IMHO it shows all the errors with the scsi system. It's on http://laokoon.in-berlin.de/~beutin/syslog.gz If i can increase the debug level i will do it if it helps! I cannot imagine a cabling problem, because the drives are in a hot swap backplane and i changed the places of the drives (but having the IBM drive every time as the first drive). Or is it possible to have a bad cable from the board to the backplane, beeing ok for the U160 IBM drive but not for a U360 drive? I'm using the SCSI cable coming with the board, but i will try another next time i've access to the machine. Do You think, it could help to set the controller maximum to U160 on the expected SCSI-IDs for the fujitsu drives? Do You have any idea where to find the firmware an an update tool for fujitsu drives? Any hints or help welcome! Thanks for reading! -tb -- Thomas Beutin tb@laokoon.IN-Berlin.DE Beam me up, Scotty.
