ML570-G1 Intermodule Bus Errors

CA1162156 — Mon, 26 Jul 2004 13:52:07 GMT

ML570-700x2 server crashing with Unrecoverable Intermodule Bus error (Error code 0).
Crashed twice in 2/2004 and twice in 7/2004.
Been running fine for 3 years other than this.

BIOS 12/17/2002, Family 386P20, Type 03
No newer version posted.

PCI bus is:
-S1 = NC3123
-S2 = NC3123
-S3 =
-S4 = SA5302/64 rev 3.54
-S5 =
-S6 = RIBLOE (v1) rev 2.41

Any suggestions?

the IMB bus connects the north bridge (serverworks chipset) to the south bridge and the pci bus. If you are getting errors here, and they are "random" it will be hard to pin it down to "what card caused what" or "what driver walked on what".

You may need to update the PSP if you are runing the old 5.x versions originally deployed with the 570G1...

Do you get any other errors reported? NMI, etc?

John,

The IML has entries for the Bus Error, a Post Error, and an ASR for this event.

The EventLog has a CPQASM entry showing an NMI Intermodule Bus Error, code 0x0.

Server is running W2K svr with CSP 6.40.
Will be installing PSP 7.10 this evening.
Diagnostic Partition (F-10) built using CSP 5.20 and never used.

Been running fine for 3 years other than this.

Dear Matthew Lorenz,

Did the replacement of system board resolve our problem?
I Have a ML570 G1 4x700, and i have the same problem (reboots and crashing).
And the only change we did, was to connect it to a Storage trough PCI iSCSI

Plese reply to me.

Thanks
