Setting Retention Times for Virtual Volumes
3PAR InForm CLI Administrator’s Manual InForm OS Version 2.3.1
■ The retention time can be increased but it cannot be decreased.
■ 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.
