SCSI HBA driver error messages

Alice Daniel — Wed, 18 Jan 2006 10:58:53 GMT

Does anyone know what the following SCSI errors mean? Also, where can I get information about decoding the ITPSA1 driver error messages?

Tru64 OS version 4.0f, Firmware rev 6.8-13, AlphaServer ES40, HBA is QLOGIC ISP1040B/V2 with firmware revision 5.57.

I am attached via SCSI extenders to a custom piece of hardware (target 2). I get the following messages and the SCSI bus resets:

ITPSA1: SCSI error for target 2 sist0=0x4
ccb_status = 0x6
ITPSA1: DIP Intr, istat=0x81, dstat-0x90
ITPSA1" SCSI bus was reset.

I have the latest patches installed from following patch kits.
- DUV40FB18-C0067302-14158-ES-20020429 OSF440
- DUV40FB18AS0007-20020102 OSF440
- DUV40FB22AS0008-20030730 OSF440

Hi,

what kind of hardware is it? Is it on the supported list?

greetings,

Michael

Neff data acquisition hardware with a SCSI interface. The hardware is some distance from the alpha server, so we have SCSI extenders (APCON) between the server and Neff.

Alice,

The sist0 register has the value 0x4, this means that there was an unexpected disconnect.
ccb_status 0x6 indicates Bus/Device problems.

So, there seems to be something shaky in the SCSI chain to the device with target 2.

Hope this helps
