Re: kernel: aacraid: Host adapter reset request. SCSI hang ?

Hello all,

I have a small update: we've pulled out the root disk, of the server, 
and plugged it into an external disk array, which we connected to the 
server.  Server got reinstalled, and I'm trying to simulate the problem 
again, by generating high load and I/O on the data disks (still 
connected to PERC3/Di controller).  So far, the server is up and running 
since yesterday morning (longest I've achieved so far), and still 
running smoothly.

Has anyone else tried this before, and if yes, how long did it last 
before the server crashed?  Btw, I am currently not using any new 
tst-driver or any special settings in kernel.

More info will follow, sooner or later (if it crashes).
