HP 3PAR Command Line Interface Reference (OS 3.1.2 MU2) (QL226-97016, June 2013)

–devtype <type>
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 <number>
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

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.
