Hi,
You'll need to delete and recreate the NetWorker changer since serial
numbers will change, before step 3. Probably best to make a copy of
/nsr/res before you do that, so it is easy to go back to the original
VTL without having to recreate the autochanger again.
I'd probably make sure your persistent naming is configured so that
the secondary VTL uses different tape devices names, so that it is
easy to go back to the original configuration. That'll also keep you
from having to delete the original tape drives in NetWorker, meaning
you don't have to remove them from pools, delete them, add the new
ones, and add them to the pools--just the last two steps.

Subject: NetWorker and VTL DR testing
We're testing our new backup environment which is a primary VTL
replicated to a secondary VTL. As part of the testing, we want to
walk through a DR scenario where the primary VTL is
unavailable. Unfortunately, we only have the production NetWorker
server for this testing. Here's what I think we need to do:
1. Remove primary VTL from environment (isolate so that this system
isn't touched during the test)
2. Make the secondary VTL the primary (we're reviewing our procedure
for this with the VTL vendor)
3. Test restoring data from existing VTL tapes
4. Test backing up data to blank VTL tape
5. Test restoring newly backed up data
6. Relabel test tape so that is blank (that is, get NetWorker back
to original state)
7. Disconnect VTL (original secondary) and restore the original configuration
8. Reconnect original primary VTL to NetWorker server
9. Finish rebuilding secondary VTL as necessary
Is this correct? Are there any other steps that need to be
done? I'm particularly concerned with how the NetWorker server will
react to swapping the VTLs.
Thanks.
Teresa
