MSA 2040 SMU Reference Guide

Viewing information about a vdisk 103
• Serial Number. Vdisk serial number.
• RAID. RAID level of the vdisk and all of its volumes.
• Disks. Quantity of disks in the vdisk.
• Spares. Quantity of dedicated spares in the vdisk.
• Chunk Size.
• For RAID levels except NRAID, RAID 1, and RAID 50, the configured chunk size for the vdisk.
• For NRAID and RAID 1, chunk size has no meaning and is therefore shown as not applicable (N/A).
• For RAID 50, the vdisk chunk size calculated as: configured-chunk-size x (subvdisk-members - 1). For a vdisk
configured to use 32-KB chunk size and 4-disk sub-vdisks, the value would be 96k (32KB x 3).
• Created. Date and time when the vdisk was created.
• Minimum Disk Size. Capacity of the smallest disk in the vdisk.
• Status.
• CRIT: Critical. The vdisk is online but isn’t fault tolerant because some of its disks are down.
• 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.
• OFFL: Offline. Either the vdisk 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 vdisk 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 vdisk is QTCR or QTDN, the vdisk is
automatically dequarantined.
• QTDN: Quarantined with a down disk. The RAID-6 vdisk has one inaccessible disk. The vdisk is fault tolerant
but degraded. If the inaccessible disks come online or if after 60 seconds from being quarantined the vdisk is
QTCR or QTDN, the vdisk is automatically dequarantined.
• QTOF: Quarantined offline. The vdisk is offline with multiple inaccessible disks causing user data to be
incomplete, or is an NRAID or RAID-0 vdisk.
• STOP: The vdisk is stopped.
• UNKN: Unknown.
• UP: Up. The vdisk is online and does not have fault-tolerant attributes.
• Current Job. If a utility is running on the vdisk, this field shows the utility’s name and progress.
• Disk Scrub: Disks in the vdisk are being scrubbed.
• Expand: The vdisk is being expanded.
• Initialize: The vdisk is being initialized.
• Reconstruct: The vdisk is being reconstructed.
• Verify: The vdisk is being verified.
• Media Scrub: The vdisk is being scrubbed.
• Drive Spin Down Vdisk Enable. Shows whether drive spin down is enabled or disabled for this vdisk.
A second table displays information about unhealthy components. If all components are healthy, this table displays
the text, “There is no data for your selection.”
NOTE: In the Configuration View panel, if a vdisk contains more than one type of disk, its RAID-level label includes
the suffix -MIXED.
