 Hi,

 Is it posible to migrate data from disk to tape whitout modify the
high and
low parameters  of the storage pool?

AFAIK, no.

 upd stg diskpool hig=0 low=0
 upd stg diskpool hig=90 low=75

 This method doesn't work in a trigger because it's necessary a short
interval
 of time between the first and second command to start the migration.

 I must use two tiggers to be able to perform the migration.

Or, in our case, scripted from unix.

 Other problem, it's while the parameters in the storage pool are
fixed to
zero and if in this moment a client makes a backup, it'll write to the
tape,
not to disk array.
 Are there any solution to this problem? I'ld prefer the clients write
the
data to disk array, always.

You sure? I'm fairly positive that our two servers (4.2.1.13 and
5.1.6.5)
don't do this - we have our thresholds set to zero for some time, and
there's usually still backups running (30+ GB NT servers over 64 Kbit,
glad we're using TSM...).
