Dell 38XX, 34XX, 32XX, 36XX manual Set Virtual Disk, Syntax Applicable To Only One Virtual Disk

Set Virtual Disk

Description

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 RAID controller module failure.
