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 may not use the new I/O path until the multi-path driver

reconfigures and recognizes the new path. This action usually takes less than 5

minutes.

Changing the RAID Level of a Disk Group

Use the Change RAID 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 may be slightly affected

during the operation. Keep these guidelines in mind when you 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 is displayed, 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 Select the Logical tab.
2 Select the disk group.
3 Select Disk Group Change RAID Level.
4 Select the RAID level (RAID level 0, RAID level 1, RAID level 5, or RAID

level 6). The currently selected option is designated with a dot.

5 Click Yes.

The RAID level operation begins.
