Mark,

There may be nothing wrong with your tape mount exits.  We have run into
similar situations.  Because one of your three disk volumes was read-only,
ADSM was unable to store any data in the disk storage pool.  However,
because the read-only volume was part of the disk storage pool, it is
included when determining whether to trigger migration.  2 of your 3 disk
volumes were 100% utilized.  However, the 3rd was 0% utilized.  The disk
storage pool was therefore 67% utilized - not high enough to trigger
migration!  While the likelihood of a disk volume becoming read-only is low,
it is still a possibility.  Therefore, it would be nice if ADSM migration
were able to handle this situation better - i.e., by somehow figuring out
that a migration is necessary.
