Parameters
Parameter Description
allVirtualDisks Specifies the properties for all virtual disks in the
storage array.
virtualDisk or virtualDisks
(name) Specifies the name of the virtual disk for which to
define properties. You can enter more than one virtual
disk name if you use the virtualDisks parameter. You
must put quotation marks (" ") and brackets ([ ])
around the virtual disk name. The virtual disk name
and quotation marks must be inside the brackets.
virtualDisk
(wwid) Specifies the WWID of the virtual disk for which you
are setting properties. You can use the WWID instead
of the virtual disk name to identify the virtual disk. You
must put angle brackets (< >) around the WWID.
mediaScanEnabled Turns media scan for the virtual disk on or off. To turn
media scan on, set to TRUE. To turn media scan off,
set to FALSE. If media scan is disabled at the storage
array level, this parameter has no effect.
mirrorCacheEnabled Turns the mirror cache on or off. The default
setting is TRUE. To turn the mirror cache off, set
this parameter to FALSE.
NOTE:
Data loss can occur if a RAID controller module
fails when cache mirroring is set to FALSE on the virtual
disks owned by the failed controller.
modificationPriority Specifies the priority for virtual disk modifications
while the storage array is operational. Valid entries are
highest, high, medium, low, or lowest.
NOTE:
Modification priority defines the amount of
system resources used when modifying virtual disk
properties. If you select the highest priority level, the
virtual disk modification uses the most system resources,
which decreases performance for host data transfers.
