Resetting a RAID Controller Module

CAUTION:
is not available for I/O operations until the reset is complete. If a host is using
virtual disks owned by the RAID controller module being reset, the I/O directed to
the RAID controller module is rejected. Before resetting the RAID controller
module, ensure that a multipath driver is installed on all hosts using these virtual
disks. If a multipath driver is not installed, the virtual disks are not available.
Resetting a RAID controller module is the same as rebooting the RAID
controller module processors. To reset a RAID controller module, run the
following command:
reset controller [(0 | 1)]

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.
