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.
Syntax Applicable to One or More Virtual Disks
set (allVirtualDisks | virtualDisk
[" virtualDiskName "] |
virtualDisks [" virtualDiskName1 " ...
" virtualDiskNamen "] |virtualDisk < wwid >)
mediaScanEnabled=(TRUE | FALSE)
mirrorCacheEnabled=(TRUE | FALSE)
modificationPriority=(highest | high | medium |
low | lowest)owner=(0 | 1)
writeCacheEnabled=(TRUE | FALSE)
cacheReadPrefetch=(TRUE | FALSE)
NOTE:
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.
Syntax Applicable to Only One Virtual Disk
Set (virtualDisk [" virtualDiskname "] | virtualDisk
< wwid >) addCapacity= virtualDiskcapacity
[addPhysicalDisks=( enclosureID0,slotID0 ...
enclosureIDn,slotIDn )] consistencyCheckEnabled=
(True | False) segmentSize= segmentSizeValue
userLabel=" virtualDiskName "
Syntax Applicable to Virtual Disk Mapping
set (virtualDisk [" virtualDiskName "] | virtualDisk
< wwid > | accessVirtualDisk) logicalUnitNumber=LUN
