Command Reference Guide

Use the options defined in template <template_name>. The template is created using the
createtemplate command. Options specified in the template are read-only or read-write. The
read-write options may be overridden with new options at the time of their creation, but read-only
options may not be overridden at creation time. Options not explicitly specified in the template
take their default values, and all of these options are either read-only or read-write (using the –nro
or –nrw options of the createtemplate command). Sizing options from the template are
ignored. This command does not change the size of the VV on which it acts.
–t <RAID_type>
Specifies the RAID type of the Logical Disk (LD): r0 for RAID-0, r1 for RAID-1, or r5 for RAID-5,
or r6 for RAID-6. If no RAID type is specified, the default is r1.
–ssz <size_number_chunklets>
Specifies the set size in the number 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. The <size> is a positive integer. 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, 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:
NOTE: An item is specified as an integer, a comma-separated list of integers, or a range of
integers specified from low to high.
–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).
–pt <item>
Specifies one or more ports. Ports are identified by one or more integers (<item>). Multiple ports
are separated with a single comma (1,2,3). A range of ports is separated with a hyphen (0–5).
The primary path of the disks must be on the specified port number(s).
