dSelect the RAID controller module.

CAUTION: Possible loss of data access – If you do not use a multi-path driver, shut down any host applications that are currently using the virtual disk. This action prevents application errors when the I/O path changes.

eClick Yes.

The ownership of the virtual disk is changed. I/O to the virtual disk is now directed through this I/O path. You are finished with this procedure.

NOTE: The virtual disk might not use the new I/O path until the multi-path driver reconfigures and recognizes the new path. This action usually takes less than five minutes.

3To change the RAID controller module ownership of a disk group, perform these steps:

a Select the Logical tab. b Select the disk group.

c Select Disk GroupChangeOwnership/Preferred Path. Alternatively, you can right-click the disk group and select ChangeOwnership/Preferred Path from the pop-up menu.

d Select the RAID controller module.

CAUTION: Possible loss of data access– Changing ownership at the disk group level causes every virtual disk in that disk group to transfer to the other RAID controller module and use the new I/O path. If you do not want to set every virtual disk to the new path, change ownership at the virtual disk level instead.

e Click Yes.

The ownership of the disk group is changed. I/O to the disk group is now directed through this I/O path. You are finished with this procedure.

NOTE: The disk group might not use the new I/O path until the multi-path driver reconfigures and recognizes the new path. This action usually takes less than five minutes.

Changing the RAID Level of a Disk Group

Use the ChangeRAID Level option to change the RAID level on a selected disk group. Using this option changes the RAID levels of every virtual disk that comprises the disk group. Performance might be slightly affected during the operation.
