Command Line Interface Reference InForm OS Version 2.3.1
–fc_gt <number>
Specifies that physical disks with free chunklets greater than the number specified
are selected.
–fc_lt <number>
Specifies that physical disks with free chunklets less than the number specified are
selected.
–devid <model>
Specifies that physical disks 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 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
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
None.
RESTRICTIONS
The –cpg and -hist options cannot be used with any other option.
