HP 3PAR OS 3.1.3 Command Line Interface Reference

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. If it is not specified, the default device type is FC.
-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 connected to node 2 through their primary path.
–sax <LD_name>[,<LD_name>...]
Specifies that the logical disk, as identified with the <LD_name> argument, used for snapshot
administration space allocation be removed. The <LD_name> argument can be repeated to specify
multiple logical disks.
–sdx <LD_name>[,<LD_name>...]
Specifies that the logical disk, as identified with the <LD_name> argument, used for snapshot data
space allocation be removed. The <LD_name> argument can be repeated to specify multiple LDs.
–name <newname>
Specifies the name of the Common Provisioning Group (CPG) to be modified to. <newname> can
be up to 31 characters in length.
SPECIFIERS
<CPG_name>
Specifies the name of the CPG being modified.
RESTRICTIONS
• Access to all domains is required to run this command.
• This command sets the parameters that will be used for future grows. Unless the the only growth
parameters (-sdgs, -sdgw or -sdgl) are being changed, this command will OVERWRITE
all previously-set parameters.
EXAMPLES
The following example displays the modification of the auto-growth parameters for CPG cpg1:
cli% setcpg –sdgs 16g –sdgl 48g –sdgw 36g cpg1
The following example removes the -cpg pattern:
cli% setcpg -ha cage -t r5 -p -cg "" -devtype FC cpg1
NOTES
• With this command, you can change the device type of a CPG from logical disks of one
device type to logical disks of another device type (device types are Fibre Channel (FC),
