Wcache—Sets the logical drive write cache mode:
●
WT - write-through disabled
●
WB - write-back enabled
●
WBB - write-back enabled (when protected by battery or flash backup module)
●
MaxCacheReadCache—Sets the logical drive SSD read cache mode:
●
ION - maxCache on
●
IOFF - maxCache off
●
MaxCacheWriteCache—Sets the logical drive SSD write cache mode:
●
ION - maxCache on
●
IOFF - maxCache off
●
MaxCacheWritePolicy—Sets the maxCache write cache policy:
●
WB - write back enabled. maxCache will store the data on the SSD and write it back to
●
the hard disks when there is little or no impact on performance. This is the default
policy.
INSTWB - instant write back enabled. In addition to the default policy, maxCache will
●
create "dirty pages" on-the-fly for full-stripe writes if there is room on the SSD and the
number of dirty pages is below the threshold.
WT - write through enabled. Similar to instant write back, but full-stripe writes go to
●
both the cache and hard disk and no dirty pages are created on-the-fly.
This argument is valid only if MaxCacheWriteCache is ION.
Note:
For more informattion about write cache policy, see setmaxcache on
Size indicates the size of the logical drive in megabytes. Use MAX to set size to available space.
RAID# indicates the RAID level for the new logical drive. 0, 1, 1E, 10, 5, 5EE, 50, 6, 60, and
volume are supported.
Channel# Drive# lists the space-delimited channel number and device number pairs for each
device to add to the logical drive.
Rvolume is the RAID level for a RAID volume logical drive.
LD# is the logical drive numbers for two or more logical drives to be concatenated into the
RAID volume.
Noprompt: No prompt for confirmation
