Command Line Interface Reference InForm OS Version 2.3.1
–ssz <size_number_chunklets>
Specifies the set size in terms of chunklets. The default depends on the RAID type specified:
2 for RAID-1, 4 for RAID-5, and 8 for RAID-6.
–rs <size>
Specifies the number of sets in a row using an integer from 1 to 2147483647. If not
specified, no row limit is imposed.
–ss <size_KB>
Specifies the step size from 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 location preference 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 disks. Patterns are used to select disks that are used for creating LDs.
If no pattern is specified, the option defaults to 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), FC, and
Solid State Drive (SSD) drives.
The following arguments can be specified as patterns for this option:
–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 number(s).
