showspace DESCRIPTION The showspace command displays estimated free space for logical disk creation. SYNTAX showspace [options ] AUTHORITY Any role in the system. OPTIONS The following options are used to select the logical disk creation parameters used for space calculation: -cpg | 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 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 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 Specifies the number of sets in a row using an integer from 1 through 2147483647. If not specified, no row limit is imposed. -ss 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 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. 476 Show Commands
