Hi, I've tried everything and am now going round in circles, so I'm at my wits end - please help!
 
I am running BEWS 11d 7170 with an IBM LTO 3 Autoloader (33622LX). These are connected over fibre-channel as part of a SAN fabric. The end of the adamm.log is as follows:

I have read several pieces of advice regarding SCSI terminations and pins etc, but as this is on a fibre-channel SAN, this can't apply.

Also I've checked the VSDLoadTable against the adammlog and it seems to be correct. This is all new SAN hardware and Autoloader, however If this turns out to be a problem with the Autoloader, then at least I can proceed, but I need to know where the fault lies once and for all.

 

If I can provide anymore info, please let me know. Any help is greatly appreciated.

 

Many thanks.
