A range of disk positions is separated with a hyphen (0-3). The specified position(s) must contain disks. -dk Specifies one or more physical disks. Disks are identified by one or more integers (). 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 are used to limit the disks that are used to create logical disks based on the characteristics of the disk drive. -tc_gt Specifies that physical disks with total chunklets greater than the number specified are selected. -tc_lt Specifies that physical disks with total chunklets less than the number specified are selected. -fc_gt Specifies that physical disks with free chunklets greater than the number specified are selected. -fc_lt Specifies that physical disks with free chunklets less than the number specified are selected. -devid 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 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 Disks must be of the specified speed. Device speeds are shown in the RPM 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.

A 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 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
-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.
SPECIFIERS
