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 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. To change the RAID level of a disk group: 1 In the AMW, select the Logical tab and select a disk group. 2 Select Disk Group Change RAID Level. 3 Select the appropriate RAID level and click Yes to confirm the selection. The RAID level operation begins. Configuration: Disk Groups and Virtual Disks 131
