You have migration delay set to 1 day. However migration continue is set
to yes.
It may be that the server is migrating down automatically files that
have not satisfied the migration delay time?
I haven't used this much as I tend to keep migration day at 0 days.

Subject: [ADSM-L] Tapes getting opened and closed hundreds of times
during disk-bac kup
Hello All,
I have been working on this a while, and I am at my wit's end:
Backing up (on 5.3 server) to a stgpool of disk. There are NO copy
stgpools defined for the disk, although I did try that at one time.
As any client backs up, along with writing to the disk stgpool, it also
opens and closes an LTO tape in my main tape pool hundreds of
times...open close...open close...open close...
Further symptoms: The backup process is apparently writing as it should
to disk stgpool BUT also to my "Next Storage Pool", SL500. I see NO
reason for this behavior.
If Tivoli cannot mount a tape in the SL500, the client backup will not
continue...it will just wait for media. Any help would be greatly
appreciated. I have even restarted the Tivoli server process to reload
the configs, but no change.
Any help/suggestions are greatly appreciated! :)
