HP 3PAR OS 3.1.3 Command Line Interface Reference

showspace
DESCRIPTION
The showspace command displays estimated free space for logical disk creation.
SYNTAX
showspace [options <arg>]
AUTHORITY
Any role in the system.
OPTIONS
The following options are used to select the logical disk creation parameters used for space
calculation:
–cpg <CPG_name>|<pattern>
Specifies that logical disk creation parameters are taken from CPGs that match the specified CPG
name or pattern, indicated with a glob-style pattern (see “Glob-Style Pattern” (page 12) for more
information). Multiple CPG names or patterns can be specified using a comma separated list, for
example cpg1,cpg2,cpg3. Only the -hist option can be specified with the -cpg option.
–hist
Specifies that free space history over time for CPGs specified with the –cpg option is displayed.
This option can only be used if the –cpg option is specified.
–t <RAID_type>
Specifies the RAID type of the logical disk: r0 for RAID-0, r1 for RAID-1, 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 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 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.
