The RETENTIONEXTENSION option specifies the number of days to extend the retention date of a SnapLock volume. This option allows the server to extend the retention date of a SnapLock volume in order to avoid excessive reclamation.
Parameters
- number_of_days
- Specifies the number of days to extend the retention date of a SnapLock volume. The minimum value is 30 days; the maximum value is 9999 days; the default is 365.
- If you specify a value of 0
(zero) for the RETVER parameter
of an archive copy group, the actual value that is used for RETVER is
the value of the option RETENTIONEXTENSION, if one
of the following conditions is also true:
- The destination storage pool for the archive copy group is a SnapLock storage pool.
- The storage pool that is the target for a storage pool migration or of a MOVE DATA or MOVE NODEDATA command is a SnapLock storage pool.
- If a SnapLock volume is the target volume for data from another SnapLock volume and if the remaining retention of the data on the volume is less than the value specified, then the retention date is set using the value specified. Otherwise, the remaining retention of the data is used to set the retention of the volume.
- If a SnapLock volume has entered the reclamation period but the percentage of reclaimable space of the volume has not exceeded the reclamation threshold of the storage pool or the value specified on the THRESHOLD parameter of a RECLAIM STGPOOL command, then the retention date of the SnapLock volume is extended by the amount specified in the RETENTIONEXTENSION option.
Examples
Specify that the retention date is extended by 60 days:
retentionextension 60
