Delete snapshots
You cannot delete snapshots for an existing PN. However, if you
deleted a PN, because you either removed the PN from production or you moved the PN to another HA, you might want to delete all the orphan data associated with that PN. Such orphan data includes:
• PN snapshots
• RN
• RN snapshots
• Self test schedules
However, in the latter case, don’t delete the orphan data without first confirming that backups for the PN are working on the new HA. Moreover, to keep the onQ Appliances in sync, Quorum recommends that you perform this procedure on the HA’s DR Appliances and DR Mirrors.
If you remove orphan data for a PN from the HA—but not from the DR, then later re-enroll that same PN on the same HA, the DR fails to add the future snapshots for this PN thereby compromising disaster recovery.
To delete orphan data:
1. Log on to the HA’s onQ Portal.
2. Go to PROTECTION CONFIG tab > FIND ORPHANS button.
The onQ Portal searches the Repository for orphan data. If onQ Portal doesn’t find any orphan data, the onQ Portal returns a No data found that does not belong to a configured PN message. Otherwise, the onQ Portal prompts you to purge the orphan data that the onQ Portal did find.
3. Select the check box for the PN whose orphan snapshots you want to delete, then click YES.
| Warning: You cannot abort a purge after it begins. |
A progress dialog appears, highlighting the number of files waiting to be deleted. This process can take several minutes per snapshot.
4. After the purge completes, repeat
Step 2 to verify that the onQ Portal removed all orphan snapshots.
| Warning: If you delete orphan data for a given PN, Quorum recommends that you do so for both the HA and the DR. If you remove orphan data for a given PN from the HA—but not from the DR, then later re-enroll that same PN on the same HA, the DR fails to add the future snapshots for this PN thereby compromising disaster recovery. |
5. (Recommended) Repeat this process on each DR Appliance and DR Mirror so that all onQ Appliances are in sync.
