Fault Tolerant, Degraded, Missing Drive
The vdisk is online and fault tolerant, however,
some of the drives are down.
This is a degraded state and only applies to RAID
6. Use RAIDar to assign either a global spare or a
vdisk spare, and start the rebuild:
Select Manage > Virtual Disk Config > Global
Spare Menu.
Note : Reconstructing a RAID-6 virtual disk to a
fault-tolerant state requires two properly sized
spares to be available.
Critical
The vdisk is online, however, some drives are
down and the vdisk is not fault tolerant.
This is a degraded state and only applies to RAID
6. Use RAIDar to assign either a global spare or a
vdisk spare.
• Select Manage > Virtual Disk Config > Global
Spare Menu.
• Ad a new drive as a vdisk spare by selecting
Manage > Virtual Disk Config > Vdisk
Configuration > Add Vdisk Spares.
Quarantined
The vdisk is in a critical state and has been
quarantined because some drives are missing.
Wait for the missing drive to come online. If it
doesn’t, dequarantine the vdisk and assign a spare.
• To remove a virtual disk from quarantine, select
Manage > Utilities > Recovery Utilities > Vdisk
Quarantine.
• Ad a new drive as a vdisk spare by selecting
Manage > Virtual Disk Config > Vdisk
Configuration > Add Vdisk Spares.
