We currently run a 4.2.3.2 TSM server under an OS/390 system that also supports several other applications. The system is running out of resources, and we are looking at a number of options for upgrading it or moving part of its workload elsewhere. One of these options is moving the TSM server to an AIX system. There are a number of uncertainties about the operational changes this would entail, one of which is how we would vault the recovery plan files produced by the Disaster Recovery Manager component of TSM. We currently copy the recovery plan to a second file on the tape containing the corresponding database backup. Is it possible to do the same thing with an AIX TSM server? If not, what alternatives are other sites using? There is one major constraint on our choice. When we run disaster recovery tests our network operations staff and our hot site provider's staff usually spend a couple of hours troubleshooting network connections. This is annoying but tolerable if work on rebuilding the TSM server can procede concurrently with the debugging. It would be a disaster if access to the recovery plan file had to wait for successful completion of network troubleshooting.
