-sp or
spanlength
<number>
Creates a virtual disk comprised of the
properties supplied. The -sp option is
optional and can be added to the
command line in any order after the
mandatory option combination.
NOTE: Spanlength is applicable
only for RAID 50 and RAID 60. The
minimum permissible spanlength
value for RAID 50 is 3 and for RAID
60 is 4. The number of array disks
for creating a virtual disk should not
be a prime number and should be
divisible by the specified
spanlength.
NOTE: For creating RAID 10, the
PERC 9 firmware suggests the
layout (number of array disks) with
uneven span (spans with unequal
number of array disks), though in a
span the number of disks remain
even. For example, for 32 disks,
RAID 10 is created with all the disks
in one span and for 34 disks, RAID
10 is created with 16 disks in one
span and 18 disks in the other span.
For SCSI controllers, the value of LUN
should always be 0.
For SAS controllers, the value of
enclosure can be non-zero, in which
case you must specify values for
channel, target, and enclosure.
