Once you have enabled both media scan and consistency check, use the check virtualDisk consistency
command to write the results to a file (specified by the mediaErrorFile and consistencyErrorFile
parameters):
check virtualDisk [virtualDiskName] consistency
[consistencyErrorFile=filename]
[mediaErrorFile=filename]
Resetting A RAID Controller Module
CAUTION: When you reset a RAID controller module, the RAID controller module 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.
To determine which virtual disks have reservations, run the following command:
show (allVirtualDisks | virtualDisk
[virtualDiskName] | virtualDisks [virtualDiskName1
... virtualDiskNameN]) reservations
