Controller Object Commands

www.lsi.com/channel/products

The following table shows supported types and controller models.

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.

If you have a 9750 or 9690SA controller, the syntax is the same even though
you are technically addressing vports.

stripe=size 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,
256K is used by default, if applicable. If you need to change the stripe size
after the unit is created, you can do so by migrating the unit.
