SCSI Reset errors on a shared bus

[Trevor Darby_1]

I have 2 x rp2470 with 1 x A5838A quad card in each, the card is in port 2. Running HPUX 11.11 The ports are set as follows
Server 1
0/4/0/0/4/0 SCSI ID 7 TERM off Speed no Limit
0/4/0/0/4/1 SCSI ID 6 TERM off Speed no Limit

Server 2
0/4/0/0/4/0 SCSI ID 5 TERM off Speed no Limit
0/4/0/0/4/1 SCSI ID 4 TERM off Speed no Limit

These cards are attached to a SC10 using in-line terminators. The SC10 is set up in Split bus mode.

When the server has booted up and I can login, in the syslog.log I get the following
Server 1
SCSI reset lbolt bus 5
repeated about 12 times
Server 2
SCSI reset lbolt bus 7
repeated about 12 times

I have replaced the controllers on both servers ,cables and even moved disks around.
This servers are going to be Service Guard later.
I've run out of ideas!!!!

Trevor,

Please post an ioscan -fn from both servers along with the exact SCSI posted to the message buffer (dmesg).

Best regards...
Dietmar.

Trevor,

Are you using SCSI Cables with InLine Terminators? (A5668A)?

The cables are required in this environment.

Thanks for the replies.

I solved the problem.

I re-seated the SC10 controllers, and the controllers on all the servers. One of the Ultra cards failed on Server 2.

Replaced card and no SCSI reset errors

Many thanks

Trev.
