tc_gt <number>
Specifies that PDs with total chunklets greater than the number specified are selected.
tc_lt <number>
Specifies that PDs with total chunklets less than the number specified are selected.
fc_gt <number>
Specifies that PDs with free chunklets greater than the number specified are selected.
fc_lt <number>
Specifies that PDs with free chunklets less than the number specified are selected.
devid <model>
Specifies that PDs identified by their models are selected. Models can be specified in a
comma-separated list. Models can be displayed by issuing the showpd -i command.
devtype <type>
Specifies that PDs must have the specified device type (FC for Fibre Channel, NL for nearline, or
SSD for solid state drive) to be used. Device types can be displayed by issuing the showpd
command.
-rpm <number>
Disks must be of the specified 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
<PD_ID>|<pattern>... (deprecated usage)
Specifies the PD IDs or the PD ID pattern for disks whose chunklets are to be displayed.
RESTRICTIONS
If no option is specified, the showpdch command defaults to displaying information about chunklets
used for logical disks (ld).
EXAMPLES
The following example displays information about chunklets on PD 1:
cli% showpdch 1
