Properties are described in alphabetical
order. % of PoolShown by the detail
parameter. The percentage of pool capacity that the disk group occupies. ActionIf Health is not OK, this
field shows recommended actions to take to resolve the health issue. Active Drive Spin Down DelayShown
by the detail parameter. For spinning disks in a linear disk group,
the period of inactivity after which the disks and dedicated spares
will automatically spin down, from 1 to 360 minutes. The value 0 means
spin down is disabled. For virtual storage, not applicable. Active Drive Spin Down EnableShown by the
detail parameter.
- Disabled: DSD is disabled for the
disk group.
- 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.
ADAPT Actual Spare CapacitySown by the detail parameter.
- For an ADAPT disk group, the actual spare capacity
in GiB.
- For a non-ADAPT disk group, N/A.
BlocksizeShown by the detail parameter. The size of a block, in bytes. Chunk SizeShown by the detail parameter.
- For RAID levels except NRAID and RAID 1 and RAID 50,
the 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).
ClassShown by the detail parameter.
- Linear: The disk group acts as a
linear pool.
- Virtual: The disk group is in a
virtual pool.
Current Job CompletionShown by
the detail parameter. See Job%, below Current Job
- DRSC: A disk is being scrubbed.
- EXPD: The disk group is being expanded.
- INIT: The disk group is initializing.
- RBAL: The ADAPT disk group is being
rebalanced.
- RCON: At least one disk in the disk
group is being reconstructed.
- VDRAIN: The virtual 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 disk group and its data
are being removed.
- VRFY: The disk group is being verified.
- VRSC: The disk group is being scrubbed.
- Blank if no job is running.
Current OwnerShown by the detail parameter. See Own, below. DisksThe number of disks in the disk group. FreeThe amount of free space in
the disk group, formatted to use the current base, precision, and
units. Health
- OK
- Degraded
- Fault
- N/A
- Unknown
Health ReasonShown by the detail parameter. See Reason, below. Health RecommendationShown by the detail parameter. See Action, above. Job%
- 0%-99%: Percent complete of running job
- Blank if no job is running (job has completed)
NameThe name of the disk
group. OwnEither the preferred
owner during normal operation or the partner controller when the preferred
owner is offline. PoolThe name
of the pool that contains the disk group. Preferred OwnerShown by the detail parameter. Controller that owns
the disk group and its volumes during normal operation. RAIDThe RAID level of the disk group. ReasonIf Health is not OK, this field
shows the reason for the health state. Sec FmtThe sector format of disks in the disk group.
- 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).
Sector FormatShown by the detail parameter. See Sec Fmt, above. Serial
NumberShown by the detail parameter. The serial number of the disk group. SizeThe capacity of the disk group, formatted to use the
current base, precision, and units. SparesShown by the detail parameter. For a
linear disk group, the number of spares assigned to the disk group.
For a virtual disk group, 0. 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.
- UNKN: Unknown.
- UP: Up. The disk group is online
and does not have fault-tolerant attributes.
Tier
- Performance: The disk group is in
the highest storage tier, which uses SSDs (high speed).
- Standard: The disk group is in the
storage tier that uses enterprise-class spinning SAS disks (10k/15k
RPM, higher capacity).
- Archive: The disk group is in the
lowest storage tier, which uses midline spinning SAS disks (<10k
RPM, high capacity).
- Read Cache: The disk is an SSD providing
high-speed read cache for a storage pool.
