Command Line Interface Reference InForm OS Version 2.3.1
The following option specifies the name of the template used to create a TPVV.
–templ <template_name>
Use the options defined in template <template_name>. The template is created using the
createtemplate command. Options specified in the template are read-only or read-
write. The read-write options may be overridden with new options at the time of their
creation, but read-only options may not be overridden at the time of creation. Options not
explicitly specified in the template take their default values, and all of these options are
either read-only or read-write (using the
-nro or -nrw options of the createtemplate
command). If not included, the
-size and -cpg options are automatically treated as read-
write even if the other unincluded properties are marked read-only.
The following option is used to create the snapshot space of the TPVV:
-snp_cpg <snp_cpg>
Specifies the name of the Commonly Provisioned Group (CPG) from which the snapshot
space will be allocated.
The following options are used to set the allocation policies of the TPVV:
-usr_aw <percent>
This option enables user space allocation warning. It specifies that a warning alert is
generated when the user space of the TPVV exceeds the specified percentage of the VV
size.
-usr_al <percent>
This option sets the user space allocation limit. The user space of the TPVV is prevented
from growing beyond the indicated percentage of the VV size. After this size is reached,
any new writes to the VV will fail.
-snp_aw <percent>
Enables a snapshot space allocation warning. A warning alert is generated when the
snapshot space of the VV exceeds the indicated percentage of the VV size.
-snp_al <percent>
Sets a snapshot space allocation limit. The snapshot space of the VV is prevented from
growing beyond the indicated percentage of the VV size.
-spt <sectors_per_track>
Defines the VV 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.
