Using the Snapshot Feature
• Map the snapshot virtual disk and make it accessible to any host on a
storage area network. You can make snapshot data available to secondary
hosts for read and write access by mapping the snapshot to the hosts.
• Create up to four snapshots per virtual disk.
NOTE:
The maximum number of snapshot virtual disks is one-half of the total
number of virtual disks supported by the RAID controller module.
• Increase the capacity of a snapshot virtual disk.
