•
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 domain creation with
the
createdomain
command, or applied to an existing domain with the
setdomain
command.
•
If the volume belongs to a domain, then the volume retention time cannot exceed the domain's
maximum retention time.
•
A volume with remaining retention time cannot be removed until the end of the retention period.
You can use the
-retain
option to set volume retention times while issuung 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 that 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 virtual volumes, issue the
removevv <VV_name>
or
removevv <pattern>
command,
where:
•
<VV_name>
represents the names of the virtual volumes to be removed.
•
<pattern>
represents 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 Command
Line Interface Reference and the HP 3PAR CLI Help.
