Parameter owner writeCacheEnabled cacheReadPrefetch addCapacity addPhysicalDisks consistencyCheckEnabled Description Specifies the RAID controller module that owns the virtual disk. Valid RAID controller module identifiers are 0 or 1, where 0 is the RAID controller module on the left and 1 is the RAID controller module on the right when viewed from the rear of the enclosure. Use only if you want to change the virtual disk owner. Turns the write cache on or off. To turn on the write cache, set this parameter to TRUE. To turn off the write cache, set this parameter to FALSE. The default value is TRUE. This parameter turns the cache read prefetch on or off. To turn off cache read prefetch, set this parameter to FALSE. To turn on cache read prefetch, set this parameter to TRUE. The default value is TRUE. Increases storage size (capacity) of the virtual disk for which you are defining properties. Size is defined in units of bytes, kilobytes, megabytes, or gigabytes, or terabytes. The default units are bytes. Virtual Disk capacity expansion increases the size of the logical unit that is exposed by the RAID controller. Refer to your OS documentation for additional information about how the OS can recognize the additional capacity on the virtual disk and increase the size of OS volumes on the virtual disk. Adds new physical disks to the virtual disk. Specify the enclosure ID and slot ID for each physical disk that you assign to the virtual disk. Enclosure ID values are 0 to 99. Slot ID values are 0 to 31. You must put brackets ([ ]) around the enclosure ID values and the slot ID values. Use with the addCapacity parameter if you must specify additional physical disks to accommodate the new size. Turns consistency checking during a media scan on or off. To turn consistency checking on, set to TRUE. To turn consistency checking off, set to FALSE. 192 Script Commands
