• Current Owner. Either the preferred owner during normal operation or the partner controller when the preferred owner is offline. • Disks. Quantity of disks in the vdisk. • Spares. Quantity of dedicated spares in the vdisk. Viewing information about a vdisk In the Configuration View panel, right-click a vdisk and select View > Overview. The Vdisks Overview table shows: • The overall health, capacity, and space usage of the vdisk • The overall health, quantity, capacity, and space usage of disks in the vdisk • The quantity, capacity, and space usage of volumes in the vdisk • The quantity, capacity, and space usage of snap pools in the vdisk For descriptions of storage-space color codes, see About storage-space color codes on page 33. Select a component to see more information about it. 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. N/A. Health status is not available. • Health Reason. Shows more information about the vdisk's status. • Name. Vdisk 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. 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 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. Date and time when the vdisk was created. • Minimum Disk Size. Capacity of the 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. • FTOL: The vdisk is online and fault tolerant. 88 Viewing system status

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.
N/A. Health status is not available.
•
Health Reason. Shows more information about the vdisk's status.
•
Name. Vdisk name.
•
Size. Total storage space in the vdisk.
•
Free. Available space in the vdisk.

•
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 (

- 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: The vdisk is online, however some disks are down and the vdisk is not fault tolerant.
•
