[Networker] 7.0 and ADIC Scalar 1000 with 2 Crossroads FCR250 and DLT8000's and Brocade SAN
2004-11-10 01:32:19
We have a SAN (Dual fabric with Brocade 12000's, 3850's, and 3800's)
NetWorker Server is Sun Ultra60 with Emulex LP8000 HBA.
Tape library is an ADIC Scalar 1000 with 7 DLT8000 tape-drives and 2 FCR250
FibreChannelRouters(Crossroads) each with 1 FC connection and 2 SCSI busses
behind.
FCR#1
Bus-0 Tape Library Robotics only item on the bus
Bus-1 2 DLT8000 Tape drives
FCR#2
Bus-0 2 DLT8000 Tape Drives
Bus-1 3 DLT8000 Tape Drives
The symptom we see is ultimately that a drive will not "unload"
Nov 8 21:18:54 nw3 unix: NOTICE: lpfc1:039:Cannot issue FCP command
Data: 0 0 0 0
Nov 8 21:18:55 nw3 unix: NOTICE: lus_intr(5.0.0): transport failure
(tran_err)
And yet running the mt command (mt -f /dev/rmt/2cbn offline) seems to work
about every time.
Why does mt work but NetWorker not work ?
thanks in advance for any advice - John
