I did experience the same problem at a DR 3 years ago.  What we found out
was our Daily Process was not working properly.  The BACKUP STGPOOL was not
finishing to successful completion.  Also, did a RESTORE STGPOOL COPYPOOL.
I usually run the restore a couple of months b4 DR to help sync things up.
Last year there was no tapes to restore.  As long as our daily process
continues to complete successfully our DR will work good.

Dear all

I've been running TSM for four years or so. When we use BACKUP STGPOOL to
copy a primary storage pool to a copy storage pool, I have relied on the
fact that a successful completion means I have two copies of all my data.

I've just discovered that a number of my files don't have a second copy.
For a large number of volumes (more than 10 per server) Q CONTENT xxxxxx
COPIED=NO comes back details of the files but BACKUP STGPOOL (with or
without PREVIEW=YES) tells me there is no data to be copied.

Some of these files were backed up from the client months (years?) ago.
Some are active, some are inactive.

I discovered this when testing my DR procedures. I updated the status of
all my primary storage pool volumes to be DESTROYED and ran a RESTORE
STGPOOL PREVIEW=YES. I was shocked at the number of 'ANR1256W Volume XXXXXX
contains files that could not be restored' messages that resulted.

I've logged a PMR but wondered if anybody else had experienced similar. It
kind of blows a big hole in my DR plans.

For info, we are running TSM Server 4.2.1.15 on Windows.

Thanks
