InForm OS Version 2.3.1 Command Line Interface Reference
–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 Device) 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 -i 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.
