HP 3PAR OS 3.1.3 Command Line Interface Reference

range of disk positions is separated with a hyphen (0–3). The specified position(s) must contain
disks.
–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 (1,2,3). A range of disks is separated with a hyphen
(0–3). Disks must match the specified ID(s).
NOTE: The following arguments, –tc_gt , –tc_lt , –fc_gt , –fc_lt , –devid , and –devtype are used
to limit the disks that are used to create logical disks based on the characteristics of the disk drive.
–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 RPM 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.
