Enabling RAID Controller Module Data Transfer At times, a RAID controller module might become quiescent while running diagnostics. If this occurs, the RAID controller module might become unresponsive. To revive a RAID controller module, run the following command: enable controller [(0 | 1)] dataTransfer Resetting Battery Age NOTE: A smart battery module does not require the battery age to be reset. After replacing the batteries in the storage array, you must reset the age of the battery, either for an entire storage array or one battery in a specific RAID controller module. To reset the age to zero days, run the following command: reset storageArray batteryInstallDate [controller=(0 | 1)] Removing Persistent Reservations Persistent reservations preserve virtual disk registrations and prevent hosts, other than the host defined for the virtual disk, from accessing the virtual disk. You must remove persistent reservations before you perform the following changes to your configuration: • Change or delete logical unit number (LUN) mappings on a virtual disk holding a reservation. • Delete virtual disk groups or virtual disks that have any reservations. To determine which virtual disks have reservations, run the following command: show (allVirtualDisks | virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ... virtualDiskNameN]) reservations To clear persistent virtual disk reservations, run the following command: clear (allVirtualDisks | virtualDisk[virtualDiskName] | virtualDisks [virtualDiskName1" ... "virtualDiskNameN])reservations Synchronizing RAID Controller Module Clocks To synchronize the clocks on both RAID controller modules in a storage array with the host clock, run the following command: set storageArray time Locating Physical Disks At times, you might need to locate a specific physical disk. In very large storage array configurations, this can sometimes be awkward. If you need to locate a specific physical disk, turn on the indicator LED on the front of the physical disk. To turn on the indicator LED on a physical disk, run the following command: 81
