Dell PowerVault MD3220 - Set Virtual Disk

218 Script Commands
Set Virtual Disk
This command defines the properties for a virtual disk. You can use most of
the parameters to define properties for one or more virtual disks, however,
some of the parameters define properties for only one virtual disk at a time.
The syntax definitions are separated to show which parameters apply to
several virtual disks and which apply to only one virtual disk. The syntax for
virtual disk mapping is listed separately.

CAUTION: Enabling Write Cache on a virtual disk generally improves
performance for applications with significant Write content (unless the
application features a continuous string of Writes. However,
Write Cache does
introduce some risk of data loss in the unlikely event of a controller failure.
