Our last full blown DR exercise was done with 6.0 MP5, and our next one will be done with 6.5.3.1. My master is on AIX 5.3 TL9.
I replicate my NBU server's operating system to another disk subsystem and boot the copy on somewhat similar hardware in a remote location. Everything works fine in this respect. Naturally, I must remove old definitions for network adapters and tape drives and re-detect them, but that always works as advertised. One of the first things that I do is remove any entries to SERVER and MEDIA_SERVER for my media servers in the bp.conf and DEVICE_HOST and KNOWN in the vm.conf, so that the master server isn't trying to contact them for anything. Media servers are not brought back in the DR exercise. They simply exist "back home" for speed using the SSO option. They all contain a considerable amount of data, and trying to push that data over the network while everything else is backing up doesn't make sense. For DR, everything is a restore, so pushing that data back over the network is fine, since it is a one-time-good-deal. We did a mini-test in August where I restored one Windows server, but noticed that with 6.5.3.1, everything was slow, but I wrote it off to the fact that the servers that are media servers at home, and are not media servers in DR, didn't exist during the mini-test, and the master server was still trying to communicate with them, because they still existed in the EMM database. But now I am looking at it a little more suspiciously, thinking it may be a 6.5 thing, instead of a "lack of hosts altogether" thing. My quick answer in August was "It was trying to communicate with servers that weren't there and just timing out, but in January (when the big test happens) it will get "connection refused" because the same hosts will exist but not be media servers. Is my logic flawed, or should I be looking to decommission the media servers in January as part of the test? If I have to decommission the media servers, it is looking like an additional 2 hours due to the media movement I have to do in the database to actually remove the media servers. It takes about 3 seconds a tape to move media, and I have a bunch of tapes to move logically, even though those tapes won't be touched at DR (I restore from duplicated copies). Thoughts?
