Hi,

You have set an option called MAXFILE=some MB in disk storage. pool, so when
the individual file size is greater that that it will automatically move to
the primary tape pool.


You can increase the size of this option if you want all files to go to disk
storage pool

      Now I've noticed sometimes when I backup a file which is considered
large compared to others it goes right to tape. Here's my situation. I have
a SUN system which has an Oracle database on it. When it backup the normal
O/S files it backsup right to disk perfect real quick. Now when it hits a
DBF which is only: "12 meg" mind you, it hangs there and says: "waiting for
mount of offline media....". Now there's plenty of room in the storage
pool, migration doesn't need to run, there's like 200 gig in the disk
stgpool free and the copy group is set for it to go right to disk. Now it's
just not on Oracle DBF files sometimes it's on other application
files..etc. It's like if  a file is over a certain size regardless of the
current disk storage pool utilization percentage it will still mount a tape
and backup to tape?. Any ideas?. Is there something I'm missing? It's a
problem because I do a backup for this client and I see there's more then
enough disk storage pool space freed but not enough tape drives in the time
they want it ran. No big deal I figure because I have more then enough disk
space. WRONG, I kick the backup off and it still trys to mount a tape?????.
Any ideas would be appreciated thanks!.
