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 initializing online or is reconstructing, 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.
