Resolution
Resolution Steps

1) Configuration

Sun Fire[TM] 280R
Host Bus Adaptor (HBA) QLogic QLA10162 (PN 375-3057)
Sun StorEdge[TM] 3310 SCSI Array

2) Verify software/firmware

Sun StorEdge 3310 SCSI Array firmware is 3.25W (minimum requirement)
Driver "qus" is to 112697-04 for Solaris[TM] 8 Operating System, 112706-03 for Solaris[TM] 9 Operating System (minimum requirement)

3) Verify hardware

If the problem is persistent after controller firmware and patch verification.

Given the error message:

               Oct  7 17:27:39 calvados    f/w initiated BDR fails

BDR means Bus Device Reset. This error message can occur with a SCSI ATN+/- line cut. So it points to a hardware problem.

Commands that initiate I/O (eg. format, cp, mv, ls, dd, etc.) should return with I/O errors.

Potential sources of hardware problems are:

HBA interface
SCSI cable
SCSI device interface or disk

In this case the SCSI cable between the host and the Sun StorEdge 3310 was defective. To resolve this, replace the aforementioned SCSI cable.
