–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, 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 location is
first.
–p <pattern>
Specifies a pattern for candidate disks. Patterns are used to select disks that are used for
creating logical disks. 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), 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.
