Page 15: Using Acu
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. Press the Enter key to accept the settings. Press the F8 key to confirm the settings and save the new configuration. After several seconds, the Configuration Saved screen appears. -

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: Highlight the controller. -

Page 21: Replacing A Battery
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. -
Page 22: Upgrading The Cache
Remove the battery pack from the server. Plug the cable into the new battery pack. Install the new battery pack into the server. 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. - Page 23 If the LED is not lit, disconnect the battery cable from the cache. NOTE: Your model might look different from the one illustrated. Remove the controller from the server, and place it on a firm, flat, nonconducting surface. Remove the existing cache from the controller, pulling at both ends of the cache module with equal force.

Online/Activity Fault/UID LED Interpretation LED (green) (amber/blue) The drive is online, but it is not active currently. Flashing regularly Amber, flashing Do not remove the drive. Removing a drive may (1 Hz) regularly (1 Hz) 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. -
Page 26: Effects Of A Hard Drive Failure
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. -
Page 27: Replacing Hard Drives
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. - Page 28 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.
-
Page 29: Upgrading Hard Drive Capacity
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. Restore data from backup. Writing data to the location of the unreadable sector often eliminates the error. -
Page 30: Moving Drives And Arrays
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. - Page 31 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.
