Question
A customer wants to change a production RAID Group from RAID 5 (7D+1P) to RAID 6 (6D + 2P) on a VSP G700 during normal operations. They have just unmapped the LUNs from the channel ports.
What needs to be performed next?
A. The RAID level must be changed in Storage Navigator.
B. The RAID level must be changed in the SVP Maintenance window.
C. The RAID 5 Group must be put into DRU mode in Storage Navigator.
D. The RAID Group must be deleted.
Answer
D. The RAID Group must be deleted.
Explanation
To change a RAID Group from RAID 5 (7D+1P) to RAID 6 (6D+2P) on a VSP G700 during normal operations, the existing RAID Group must be deleted after unmapping the LUNs from the channel ports. It is not possible to directly change the RAID level or configuration of an existing RAID Group.
After deleting the RAID Group, a new RAID Group with the desired RAID 6 configuration can be created using the available drives. The LUNs can then be recreated and remapped to the channel ports as needed.
