configurations can tolerate one failed drive in each parity group.

Drive procedures 81

???RAID 6 configurations can tolerate two failed drives at a given time.

???RAID 60 configurations can tolerate two failed drives in each parity group.

???RAID 1 (ADM) and RAID 10 (ADM) configurations can tolerate multiple drive failures if no more than two drives, mirrored to one another, fail.

Compromised fault tolerance

CAUTION: When fault tolerance is compromised, data loss can occur. However, it may be possible to recover the data. For more information, see "Recovering from compromised fault tolerance (on page 82 )."

If more drives fail than the fault-tolerance method can manage, fault tolerance is compromised, and the logical drive fails. If this failure occurs, the operating system rejects all requests and indicates unrecoverable errors.

For example, fault tolerance might occur when a drive in an array fails while another drive in the array is being rebuilt.

Compromised fault tolerance can also be caused by problems unrelated to drives. In such cases, replacing the physical drives is not required.

Recovering from compromised fault tolerance

If fault tolerance is compromised, inserting replacement drives does not improve the condition of the logical volume. Instead, if the screen displays unrecoverable error messages, perform the following procedure to recover data:

1.Power down the entire system, and then power it back up. In some cases, a marginal drive will work again for long enough to enable you to make copies of important files.

If a 1779 POST message is displayed, press the F2 key to re-enable the logical volumes. Remember that data loss has probably occurred and any data on the logical volume is suspect.

2.Make copies of important data, if possible.

3.Replace any failed drives.

4.After you have replaced the failed drives, fault tolerance may again be compromised. If so, cycle the power again. If the 1779 POST message is displayed:

a.Press the F2 key to re-enable the logical drives.

b.Recreate the partitions.

c.Restore all data from backup.

To minimize the risk of data loss that is caused by compromised fault tolerance, make frequent backups of all logical volumes.

Replacing drives

The most common reason for replacing a drive is that it has failed. However, another reason is to gradually increase the storage capacity of the entire system ("Upgrading drive capacity" on page 86 ).

Drive procedures 82

If you insert a hot-pluggable drive into a drive bay while the system power is on, all disk activity in the array pauses for 1 or 2 seconds while the new drive is initializing. When the drive is ready, data recovery to the replacement drive begins automatically if the array is in a fault-tolerant configuration.

If you replace a drive belonging to a fault-tolerant configuration while the system power is off, a POST message appears when the system is next powered up. This message prompts you to press the F1 key to start automatic data recovery. If you do not enable automatic data recovery, the logical volume remains in a ready-to-recover condition and the same POST message appears whenever the system is restarted.

Before replacing drives

???Open Systems Insight Manager, and inspect the Error Counter window for each physical drive in the same array to confirm that no other drives have any errors. For more information, see the Systems Insight Manager documentation on the Management CD.

???Be sure that the array has a current, valid backup.

???Confirm that the replacement drive is of the same type as the degraded drive (either SAS or SATA and either hard drive or solid state drive).

???Use replacement drives that have a capacity equal to or larger than the capacity of the smallest drive in the array. The controller immediately fails drives that have insufficient capacity.

In systems that use external data storage, be sure that the server is the first unit to be powered down and the last unit to be powered up. Taking this precaution ensures that the system does not, erroneously, mark the drives as failed when the server is powered up.

In some situations, you can replace more than one drive at a time without data loss. For example:

???In RAID 1+0 configurations, drives are mirrored in pairs. You can replace several drives simultaneously if they are not mirrored to other removed or failed drives.

???In RAID 50 configurations, drives are arranged in parity groups. You can replace several drives simultaneously, if the drives belong to different parity groups. If two drives belong to the same parity group, replace those drives one at a time.

???In RAID 6 configurations, you can replace any two drives simultaneously.

???In RAID 60 configurations, drives are arranged in parity groups. You can replace several drives simultaneously, if no more than two of the drives being replaced belong to the same parity group.

To remove more drives from an array than the fault tolerance method can support, follow the previous guidelines for removing several drives simultaneously, and then wait until rebuild is complete (as indicated by the drive LEDs) before removing additional drives.

However, if fault tolerance has been compromised, and you must replace more drives than the fault tolerance method can support, delay drive replacement until after you attempt to recover the data (refer to "Recovering from compromised fault tolerance" on page 82 ).

Automatic data recovery (rebuild)

When you replace a drive in an array, the controller uses the fault-tolerance information on the remaining drives in the array to reconstruct the missing data (the data that was originally on the replaced drive) and then write the data to the replacement drive. This process is called automatic data recovery or rebuild. If fault tolerance is compromised, the controller cannot reconstruct the data, and the data is likely lost permanently.

