NOTE: You cannot use ORCA to configure one spare drive to be shared among several arrays. Only ACU enables you to configure shared spare drives. 3. Press the Enter key to accept the settings. 4. Press the F8 key to confirm the settings and save the new configuration. After several seconds, the Configuration Saved screen appears. 5. Press the Enter key to continue. You can now create another logical drive by repeating the previous steps.
3. Select the Controller Settings option below Controller Options. The Controller Settings screen appears. Drive rebuild Drive rebuild occurs after a physical drive fails and is replaced. Only logical drives that are configured with RAID 1+0, RAID 5, or RAID 6 (ADG) can be rebuilt. Priority settings To set the drive rebuild priority: 1. Highlight the controller. 2.
Migrating RAID level and stripe size online Using CPQONLIN, you can modify both the RAID level and stripe size of an existing logical drive while online. IMPORTANT: Be sure that the cache battery is connected and fully charged before beginning an array expansion, RAID level migration, or stripe size migration. To migrate a drive: 1. Select the drive setting option under the logical drive menu for the drive you intend to modify. 2.

4. Plug the other end of the battery cable into the connector on the cache module. NOTE: Your model might look different from the one illustrated. NOTE: After installing a battery pack, you might see a POST message during reboot indicating that the array accelerator (cache) is temporarily disabled. This 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.
5. Remove the battery pack from the server. 6. Plug the cable into the new battery pack. 7. Install the new battery pack into the server. 8. Verify that the other end of the cable is properly seated in the cache connector. NOTE: After installing a battery pack, you might see a POST message during reboot indicating that the array accelerator (cache) is temporarily disabled. This is normal, because the new battery pack is likely to have a low charge.
• If the LED is not lit, disconnect the battery cable from the cache. NOTE: Your model might look different from the one illustrated. 4. Remove the controller from the server, and place it on a firm, flat, nonconducting surface. 5. Remove the existing cache from the controller, pulling at both ends of the cache module with equal force. 6. Install the new cache on the controller. Press firmly above each connector to ensure good electrical contact.
Replacing, moving, or adding hard drives In this section Identifying the status of a hard drive ......................................................................................................... 24 Recognizing hard drive failure ................................................................................................................. 25 Replacing hard drives .............................................................................................................................
Online/Activity LED (green) Fault/UID LED (amber/blue) Interpretation On Off The drive is online, but it is not active currently. Flashing regularly (1 Hz) Amber, flashing regularly (1 Hz) Do not remove the drive. Removing a drive may terminate the current operation and cause data loss. The drive is part of an array that is undergoing capacity expansion or stripe migration, but a predictive failure alert has been received for this drive.
Effects of a hard drive failure When a hard 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 nonfault-tolerant (RAID 0) logical drives in the same array will also fail.
Replacing hard drives The most common reason for replacing a hard drive is that it has failed. However, another reason is to gradually increase the storage capacity of the entire system. 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 a second or two while the new drive is spinning up.
drive) and write it to the replacement drive. This process is called automatic data recovery, or rebuild. If fault tolerance is compromised, this data cannot be reconstructed and is likely to be permanently lost. 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 is then lost. In exceptional cases, however, failure of another drive need not lead to a fatal system error.
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.
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 about these procedures, refer to the HP Array Configuration Utility User Guide. Moving drives and arrays You can move drives to other ID positions on the same array controller.
physical drives in the array. During this procedure, the logical drives each keep the same fault-tolerance method in the enlarged array that they 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 enlarge one of the original logical drives. This latter process is called logical drive capacity extension and is also carried out using ACU.
Diagnosing array problems In this section Controller board runtime LEDs.................................................................................................................. 32 Battery pack LEDs................................................................................................................................... 33 Diagnostic tools .....................................................................................................................................
Controller CPU activity level Item 7 status Item 8 status 0–25% Off Blinking 25–50% Blinking Off 50–75% On steadily Off 75–100% On steadily On steadily Battery pack LEDs Item ID Color Description 1 Green System Power LED. This LED glows steadily when the system is powered up and 12 V system power is available. This power supply is used to maintain the battery charge and provide supplementary power to the cache microcontroller. 2 Green Auxiliary Power LED.
LED3 pattern LED4 pattern Interpretation -- One blink every two seconds The system is powered down, and the cache contains data that has not yet been written to the drives. Restore system power as soon as possible to prevent data loss. Data preservation time is extended any time that 3.3 V auxiliary power is available, as indicated by LED 2. In the absence of auxiliary power, battery power alone preserves the data. A fullycharged battery can normally preserve data for at least two days.
