Command Reference Guide

–tc_lt <number>
Specifies that PDs with total chunklets less than the number specified are selected.
–fc_gt <number>
Specifies that PDs with free chunklets greater than the number specified are selected.
–fc_lt <number>
Specifies that PDs with free chunklets less than the number specified are selected.
–devid <model>
Specifies that PDs 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 <device_type>
Specifies that PDs 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.
–domain <domain>
Specifies the domain. The default is to create logical disk(s) in the current domain, or no domain
if the current domain is not set.
–wait <secs>
If the createald command fails due to the lack of clean space, the -wait option specifies the
number of seconds to wait for the system to clean the dirty space before returning. If -wait 0 is
issued, the command returns immediately. If this option is not used, the command will keep waiting
for dirty chunklets to be cleaned if enough space will be available with the dirty chunklets cleaned.
–dr
Specifies that the command is a dry run and that no logical disks or Virtual Volumes are created.
–verbose on|off
Specifies that verbose output is either enabled (on) or disabled (off). If not specified, verbose
output is disabled.
–cpsd <CPG_name>
Specifies that the logical disk created is added to the specified Common Provisioning Group’s
(CPG’s) snapshot data space.
–cpsa <CPG_name>
Specifies that the logical disk created is added to the specified CPG’s snapshot administration
space.
-cpusr <CPG_name>
Specifies that the logical disk being created is added to the specified CPG USR space.
