InForm OS Version 2.3.1 Command Line Interface Reference
-rpm <number>
Disks must be of the specified speed. Device speeds are shown in the Speed 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:
The columns in the previous example are identified as follows:
■ Pdid. The physical disk on which the chunklets reside.
■ Chnk. The chunklet number.
■ LdName. The name of the logical disk that is using the spare chunklet.
