Re: Stacked backups Was: Virtualizing Tape VIOS vs IBM 1

[Kirk Goins <kirkgoins@xxxxxxxxx>]

Timing takes a little practice... I know how each of my backups take with a
little fudge factor tossed. Since all my partitions are IBM  and I have
Object Connect setup ( you could do this other ways ) I do the following.
I have a dataarea defined on each partition. When backup A finishes I first
vary off the drive and via a CL tell the HMC to Move the SAS Adapter to
partition #B.  Then I set a value in that dataarea and SAVRSTOBJ to the
next partition where a program is checking the dataarea for the OK to
start.. I then set the dataarea back to a value for You Can't Start Yet and
end partition A.
Repeat until al the backups are completed.  With the new Power8 I am going
to switch to virtualized tapes drives on a single SAS card owned by VIOS so
I won't have to worry about have the HMC move the card and I can run both
drives a the same time with a single card fro 2 partitions.
