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.

minutes.

Changing the RAID Level of a Disk Group

Changing the RAID level of a disk group changes the RAID levels of every
virtual disk that comprises the disk group. Performance might be slightly
affected during the operation.
Guidelines to change the RAID level of a disk group:
• You cannot cancel this operation after it begins.
• The disk group must be in Optimal status before you can perform this
operation.
• Your data remains available during this operation.
• If you do not have enough capacity in the disk group to convert to the new
RAID level, an error message appears, and the operation does not
continue. If you have unassigned physical disks, use the Disk Group>>
Add Free Capacity (Physical Disks) option to add additional capacity to
the disk group. Then retry the operation.

1 In the AMW, select the Logical tab and select a disk group.
