HP 3PAR InForm OS 3.1.1 CLI Administrator's Manual

• If both of the retention time and expiration time are specified, the retention time cannot be
greater than the expiration time.
• The retention time can be set in hours or days. The minimum retention time is 1 hour and the
maximum retention time is 43800 hours (1,825 days or 5 years). The default is 336 hours
(14 days). The vvMaxRetentionTime system parameter determines the maximum retention.
This parameter can be set with the setsys command.
• The maximum retention time for a volume in a domain can be set during the domain creation
time or applied to an existing domain with the createdomain or setdomain commands.
• If the volume belongs to a domain, then volume’s retention time cannot exceed the domain's
maximum retention time.
• A volume with retention time cannot be removed until end of retention time period.
You can use the -retain option to set volume retention times with the following commands:
• createvv
• setvv
• createsv
• creategroupsv
• To create a virtual volume that cannot be deleted for a specified number of hours, issue the
createvv -retain <time> d|D|h|H <CPG_name> -snp_cpg <CPG_name>
<user_CPG> <VV_name> <VV_size g|G|t|T> command, where:
◦ -retain <time> d|D|h|H specifies the volume cannot be removed from the system
for the specified number of hours or days. The value for <time> must be a positive integer
in the range of 1 hour to 43,800 hours (1,825 days). The value for <time> can be
specified in days with d|D or hours with h|H. For example, 14d specifies 14 days.
◦ <CPG_name> is the name of the CPG from which the volume will draw its snapshot space
and administration space.
◦ <user_CPG> is the name of the CPG from which the created virtual volume will draw
its user space.
◦ <VV_name> is the name of the volume being created. The name can be up to 31
characters.
◦ <VV_size g|G|t|T> is the size of the volume in MB, GB, or TB. If g|G|t|T is not
specified, VV_size is the number of MBs. For example, 50g specifies 50 GBs.
Removing Virtual Volumes
• To remove virtual volumes, issue the removevv <VV_name> or removevv <pattern>
command, where:
◦ <VV_name> is the name(s) of the virtual volume(s) to be removed.
◦ <pattern> is the name of the pattern according to which virtual volumes are to be
removed.
For a complete list of options available for the removevv command, see the HP 3PAR InForm OS
Command Line Interface Reference and InForm OS CLI Help.
