6.7 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.

6.6.6 Delete Hot Spare

Select the target Hot Spare disk to delete by clicking on the ap-

propriate check box.

Tick on the Conﬁrm The Operation, and click on the Submit but-

ton in the screen to delete the hot spares.

6.6.7 Rescue Raid Set

When the system is power off in the Raidset update period, it may

be disappeared in this abnormal condition. The “RESCUE” func-

tion can recover the missing RaidSet information.

The RAID controller uses the time as the RaidSet signature. The

RaidSet may have different time after the RaidSet is recovered.

The “SIGANT” function can regenerate the signature for the

RaidSet.
