Command Line Interface Reference InForm OS Version 2.3.1
-dk <item>
Specifies one or more physical disks. Disks are identified by one or more integers
(
item). Multiple disks are separated with a single comma (e.g. 1,2,3). A range of
disks is separated with a hyphen (e.g.
0-3). Disks must match the specified ID(s).
-tc_gt <number>
Specifies that physical disks with total chunklets greater than the number specified
are selected.
-tc_lt <number>
Specifies that physical disks with total chunklets less than the number specified are
selected.
-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,
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 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.
