Copy export recovery
Use this page to test a copy export recovery or perform an actual copy export recovery on the TS7700.
If the cluster does not possess a physical library, the Copy export recovery page is not visible on the TS7700 web interface.
Copy export permits the export of all virtual volumes and the virtual volume database to physical
volumes, which can then be ejected and saved as part of a data retention policy for disaster
recovery. You can also use this function to test system recovery.
Note: For a detailed summary of
copy export recovery including preparation for and performing a copy export recovery, refer to the
following white paper https://www.ibm.com/support/pages/node/6355037.
Before attempting a
copy export, ensure all physical media to be used in the recovery is inserted. During a copy export
recovery, all current virtual and physical volumes are erased from the database and virtual volumes
are erased from the cache. Do not attempt a copy export operation on a cluster where current data is
to be saved. Support Matrix

installed

Important: In a grid configuration, each TS7700 is considered a separate
source. This means that only the physical volume exported from a source TS7700 can be used for recovery of
that source. Physical volumes exported from more than one source TS7700 in a grid configuration cannot
be combined to use in recovery. Recovery can only occur to a single cluster configuration; the
TS7700 used for recovery
must be configured as Cluster 0.
- Secondary Copies
- If you create a new secondary copy, the original secondary copy is deleted since it becomes inactive data. For instance, if you modify constructs for virtual volumes that have already been exported and the virtual volumes are remounted, a new secondary physical volume is created. The original physical volume copy is deleted without overwriting the virtual volumes. When the copy export operation is rerun, the new, active version of the data is used.
The following fields and options are presented to the user to assist
in testing recovery or performing a recovery.
- Volser of physical stacked volume for Recovery Test
- The physical volume from which the copy export recovery attempts to recover the database.
- Disaster Recovery Test Mode
- This option determines whether a Copy Export Recovery is run as a test or to recover a machine that has suffered a disaster. If this box contains a checkmark (default status), the Copy Export Recovery runs as a test. If the box is cleared, the recovery process runs in "normal" mode, as when recovering from an actual disaster.
- Erase all existing virtual volumes during recovery
- This check box is shown if virtual volume or physical volume data is present in the database. A Copy Export Recovery operation will erase any existing data. No option exists to retain existing data while performing the recovery. You must check this check box to proceed with the Copy Export Recovery operation.
- Submit
- Click this button to initiate the Copy Export Recovery operation.
- Confirm Submission of Copy Export Recovery
- You are asked to confirm your decision to initiate a Copy Export
Recovery option. Click OK to continue with the Copy Export
Recovery operation. Click Cancel to abandon the Copy Export
Recovery operation and return to the Copy Export Recovery page.
- Password
- Your user password. If you checked the Erase all existing virtual volumes during recovery check box, the confirmation message includes the Password field. You must provide a password to erase all current data and proceed with the operation.
