InForm OS Version 2.3.1 Command Line Interface Reference
-retain <time>[d|D|h|H]
Specifies the amount of time, relative to the current time, that the volume will be retained.
<time> is a positive integer value and in the range of 1 - 43,800 hours (1,825 days). Time
can be optionally specified in days or hours providing either
d or D for day and h or H for
hours following the entered time value.
–pol <policy>[,<pol>...]
Specifies virtual volume policies. If an argument is not specified, the option defaults to
stale_ss. Valid policies are as follows:
stale_ss
Specifies that invalid (stale) snapshot volumes are permitted. Failures to update
snapshot data does not affect the write to the base volume. However, the snapshot
is considered invalid.
no_stale_ss
Specifies that stale snapshot volumes are not permitted. A 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 may 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.
NOTE: If the volume is not in any domain, then its retention time cannot exceed
the value of the system's
VVRetentionTimeMax. The default value for the
system's
VVRetentionTimeMax is 14 days. If the volume belongs to a domain,
then its retention time cannot exceed the value of the domain's
VVRetentionTimeMax, if set. The retention time cannot be removed or reduced
once it is set. If the volume has its retention time set, it cannot be removed within
its retention time. If both expiration time and retention time are specified, then
the retention time cannot be longer than the expiration time. This option
requires the 3PAR Virtual Lock License. Contact your local 3PAR Authorized
Service Provider for more information.
