-devtype Specifies that physical disks must have the specified device type (FC for Fibre Channel or NL, nearline, or SSD for solid state drive) to be used. Device types can be displayed by issuing the showpd command. If it is not specified, the default device type is FC. -rpm Specifies that disks must be of the indicated speed. Device speeds are shown in the RPM column of the showpd command. The number does not represent a rotational speed for the drives without spinning media (SSD). It is meant as a rough estimation of the performance difference between the drive and the other drives in the system. For FC and NL drives, the number corresponds to both a performance measure and actual rotational speed. For SSD drive, the number is to be treated as relative performance benchmark that takes into account in I/O per second, bandwidth and the access time. Disks that satisfy all of the specified characteristics are used. For example -p -fc_gt 60 -fc_lt 230 -nd 2 specifies all the disks that have greater than 60 and less than 230 free chunklets and that are connected to node 2 through their primary path. SPECIFIERS None. RESTRICTIONS The -cpg and -hist options cannot be used with any other option. EXAMPLES The following example displays the estimated free space for a RAID-1 LD: cli% showspace -t r1 --Estimated(MB)--- RawFree UsableFree 13824 6912 NOTES • The showspace command includes chunklets in the process of being initialized as shown by the Normal, Unused, Uninit column of showpd -c. The space represented by these chunklets will not actually be available until the initialization process is complete. • The space calculated is an estimate and not an exact figure. • For this command: MB = 1048576 bytes. 478 Show Commands
