I recently performed a recovery test with a library manager and one client in our TSM test environment. The test environment is a scaled down version of a production environment with a library manager and a library client at one site and a second library client at another site. The recovery worked just as you suspect: I recovered the library manager first and then used the recovered library manager to support recovery of the library client. We used to use a commercial hot site to recover a TSM server with an IBM 3494 tape library. We had to reconfigure the recovered server to use the TS3500 library supplied by the hot site. I think you could just as well reconfigure each of your library clients to use a non-shared tape library. If you do this you will need to update the device configuration files to match the recovery site tape infrastructure before starting the database restores and subsequently update the TSM databases to match the recovery site tape infrastructure. If the hot site provides SCSI libraries the device configuration file updates will include adding records showing the storage slot element numbers for tape volumes.
