Command Line Interface Reference InForm OS Version 2.3.1

–rs <size>

Specifies the number of sets in a row using an integer from 1 through 2147483647. If not

specified, no row limit is imposed.

–ss <size_KB>

Specifies the step size in kilobytes using 32 KB to 512 KB. The step size should be a power of

2 and a multiple of 32. If no value is entered, the step size defaults to 256 KB for RAID-0

and RAID-1, and 128 KB for RAID-5. For RAID-6, the default is a function of the set size.

–ha port|cage|mag

Specifies that the layout must support the failure of one port pair, one cage, or one drive

magazine (mag). This option has no meaning for RAID-0.

–ch first|last

Specifies the chunklet characteristics, either first (attempt to use the lowest numbered

available chunklets) or

last (attempt to use the highest numbered available chunklets). If

no argument is specified, the default characteristic is

first.

–p <pattern>

Specifies a pattern for candidate disks. Patterns are used to disks that are used for creating

LDs. If no pattern is specified, the option defaults to all Fibre Channel (FC) disks.

If specified multiple times, each instance of the specified pattern adds additional candidate

disks that match the pattern. The

-devtype pattern cannot be used to mix Near Line (NL)

and FC, and Solid State Drive (SSD) drives:

–nd <item>

Specifies one or more nodes. Nodes are identified by one or more integers (item).

Multiple nodes are separated with a single comma (

1,2,3). A range of nodes is

separated with a hyphen (0–7). The primary path of the disks must be on the

specified node(s).

–st <item>

Specifies one or more PCI slots. Slots are identified by one or more integers (item).

Multiple slots are separated with a single comma (

1,2,3). A range of slots is

separated with a hyphen (

0–7). The primary path of the disks must be on the

specified PCI slot(s).

NOTE: An item is specified as an integer, a comma-separated list of integers, or a

range of integers specified from low to high.
