Re: BRMS and Parallel Backup

Don't forget the controller card and if needed IOP. Also hope you have
the correct slots open.

Several months ago I performed a recovery test for a client in the same
situation. We wound up using my tape library to get the job done, but it
was at best a very ugly process.

From the v5r4 manual...

"It may be possible to restore from a parallel save if you are using fewer
devices than the save operation used. However, IBM does not recommend this,
due to the amount of volume switching that you will need to do. IBM also
does not recommend this due to performance reasons. If you are restoring
files with constraints, you must use the same number of devices for the
restore as you used for the save. Restore operations that use fewer drives
should only be used to restore individual objects. Restore operations that
use fewer drives should never be used as part of a system recovery
strategy, or to restore large amounts of data. Whenever possible, the same
number of devices that were used during the save operation should be used
during a restore operation."

Assuming this is a live recovery or that you're trying to test your
plan....I'd be getting a drive shipped out same day :)

I did a parallel backup using 2 tapes …

I want to do a recovery on another system, but it only has 1 (one) tape
drive.

I can’t figure out the options I have to use to get this restore to work
in BRMS ….

Has anyone done this before?
