show vdisks


Description	Shows information about all or specified linear disk groups. This command applies to linear storage only.
Minimum role	monitor
Syntax	show vdisks [`vdisks`]
Parameters	`vdisks` Optional. A comma-separated list of the names or serial numbers of the linear disk groups to show information about. A name that includes a space must be enclosed in double quotes.
Output	Name The name of the disk group. Size The size of the disk group. Free The amount of free (available) space in the disk group. Own Either the preferred owner during normal operation or the partner controller when the preferred owner is offline. Pref The controller that owns the disk group and its volumes during normal operation. RAID The disk-group RAID level. Class Linear: The disk group acts as a linear pool. Virtual: The disk group is in a virtual pool. Disks The number of disks in the disk group. Spr The number of spares assigned to the disk group. Chk 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 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 vdisk 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 vdisk 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. Jobs Shows whether a job is running and its percent complete. 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 vdisk 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. Job% 0%-99%: Percent complete of running job Blank if no job is running (job has completed) Serial Number The serial number of the disk group. Spin Down 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. SD Delay For spinning disks in non-ADAPT disk groups, the period of inactivity after which the disk group’s disks and dedicated spares will automatically spin down, from 1 to 360 minutes. The value 0 means spin down is disabled. Sec Fmt The 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 rotational speed or sector size types (512n, 512e). Health OK Degraded Fault N/A Unknown Reason If Health is not OK, this field shows the reason for the health state. Action If Health is not OK, this field shows recommended actions to take to resolve the health issue.
