Scheduling Space Reclamation
During space reclamation, the DXi6900 deletes unneeded tags from the blockpool to free up disk space.
Schedule space reclamation regularly to make sure there is enough disk space to store data.
Caution:Because space reclamation can affect system performance, avoid running space
reclamation during known backup periods.
Note:For more information about space reclamation, see Space Reclamation on page 363.
To configure a schedule for space reclamation:
1. On the Schedulerpage, add or edit an event in the SpaceReclamation row (see Scheduler on page
279).
2. Specify when and how often the event reoccurs (see Scheduler on page 279).
Caution:For correct system operation, space reclamation must be run at regular intervals (at least
once a week).You can schedule space reclamation to occur daily or weekly but not monthly or
yearly. Also, recurrence is required.
3. Click Apply.
