How much data was supposed to be on volume 000027? If there was only 1 file this
sounds like it could be normal behavior - if the file spanned tape volumes ADSM
would move the piece that was on 000027 and then ask for 000004 to be mounted so
it could move the remainder of the file.

ADSM: 3.1.2.50
AIX: 4.2.1 w/patches
Tape Library: ADIC 224

I wanted to move some data off a tape labeled 000027.  I issued MOVE DATA
000027.  I then issued a Q PRO and the system responded that it was waiting
for tapes 000027 and 000018.  Both tapes were mounted.  After a few minutes,
I saw that tape 000027 unmount so I re-issued Q PRO and here's the output.

adsm> q pro

       2 Move Data            Volume 000027 (storage pool TAPEPOOL), Target

                               Pool TAPEPOOL, Moved Files: 0, Moved Bytes:

                               Unreadable Files: 0, Unreadable Bytes: 0.

                               Current Physical File (bytes): 328,454

                               Waiting for mount of input volume 000004 (8

                               seconds).

                               Current output volume: 000018.

As you can see, ADSM was now waiting for tape 000004!  Now tape 000004 was
mounted and, again, after a few minutes it was unmounted.  I looked in the
actlog and the process for the MOVE DATA 000027 had completed successfully
and the tape was now marked scratch.

Can someone explain this?  Thanks in advance.
