Vdisk properties
When you select the Vdisk component, the Properties for Vdisk table shows:
• Health.
OK. The vdisk is online with all disks working.
Degraded. The vdisk is being reconstructed, as shown by its Current Job property; or, a RAID-6
vdisk has degraded performance due to one missing disk but remains fault tolerant. You can use a
degraded RAID-6 vdisk but resolve the problem as soon as possible.
Fault. The vdisk can perform I/O functions for hosts but is not fault tolerant. Review the status
information and take the appropriate action, such as replacing a disk. You can use the vdisk but resolve
the problem as soon as possible.
Unknown.
• Health Reason. Shows more information about the vdisk's status.
• Name.
• Size. Total storage space in the vdisk.
• Free. Available space in the vdisk.
• Current Owner. Either the preferred owner during normal operation or the partner controller when the
preferred owner is offline.
• Preferred Owner. Controller that owns the vdisk and its volumes during normal operation.
• Serial Number.
• RAID. RAID level of the vdisk and all of its volumes.
• Disks.
• Spares.
• Chunk Size.
• For RAID levels except RAID 50, the configured chunk size for the vdisk.
• 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.
• Minimum Disk Size. Smallest disk in the vdisk.
• Status.
• CRIT: The vdisk is online, however some disks are down and the vdisk is not fault tolerant.
• FTDN: The vdisk is online and fault tolerant, however some of the disks are down.