Drive procedures 83

If another drive in the array fails while fault tolerance is unavailable during rebuild, a fatal system error can occur, and all data on the array can be lost. However, failure of another drive does not always lead to a fatal system error in the following exceptional cases:

???Failure after activation of a spare drive

???Failure of a drive that is not mirrored to any other failed drives (in a RAID 1+0 configuration)

???Failure of a second drive in a RAID 50 or RAID 60 configuration if the two failed drives are in different parity groups

???Failure of a second drive in a RAID 6 configuration

Time required for a rebuild

The time required for a rebuild varies, depending on several factors:

???The priority that the rebuild is given over normal I/O operations (you can change the priority setting by using ACU)

???The amount of I/O activity during the rebuild operation

???The average bandwidth capability (MBps) of the drives

???The availability of drive cache

???The brand, model, and age of the drives

???The amount of unused capacity on the drives

???For RAID 5, RAID 50, RAID 6, and RAID 60, the number of drives in the array

???The stripe size of the logical volume

CAUTION: Because data rebuild time ranges from 200 to 520 GB/h, the system could be unprotected against drive failure for an extended period during data recovery or a drive capacity upgrade. When possible, perform rebuild operations only during periods of minimal system activity.

When automatic data recovery has finished, the replacement drive LED behavior changes:

???For legacy drives, the Online/Activity LED changes from flashing steadily (1 Hz) to one of the following states:

o On???The drive is inactive.

o Flashing irregularly???The drive is active.

If the Online/Activity LED on the replacement drive does not illuminate while the corresponding LEDs on other drives in the array are active, the rebuild process has terminated abnormally. The amber Fault LED of one or more drives might also be illuminated.

???For HP SmartDrives, the Drive status LED changes from flashing green to solid green.

If the Drive Status LED on the replacement drive changes to flashing or solid amber, the rebuild process has terminated abnormally.

If an abnormal termination of a rebuild occurs, identify the cause and appropriate corrective steps in "Abnormal termination of a rebuild (on page 85 )."

Drive procedures 84

Abnormal termination of a rebuild

If the activity LED on the replacement drive permanently ceases to be illuminated even while other drives in the array are active, the rebuild process has terminated abnormally. The following table indicates the three possible causes of abnormal termination of a rebuild.

Each of these situations requires a different remedial action.

Case 1: An uncorrectable read error has occurred.

1.Back up as much data as possible from the logical drive.

CAUTION: Do not remove the drive that has the media error. Doing so causes the logical drive to fail.

2.Restore data from backup. Writing data to the location of the unreadable sector often eliminates the error.

3.Remove and reinsert the replacement drive. This action restarts the rebuild process.

If the rebuild process still terminates abnormally:

1.Delete and recreate the logical drive.

2.Restore data from backup.

Case 2: The replacement drive has failed.

Verify that the replacement drive is of the correct capacity and is a supported model. If these factors are not the cause of the problem, use a different drive as the replacement.

Case 3: Another drive in the array has failed.

A drive that has recently failed can sometimes be made temporarily operational again by cycling the server power.

1.Power down the server.

2.Remove the replacement physical drive (the one undergoing a rebuild), and reinstall the drive that it is replacing.

3.Power up the server.

If the newly failed drive seems to be operational again:

1.Back up any unsaved data.

2.Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. The rebuild process automatically restarts.

3.When the rebuild process has finished, replace the newly failed drive.

However, if the newly failed drive has not recovered:

1.Remove the drive that was originally to be replaced, and reinsert the replacement physical drive.

2.Replace the newly failed drive.

Drive procedures 85

3.Restore data from backup.

Upgrading drive capacity

You can increase the storage capacity on a system, even if there are no available drive bays, by swapping drives one at a time for higher capacity drives. This method is viable as long as a fault-tolerance method is running.

To upgrade drive capacity:

1.Back up all data.

2.Replace any drive. The data on the new drive is re-created from redundant information on the remaining drives.

CAUTION: Do not replace any other drive until data rebuild on this drive is complete.

When data rebuild on the new drive is complete, LED behavior changes:

oFor legacy drives, the Online/Activity LED changes from flashing steadily (1 Hz) to one of the following states:

???On???The drive is inactive.

???Flashing irregularly???The drive is active.

o For HP SmartDrives, the Drive status LED changes from flashing green to solid green.

3.Repeat the previous step for the other drives in the array, one at a time.

