Hello,

I have problem with lanfree backups (they are not completly lanfree in
some cases). I submited it as PMR 12204 in Tivoli.

When I have multiple management classes in active policy set and size of
first file to back up was smaller than TXNBYTELIMIT (default is 2000k),
then this buffer was written trough LAN. Rest of files were written trough
SAN (to the same storage pool). This in not a case when only one
management class is defined.


Problem is that in this behavior backup process needs one more mountpoint
than I would expect... Could somebody please test/confirm/disprove
described behavior?



In following example I have lowered TXNBYTELIMIT to 300. You can see
ANS1114I message twice:
