Dear all,

Thanks for all your help. I have solved the problem by replacing the IBM
4_B differential adapter to an Adaptec 2944 UW one. Amazingly it works
perfectly once I plugged it in the system. Again my appreciation to all of
your help.

Christy -
Be sure that you are looking at the drives on the correct port when you
define them in ADSM.
Here is a good way to check:
Go to the control panel, click on SCSi adapters. Click on the adapter that
your library is connected to, for me it is an adaptec card,
click on your library to get the properties and click in the settings tab.
The port should be 01 based on your configuration define in ADSM
of MT0.0.0.1 If the number is different in the settings tab make sure to
update your drive to match it. I.E if the settings tab says
2 in the SCSI port field then update the drive to mt0.0.0.2.


Let us know!

Good luck -
C

     Hi folks,

     I need your help in solving the ADSM backup problem.

     Background story:
     To install ADSM 3.1 on NT Server 4.0 with Service Pack 4 running on
IBM
     Netfinity 5500 and a Magstar MP 3570 attached to PCI SCSI-2
Fast/Wide
     Differential adapter in Netfinity 5500.
     After installation finished and reboot, ADSM server started, device
drive
     ADSMscsi started.
     Increase database, recovery log volume, disk storage pools.
     Under diagnostic found following items:
     TapePeripheral mt0.0.0.1
     MediumChangerPeripheral lb0.1.0.1
     TapePeripheral mt2.0.0.1

     Command used to define the library, dual drives, class and
storagepool:
     >define library autolib libtype=scsi device=lb0.1.0.1
     >define drive autolib autodrive1 device=my0.0.0.1 element=16
     >define drive autolib autodrive2 device=my2.0.0.1 element=17
     >define devclass autoclass devtype=35700 format=3570C
library=autolib
     mountlimit=2
     >define stgpool autopool aotoclass maxscratch=100
     I use the wizard to label libray volume for both magazines and
follwing
     command to check in the library volume
     >checkin libvolume autolib status=scratch search=yes

     Setting on the Magstar MP 3570:
     Library has been configured in Random mode and is running base

     All the above command run successfully. But problem occurs while I
backup
     data on to the tape cartridge. The whole system was hung with the
following
     error:

     ANR8302E I/O erroro on drive AUTODRIVE1 <MT0.0.0.1>
     <OP=WRITE, CC=205, KEY=FF, ASC=FF, ASCQ=FF, SENSE=**NONE**
     Description=SCSI Adapter Failure>. Refer to Appendix B in the
'message'
     manual for recommended action.

     Message in the event viewer in NT:

     The description for Event ID (11) in source (AdsmScsi) could not be
found.
     It contains the followinig insertion string(s):
     \Device\lb0.1.0.1

     The description for Event ID (11) in source (AdsmScsi) could not be
found.
     It contains the followinig insertion string(s):
     \Device\mt0.0.0.1


     Action:
     I installed Magstar MP 3570 driver under NT tape device and backup
     successfully onto a tape cartridge on Magstar MP 3570 via NT's
native
     backup. I guess it eliminates the possibility of adapter failure.

     Any clues? I tried to install service pack 3 for NT 4.0 and also the
fix 3.1.2.20 for ADSM V3R1, but no improvement has made. Have I miss a step
during the installation? Or ADSM for NT simply doesn't work with Magstar MP
3570 and DLT 7337? Please advise.
