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 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 might 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 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 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. Configuration: Disk Groups and Virtual Disks 135
