Reusing a volume without destroying it

You might have a SnapVault for NetBackup volume that is no longer used as an archive, which you want to reuse for another purpose without destroying and re-creating it.

Considerations

Steps

1. Expire all of the backups to the storage unit configured as this volume using the NetBackup application. For more information, see the VERITAS NetBackup System Administrator’s Guide.
   Note: The NetBackup application might show that all the backups have been expired, but the NearStore storage system might be in the process of destroying data from the volume. You might not be able to destroy the volume until all the file data is completely destroyed from the volume.

2. Delete the NetBackup storage unit configured for this volume using the NetBackup application. For more information, see the VERITAS NetBackup System Administrator's Guide.
3. Check if there are any qtrees remaining on the volume by entering the following command: qtree status volume_name

   volume_name is the name of the volume.

4. Remove every qtree shown, other than the .nbu_image_data qtree, by entering the following command for each qtree: snapvault stop -f qtree_path
5. Remove the .nbu_image_data qtree by entering the following command: snapvault stop -f /vol/volume_name/.nbu_image_data
6. Verify if deduplication is enabled for a volume by entering the following command: sis status /vol/volume_name
7. End any deduplication activity on the volume by entering the following command: sis off /vol/volume_name
8. Reset the schedule for automatic Snapshot copy creation by entering the following command: snap sched volume_name

   Example

   snap sched vol1 0 2 6@8,12,16,20

9. To ensure that space is reserved for Snapshot copies, reset the snap reserve settings for the volume:snap reserve volume_name [percent_reserve]

   percent_reserve is the percentage of space you want to reserve for the Snapshot copies.

   Example

   snap reserve vol1 20
