Related Disk Groups table
When you select a pool in the pools table, the disk groups for it appear in the Related Disk Groups table.
For selected pools, the Related Disk Groups table shows the following information:
Table 12. Disk Groups table
Field Description
Name Shows the name of the disk group.
Health Shows the health of the disk group: OK, Degraded, Fault, N/A, or Unknown.
Pool Shows the name of the pool to which the disk group belongs.
RAID Shows the RAID level for the disk group.
Class Shows the storage type for the disk group:
• Virtual (includes read-cache disk groups)
• Linear
Disk Description Shows the disk type. For virtual disk groups, the disk group's tier appears in parentheses after its disk type.
For read-cache disk groups, Read Cache appears in parentheses after the disk type.
Size Shows the storage capacity defined for the disk group when it was created.
Free Shows the available storage capacity for the disk group.
Current Job Shows the following current system operations for the disk group, if any are occurring:
• DRSC – A disk is being scrubbed.
• EXPD – The linear disk group is being expanded.
• INIT – The disk group is being initialized.
• RBAL – The ADAPT disk group is being rebalanced.
• RCON – At least one disk in the disk group is being reconstructed.
• VDRAIN – The disk group is being removed and its data is being drained to another disk group.
• VPREP – The virtual disk group is being prepared for use in a virtual pool.
• VRECV – The virtual disk group is being recovered to restore its membership in the virtual pool.
• VREMV – The virtual disk group and its data are being removed.
• VRFY – The disk group is being verified.
• VRSC – The disk group is being scrubbed.
Status Shows the status for the disk group:
• CRIT – Critical. The disk group is online but isn't fault tolerant because some of its disks are down.
• DMGD – Damaged. The disk group is online and fault tolerant, but some of its disks are damaged.
• FTDN – Fault tolerant with a down disk. The disk group is online and fault tolerant, but some of its disks
are down.
• FTOL – Fault tolerant and online. The disk group is online and fault tolerant.
• MSNG – Missing. The disk group is online and fault tolerant, but some of its disks are missing.
• OFFL – Offline. Either the disk group is using offline initialization, or its disks are down and data may be
lost.
• QTCR – Quarantined critical. The disk group is critical with at least one inaccessible disk. For example,
two disks are inaccessible in a RAID-6 disk group or one disk is inaccessible for other fault-tolerant RAID
levels. If the inaccessible disks come online or if after 60 seconds from being quarantined the disk group
is QTCR or QTDN, the disk group is automatically dequarantined.
• QTDN – Quarantined with a down disk. For example, the RAID-6 disk group has one inaccessible disk.
The disk group is fault tolerant but degraded. If the inaccessible disks come online or if after 60 seconds
from being quarantined the disk group is QTCR or QTDN, the disk group is automatically dequarantined.
• QTOF – Quarantined offline. The disk group is offline with multiple inaccessible disks causing user data
to be incomplete, or is an NRAID or RAID-0 disk group.
• STOP – The disk group is stopped.
• UNKN – Unknown.
• UP – Up. The disk group is online and does not have fault-tolerant attributes.
