Symptoms
A poor SCSI negotiation speed occurs when a Sun StorEdge[TM] S1 array is
attached to a Sun Fire[TM] V440 server's onboard SCSI external port.

You can check the negotiation speed with the following:

# prtpicl -v | grep sync
:no-dma-interrupt-sync
:target0-sync-speed        320000
:target1-sync-speed        320000
:target2-sync-speed        320000
:target0-sync-speed        40000
:target1-sync-speed        40000
:target2-sync-speed        40000
In the example, the second lot of disks are running at 40000, but the
onboard SCSI controller in the Sun Fire V440 server is an Ultra320 SCSI,
and in the Sun StorEdge S1 array is an Ultra160 SCSI.  Therefore, the
minimum speed should be 16000.
Also, the following messages appear during boot:
NOTICE: mpt1: fault detected in device; service still available
NOTICE: mpt1: Connected command timeout for Target 0
WARNING: /pci@1f,700000/scsi@2,1 (mpt1):
Target 0 reducing sync. transfer rate

Resolution
Add the following to the /kernel/drv/mpt.conf file and then reboot:

   name="mpt" parent="/pci@1f,700000"
unit-address="2,1"
scsi-options=0x1ff8;
Compare the prtpicl output following this change to the prtpic1 output
shown previously:
# prtpicl -v | grep sync
:no-dma-interrupt-sync
:target0-sync-speed        320000
:target1-sync-speed        320000
:target2-sync-speed        320000
:target0-sync-speed        160000
:target1-sync-speed        160000
:target2-sync-speed        160000
You should also use the latest patches for the Sun Fire V440 onboard SCSI
controller:

Solaris 9 Operating System     - 116532
