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:
