Hi

Thank you for your reply.

I don't see how it can write the tail of a backup to a tape when there is only 
one drive and it is used to receive the stage job.
None of the savesets have other flag than 'c'

But, there is an issue with the raid controller on the backupserver and I will 
wait for it to be resolved to see if it may somehow be the casue.

Thanks
Eivind

There was some changes in 7.6 that changed the way AFTD volumes work.
Previously, if your AFTD filled up during a save, the save would wait for space 
to become available in that volume.
Now, AFTDs are handled like a tape volume, and will continue the saveset on 
another volume.

Maybe your AFTD ran out of space, and the tail of the saveset was written to a 
tape?
So when you stage that ssid, it would need to read the start of the saveset 
from AFDT, and the end of it from tape - because staging acts on savesets, not 
chunks of savesets in a volume.

You could identify any continued savesets with 'mminfo -av', the 'c' flag in 
the output is complete, h is head (start of saveset), m is middle and t is tail.
Those last three flags all indicate that more than one volume is needed for 
that saveset.

Or, something like this will grab a list of all ssids on your AFTD volume, and 
then check what volume types and names contain each saveset

$ mminfo -av -q 'volume=your_aftd_volume_name' -r ssid | perl -ne 
'chomp;system("mminfo -q ssid=$_ -xc, -r ssid,type,volume|grep -v ssid");'
(but won't work in a windows environment unless you've got perl/grep available, 
there's probably ways to do the same thing from windows with different tools 
though)

Regards,
Josh
