If your storage solution includes container-copy storage pools that are represented by tape volumes, but you did not configure the disaster recovery manager (DRM) function, you can follow a manual procedure to rotate the tape volumes offsite. By maintaining copies of data in offsite tape volumes, you can restore the data if a disaster occurs onsite.
Procedure
- Check out the storage volume that must be rotated offsite by using the CHECKOUT LIBVOLUME command.
- Update the volume to indicate that it is moved offsite by using the UPDATE
VOLUME command and specifying ACCESS=OFFSITE. Optionally, indicate the offsite location by using the LOCATION
parameter. For example, specify LOCATION=SITE1.
- Reclaim space by taking one of the following actions:
- To reclaim space without protecting the storage pool, run the PROTECT STGPOOL command and specify TYPE=LOCAL and RECLAIM=ONLY.
- To reclaim space while protecting the storage pool, run the PROTECT
STGPOOL command without specifying the RECLAIM parameter.
- Monitor the volume by using the QUERY VOLUME command. If the volume is shown to be unavailable and empty, return the volume onsite and check it into the library by using the CHECKIN LIBVOLUME command.
- Update the volume by using the UPDATE VOLUME command and specifying ACCESS=READWRITE.
