HP 3PAR Command Line Interface Reference (OS 3.1.2 MU2) (QL226-97016, June 2013)

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 LDs 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. 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 that are connected to node 2 through their primary path.
• The following options are used only for VV templates:
–type cpvv|tpvv|none
Specifies the type of VV for the template is being created. Valid arguments are cpvv, tpvv, or
none. Use cpvv if the –cpg <CPG_name> option is used. If creating a template for creating
TPVVs, use tpvv. If cpvv or tpvv are not specified, the default value is none meaning the created
template is applicable for the creation of any volume type. The -type cpvv option is deprecated
and will be removed in a subsequent release.
–cpg <CPG_name>
Specifies that the snapshot data space and snapshot administration space are provisioned from
the indicated CPG (<CPG_name>). The template with this option can only be used with
createaldvv command. This option is deprecated and will be removed in a subsequent release.
–aw <percent>
Specifies the allocation warning threshold of the CPG. When the snapshot data space of the VV
exceeds the specified percentage of the virtual volume size, an alert is generated. The template
with this option can only be used with createaldvv command. This option is deprecated and
will be removed in a subsequent release.
–al <percent>
