Restoring The Host And Library Environment - IBM TS7700 Series User Manual

Restoring the Host and Library Environment

In order to run your applications and access the data in the recovery TS7700, the source host environment
must also be restored. At a minimum, you will need to perform the following general steps:
• Restore the tape management system control data set.
• Restore the DFSMS data catalogs, including the Tape Configuration Data Base (TCDB).
• Define the I/O gen using the library ID of the recovery TS7700.
• Update the library definitions in the SMS Control Data Set (SCDS) with the library IDs for the recovery
TS7700 in the composite and distributed library definition panels.
• Activate the I/O gen and the SCDS.
You may also want to update the library nicknames that are defined through the management interface for
the grid and cluster to match the library names defined to DFSMS. That way, the names shown on the
management interface panels will match those used at the host for the composite and distributed libraries.
To set up the composite name used by the host to be the grid name, select the Grid Identification
Properties item on the Configuration menu. In the panel that displays, enter the composite library name
used by the host into the Grid nickname field. You can optionally provide a description. Likewise, to set up
the distributed name, select the Cluster Identification Properties item on the Configuration menu. In the
panel that displays, enter the composite library name used by the host into the Cluster nickname field. You
can optionally provide a description. The names can be updated at any time.
Note: Remember to insert logical volumes if you are going to be writing data to the recovered TS7700 once
you have re-established the host environment and brought the TS7700 online.
