Dell 38XX, 34XX Resetting a RAID Controller Module, Enabling RAID Controller Module Data Transfer

RAID 0 virtual	No redundancy exists.
disks	NOTE: Do not run consistency checking commands on RAID 0 virtual disks.

Before attempting a consistency check, you must enable consistency checking using the set virtualDisk command. Use the following command to set the consistencyCheckEnabled parameter to TRUE:

set (allVirtualDisks virtualDisk

[virtualDiskName] virtualDisks [virtualDiskName1

... virtualDiskNameN] virtualDisk <wwid> consistencyCheckEnabled=TRUE

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:
