Hi Tam,

Glad I could be of some use :)

I suspect your issue is caused by staging operations colliding.

How many staging operations do you have automated? If you have the three 
disk-devices, do you have three staging operations configured?

If so, how do you prevent them from colliding, that is one starting while the 
other is running?  Since they are on the same filesystem, there is a good 
chance you will get collisions since usage numbers aren't exact for each 
individual disk volume. So if your staging policy is the same for all three 
volumes notes, unix and linux, you will in theory kick off three stage 
processes at the same time, since all volumes will reach 95% at the same time 
(because it's actually only one file system).

IMO you could do two things:

1. Continue using staging, but repartition the disk with the partition mounted 
on /diskbackup1 into three partitions, mounting these  and making a volume on 
each. This will make sure the watermark settings actually work. You will still 
run the risk of two staging processes fighting over the tape device though.

2. Drop staging and use scheduled cloning instead. It's a bit confusing to 
configure and verify, but it's very reliable and you have full control of 
what's going on.

Thanks Tony, that does help.
Even with 2 drives we have seen contention issues with staging and cloning and 
I am considering doing things differently.

However, as the staging thresholds were around 95%-91% and the retention period 
is 2 months, there were plenty of save sets eligible for staging. Yet some of 
the older larger save sets on the notes volume  were not staged while the most 
recent save sets for other volumes were staged.
