disk=p:-p
consists of a list of ports (disks) to be used in the construction of
the specified unit type. One or more ports can be specified. Multiple ports can
be specified using a colon (:) or a dash (-) as port index separators. A dash
indicates a range and can be mixed with colons. For example
disk=0:1:2-
5:9:12
indicates port 0, 1, 2 through 5 (inclusive), 9 and 12.
stripe=Stripe
consists of the stripe size to be used. The following table
illustrates the supported and applicable stripes on unit types and controller
models. Stripe size units are in K (kilobytes). If no stripe size is specified,
64K is used by default, if applicable. If you need to change the stripe size after
the unit is created, you can do so my migrating the unit.
group=3|4|5|6|7|8|9|10|11|12
indicates the number of disks per group for a
RAID 50 type. (This attribute can only be used when type=raid50.) Recall
that a RAID 50 is a multi-tier array. At the bottom-most layer, N number of
disks per group are used to form the RAID 5 layer. These RAID 5 arrays are
then integrated into a RAID 0. This attribute allows you to specify the number
of disks in the RAID 5 level. Valid values are 3 through 12.
Note that a sufficient number of disks are required for a given pattern or disk
group. For example, given 6 disks, specifying 3 will create two RAID 5
arrays. With 12 disks, specifying 3 will create four RAID 5 arrays under the
RAID 0 level. With only 6 disks a grouping of 6 is not allowed, as you would
basically be creating a RAID 5.