When you have replaced all drives, you can use the extra capacity to either create new logical drives or extend existing logical drives. For more information, see the Configuring Arrays on HP Smart Array Controllers Reference Guide on the HP website (http://www.hp.com/support/CASAC_RG_en ).

Moving drives and arrays

You can move drives to other ID positions on the same array controller. You can also move a complete array from one controller to another, even if the controllers are on different servers.

Before moving drives, you must meet the following conditions:

???If moving the drives to a different server, be sure the new server has enough empty bays to accommodate all the drives simultaneously.

???The array does not have failed or missing drives.

???No spare drive in the array is acting as a replacement for a failed drive.

???The controller is not performing capacity expansion, capacity extension, or RAID or stripe size migration.

???The controller is using the latest firmware version.

???The server is powered down.

Drive procedures 86

Before you move an array to another controller, you must meet the following conditions:

CAUTION: If the number of physical or logical drives exceeds the limit for the controller model and firmware version, then the controller may recognize an unpredictable subset of the drives, possibly resulting in failed arrays and data loss.

???If the other controller is connected already to one or more arrays of configured logical drives, the total number of logical drives on the controller after the drives have been moved must not exceed the number of logical drives that the controller supports. This number depends on the controller model and on the controller firmware version.

???The total number of physical drives on the other controller after the drives have been moved must not exceed the maximum number of supported physical drives for that controller model and firmware version.

???All drives in the array must be moved at the same time.

When all the conditions have been met, move the drives:

1.Back up all data before removing any drives or changing configuration. This step is required if you are moving data-containing drives from a controller that does not have a cache module.

2.Power down the system.

3.Move the drives.

4.Power up the system.

5.Observe the POST messages:

oIf a 1785 POST message appears, the drive array did not configure properly. Continue with step 6.

oIf a 1724 or 1727 POST message appears, drive positions were changed successfully and the configuration was updated. Continue with step 7.

6.If the array did not configure properly, do the following:

a.Power down the system immediately to prevent data loss.

b.Return the drives to their original locations.

c.Restore the data from backup, if necessary.

7.Verify the new drive configuration by running ORCA or ACU ("Configuration tools" on page 43 ).

Adding drives

You can add drives to a system at any time, if you do not exceed the maximum number of drives that the controller supports. You can then either build a new array from the added drives or use the extra storage capacity to expand the capacity of an existing array.

If the drives that you intend to add to the system are already configured into logical drives, you must meet certain conditions before adding drives to the system. For more information, see "Moving drives and arrays (on page 86 )." When you have successfully added the drives, reset the server so that the controller can recognize the logical drives.

To perform an array capacity expansion, use ACU. If the system uses hot-pluggable drives and ACU runs in the same environment as the normal server applications, you can expand array capacity without shutting down the operating system. For more information, see the Configuring Arrays on HP Smart Array Controllers Reference Guide on the HP website (http://www.hp.com/support/CASAC_RG_en ).

Drive procedures 87

The expansion process is illustrated in the following figure, in which the original array (containing data) is shown with a dashed border, and the newly added drives (containing no data) are shown unshaded. The array controller adds the new drives to the array and redistributes the original logical drives over the enlarged array one logical drive at a time. This process liberates some storage capacity on each physical drive in the array. Each logical drive keeps the same fault-tolerance method in the enlarged array that it had in the smaller array.

When the expansion process has finished, you can use the liberated storage capacity on the enlarged array to create new logical drives. Alternatively, you can use ACU to enlarge (extend) one of the original logical drives.

Electrostatic discharge

Preventing electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage:

???Avoid hand contact by transporting and storing products in static-safe containers.

???Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

???Place parts on a grounded surface before removing them from their containers.

???Avoid touching pins, leads, or circuitry.

???Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

???Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ??10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

???Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.

???Use conductive field service tools.

???Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an authorized reseller.

Regulatory compliance notices

Federal Communications Commission notice

Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules. These rules place computers and related peripheral devices into two classes, A and B, depending upon their intended installation. Class A devices are those that may reasonably be expected to be installed in a business or commercial environment. Class B devices are those that may reasonably be expected to be installed in a residential environment (for example, personal computers). The FCC requires devices in both classes to bear a label indicating the interference potential of the device as well as additional operating instructions for the user.

FCC rating label

The FCC rating label on the device shows the classification (A or B) of the equipment. Class B devices have an FCC logo or ID on the label. Class A devices do not have an FCC logo or ID on the label. After you determine the class of the device, refer to the corresponding statement.

FCC Notice, Class A Equipment

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at personal expense.

FCC Notice, Class B Equipment

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

???Reorient or relocate the receiving antenna.

???Increase the separation between the equipment and receiver.
