Parameter owner cacheReadPrefetch segmentSize usageHint Description 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. If you do not specify an owner, the RAID controller module firmware determines the owner. NOTE: The owner parameter defines which RAID controller module owns the virtual disk. The preferred owner of a virtual disk is the RAID controller module that currently owns the disk group. The setting to turn on or turn off cache read prefetch. To turn on cache read prefetch, set this parameter to TRUE. To turn off cache read prefetch, set this parameter to FALSE. Amount of data (in kilobytes) that the RAID controller module writes on a single physical disk in a virtual disk before writing data on the next physical disk. Valid values are 8, 16, 32, 64, 128, 256, or 512. For information about the segmentSize parameter, see "Using the Auto Configure Command" on page 53. The settings for both the cacheReadPrefetch parameter and the segmentSize parameter should be the default values. The default values are based on the typical I/O usage pattern of the application that is using the virtual disk. Valid values are fileSystem, dataBase, or multiMedia. 140 Script Commands

The
owner
parameter defines which RAID
controller module owns the virtual disk. The preferred
owner of a virtual disk is the RAID controller module that
currently owns the disk group.
