Hi..
Thanks a lot for your help alan and selden...
As per your suggestions I tried a full report from uerf and I found the
following sequence of events occuring repeatedly leading to a SCSI bus
reset..
It would be a great help if you could tell me what might be going wrong
here? are so many SCSI Bus resets normal? any suggestions on debugging
this problem are welcome..
Thanks everyone for bearing with me..
