Managing Volumes

The LSI Storage Authority application lets you perform various operations on the volumes.

The firmware supports the following volume states on the controller:

• Optimal – A volume whose members are all online.

• Partially Degraded – A volume with a redundant RAID level that can sustain one or more member disk failure. This state also applies to the volume’s member drives. Currently, a RAID 6 or RAID 60 volume is the only volume that can be Partially Degraded.

• Degraded – A volume with a redundant RAID level with one or more member failures and can no longer sustain a subsequent drive failure (with exception in PRL-11).
• Offline – A volume with one or more member disk failures and data is no longer available (corresponds to DDF Failed state).
