InForm OS Version 2.3.1 Command Line Interface Reference
–fc_lt <number>
Specifies that physical disks with free chunklets less than the number specified are
selected.
–devid <ID>
Specifies that physical disks identified by their device IDs be selected for logical disk
creation. Device IDs can be specified in a comma-separated list. Device IDs can be
displayed by issuing the
showpd –i command.
–devtype <model>
Specifies that physical disks must have the specified device type (FC for Fibre
Channel,
NL for Nearline, 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.
SPECIFIERS
