Been here, seen this, fixed this. Actually we found the solution on the Knowledge base but the answer in the knowledge base is wrong. Sorry, I do not remember the KB solution number, but this is what you have to do.
The default in the Device\Parameters section for the Qlogic card defaults to 0x21. The KB says to change it to at least 131 from 21. What it meant to say is 131 decimal. We set it to 255 or 0xFF and now the SAN agent works fine. The issue is the tape header blocks are read/written as one on the SAN agent apparently differently than the server. The result is what you see. The keyword to set is MaximumSGList. Sorry I cannot remember the HKEY for this. -----Original Message----- From: Joe Cascanette [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 17, 2002 10:03 AM To: [EMAIL PROTECTED] Subject: Re: SAN Problem - TDP for SAP on Windows 2000 Are you using Removable Storage on the Windows2000 server attached to the SAN connected tape unit?, or are you using the drivers supplied by Tivoli (device drivers)?. My server is NT based (not sure about the AIX based) and I am using the Tivoli drivers to connect to my tape storage. I noticed since I needed to disable the Removable Storage service on my Windows 2000 server attached to the SAN to get this to work correctly. Some how the 2 drivers were fighting for control, by disabling this service Tivoli's device drivers had no problem.

TSM 4.2.1.26 Client on Windows 2000 TSM Storageagent 4.2.0.1 on Windows 2000 TDP for SAP on Windows 2000 The Win2000 is connected to the SAN via a Qlogic card. When we start a SAP backup, the tape gets mounted in the correct tape drive, however the following error occurs: (output from dsmsta) ANR0400I Session 6 started for node BSASAP31 (TDP R3 WINNT) (Named Pipe). ANR8337I LTO volume 541ABW mounted in drive DRIVE1 (\\.\Tape2). ANR8938E The adapter for tape drive DRIVE1 (\\.\Tape2) cannot handle the block size needed to use the volume. ANR8468I LTO volume 541ABW dismounted from drive DRIVE1 (\\.\Tape2) in library LIB3584. ANR1401W Mount request denied for volume 541ABW - mount failed. Any ideas as to why it complains about the "block size" and how to fix it?
