The command uses the freespace(s) from the SCSI device(s)
you specify to create the RAID-5 set. The size that the
command uses from these device(s) is identical to the one you
specify in the free_space parameter. The minimum number
of partitions in a RAID-5 set is 3, and the maximum number of
partitions is 16.

Switches

/cache{=boolean}
When FALSE (the default), the command causes the controller to
disable the array's array cache. FALSE means:
Disables the read-ahead cache.
Disables the write-back cache.
When TRUE, write cache is enabled, providing maximum
performance.
Notes
When the write cache is enabled, there is a potential for data
loss or corruption during a power failure.
You can enable write cache only if a native operating system's
file system—in Windows, the NTFS or FAT file system—
resides on the array.
If you do not want to enable the stripe set's array cache when
you create it, you can do so later by using the container set
cache command.
/clear{=boolean}
Specifies whether to set up the parity during RAID-5 creation
by clearing the entire RAID-5 set. If you specify TRUE, the
command sets up the parity during RAID-5 creation by
clearing the RAID-5 set.
The default is FALSE; the command does not clear the entire
RAID-5 set.
If you use neither this switch nor the /scrub switch, the
command uses the scrub method by default.
Unlike the scrub method where the drive is immediately
available, the clear method does not make the drive available
for use until the parity-initialize operation completes.
