Command Reference Guide

Specifies the allocation limit threshold of the CPG. The snapshot data space is prevented from
growing beyond the specified percentage of the virtual volume size. The template with this option
can only be used with createaldvv command. This option is deprecated and will be removed
in a subsequent release.
–size <size>[g|G|t|T]
Specifies the size of the virtual volume and logical disk in megabytes. Size can be specified in
megabytes (default) or in gigabytes by using the g|G parameter and terabytes by using the t|T
parameter. To specify the size in gigabytes, enter g or G, for terabytes, enter t or T, directly after
the specified size (no space).
–szs <size>[g|G|t|T]
By default, specifies the size of the snapshot volume in megabytes using an integer from 0 through
2096128(2047 GB). Size can be specified in megabytes (default) or in gigabytes by using the
g|G parameter and terabytes by using the t|T parameter. To specify the size in gigabytes, enter
g or G, for terabytes, enter t or T, directly after the specified size (no space). If not specified,
snapshot space is 0. This option cannot be used with the –pct option. The template with this option
can only be used with the createaldvv command. This option is deprecated and will be removed
in a subsequent release.
–pct <prc>
Specifies the size of the snapshot volume as a percentage of the user volume. If not specified, the
default value is 0 percent of your user volume. This option cannot be used with the –szs option.
If used with the –cpg <CPG_name>option, the percentage value is 0. The template with this
option can only be used with the createaldvv command. This option is deprecated and will be
removed in a subsequent release.
-spt <sectors_per_track>
Defines the virtual volume geometry sectors per track value that is reported to the hosts through the
SCSI mode pages. The valid range is between 4 to 8192 and the default value is 304.
-hpc <heads_per_cylinder>
Allows you to define the virtual volume geometry heads per cylinder value that is reported to the
hosts though the SCSI mode pages. The valid range is between 1 to 255 and the default value is
8.
–pol <pol>[,<pol>...]
Specifies the policy that the created virtual volume follows. If an argument is not specified, the
option defaults to stale_ss.
stale_ss
Specifies that invalid snapshot volumes are permitted. Failure to update snapshot data does not
affect the write to the base volume, but the snapshot is considered invalid.
no_stale_ss
Specifies that invalid snapshot volumes are not permitted. Failure to update a snapshot is considered
a failure to write to the base volume.
one_host
This constrains the export of a volume to one host or one host cluster (when cluster names can be
used as a host name).
no_one_host
This policy should only be used when exporting a virtual volume to multiple hosts for use by a
cluster-aware application, or when “port presents” VLUNs are used. This is the default policy setting.
