anyone knows this behaviour?

we're running 6.1.1 on F740 w/ an direct attached ATL L200 (1 Drive) Backupserver is an E450 w/ Solaris 8 and NBU 3.4 DC.

NBU always sets the drive in the L200 down. Also i'm upping the drive it lasts bout 30 sec. till the drive is down again.

no ndmp backup is possible. a started dump from the filer is working fine. the nbu config seems ok. authorization works, robtest and tldtest from the nbu-server on the L200 also works.

could this be a problem cause of missing /etc/dumpdates? who can read an "ndmpd debug 50"-output?

thx h
