size string The size of the disk group, formatted to use the current base, precision, and units.

  • A: Controller A.
  • B: Controller B.
owner-numeric uint32 Numeric equivalents for owner values.
  • 0: B
  • 1: A
preferred-owner string Controller that owns the disk group and its volumes during normal operation.
  • A: Controller A.
  • B: Controller B.
preferred-owner- numeric uint32 Numeric equivalents for preferred-owner values.

raidtype string The disk-group RAID level.

  • RAID50
  • ADAPT
raidtype-numeric uint32 Numeric equivalents for raidtype values.
  • 0: RAID0

  • 2: ADAPT
  • 3: RAID3
  • 5: RAID5
  • 6: NRAID
  • 8: RAID50
  • 10: RAID10
  • 11: RAID6
storage-type string
  • Linear: The disk group acts as a linear pool.
  • Virtual: The disk group is in a virtual pool.
storage-type- numeric uint32 Numeric equivalents for storage-type values.
  • 0: Linear
  • 1: Virtual
diskcount uint16 Number of disks in the disk group.
sparecount uint16 Number of spare disks assigned to the disk group.
chunksize string
  • For RAID levels except NRAID, RAID 1, and RAID 50, the configured chunk size for the disk group.
  • For NRAID and RAID 1, chunk size has no meaning and is therefore shown as not applicable ( N/A ).
  • For RAID 50, the disk-group chunk size calculated as:configured-chunk- size x (subgroup-members- 1) . For a disk group configured to use 64-KB chunk size and 4-disk subgroups, the value would be 192k (64KB x 3).
status string Disk-group status.
  • 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.
  • 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. 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.
  • UP: Up. The disk group is online and does not have fault-tolerant attributes.
  • UNKN: Unknown.
status-numeric uint32 Numeric equivalents for status values.
  • 0: FTOL
  • 1: FTDN
  • 2: CRIT
  • 3: OFFL
  • 4: QTCR
  • 5: QTOF

  • 7: STOP
  • 8: MSNG
  • 9: DMGD
  • 250: UP
  • other: UNKN

  • Enabled - all spinning: DSD is enabled for the disk group.
  • Partial spin-down: DSD is enabled for the disk group and its disks are partially spun down to conserve power.
  • Full spin-down: DSD is enabled for the disk group and its disks are fully spun down to conserve power.
disk-dsd-enable-vdisk-numeric uint32 Numeric equivalents for disk-dsd-enable-vdisk values.

  • 512n: All disks use 512-byte native sector size. Each logical block and physical block is 512 bytes.
  • 512e: All disks use 512-byte emulated sector size. Each logical block is 512 bytes and each physical block is 4096 bytes. Eight logical blocks will be stored sequentially in each physical block. Logical blocks may or may not be aligned with physical block boundaries.
  • Mixed: The disk group contains a mix of 512n and 512e disks. This is supported, but for consistent and predictable performance, do not mix disks of different sector size types (512n, 512e).
