6.5.8 Rescue Raid Set
When the system is powered off in the RAID set update/creation
period, the configuration possibly could disappear due to this ab -
normal condition. The “RESCUE” function can recover the missing
RAID set information. The RAID controller uses the time as the
RAID set signature. The RAID set may have different time after
the RAID set is recovered. The “SIGANT” function can regenerate
the signature for the RAID set.
Note:
Please contact us to make sure if you need to use rescue
function. Improperly usage may cause configuration
corruption.
6.6 Volume Set Functions
A volume set is seen by the host system as a single logical device.
It is organized in a RAID level with one or more physical disks.
RAID level refers to the level of data performance and protection of
a volume set. A volume set capacity can consume all or a portion
of the disk capacity available in a RAID set. Multiple volume sets
can exist on a group of disks in a RAID set. Additional volume sets
created in a specified RAID set will reside on all the physical disks
in the RAID set. Thus each volume set on the RAID set will have its
data spread evenly across all the disks in the RAID set.
The following is the volume set features for the 6Gb/s SAS RAID
controller.
