Hi George,
It works, you have to use mmrecov to move the res and mm over, but
it isn't officially supported, as you noted. Indexes can actually
be rsync'ed over, so you don't have to do them all at once, rather
than having to restore them from tape.
After you migrate, you'll have to manually edit the res (via
nsradmin in offline mode--nsradmin -d /nsr/res/nsrdb, when
networker is shut down) to fix the difference in notifications
between Solaris and Linux.
Thanks, Dave. What are the differences in notifications?
In NetWorker, if you have notifications set so they send email, note
that the path for "mail" and "mailx" differs on Linux and Solaris.
Its /bin/mail on Linux and /usr/bin/mail on Solaris. You can fix that
sort of stuff in the NetWorker Management Console GUI easily enough.
Speaking of the NWMC, if you are thinking about running it under
Linux, think again. Its not supported under Linux.
Licensing will go into grace mode for 15 days, so just make sure
the original box is shut down, or at least networker is first.
Other than that (and a few other details--stinit.def and similar
stuff), just follow the normal steps on "how to replace a networker
server with a new box, using the same hostname as the original one".
We're using an /etc/stinit.def file currently, but that's only on
our Linux snodes since they have the tape libraries. There are no
tape devices on the Solaris primary server. I guess that will all
stay the same then.
Using the same host name as the original seems to be the recommended
approach. I've heard it eliminates a lot of headaches. Would be
easier, though, from a logistics perspective to use a different host
name, but that might create a lot of additional work on the backup
side to change everything, I'm sure.
This depends on how you have your clients set up. We modify each
client's NetWorker start up file and /nsr/res/servers files to point
to the name of our NetWorker server. If you change your NetWorker
server's name, you need to reflect that change on each client, which
can be a major project if you have a lot of clients in your data zone.
You will also need to re-register your licenses. Also, if you change
names and IP addresses on your NetWorker server, you need to contact
EMC to re-register your licenses.
