CPU Upgrade

[Mark Burts]

Upgrading D230 to D270/2, original firmware 36.48, upgraded to 38.40, installed new power supply, and new D270/2 CPU. System panics on HPUX (vmunix) boot, error meassage FLT B800 ccio driver not found in kernel. Tryed to downgrade firmware to 38.46 (D220/230)to install original CPU, firmware installation fails. Any suggestions, starting recovery procedure for installing critical files only.

Problem Description

Why does my system, patched with PHKL_11327
and PHNE_11611 experiencing continual panics
that produce the following message?

interrupt type 15, pcsq.pcoq = 0.2aec08, isr.ior =
0.2c
vtlan1_lq_eoc_proc+210

Configuration Info

Operating System - HP-UX
Version - 10.20
Hardware System - HP 9000
Series - K460

Solution

After further investigation of this system,
the following errors were also noted:

inet_clts:ok
inet_cots:ok
btlan1: Initializing 10/100BASE-T card at 10/16/8.......
btlan1: ERROR: Can't read Config. Enable Register.

It is recommended that you replace the system's 100BT card to resolve this issue.

Before upgrading you should have added the cciio driver to your /stand/system file and built a new kernel with htis driver installed.
You will have to go back to the D220/30 config, rebuild the kernel, then redo you hardware upgrade.
I think you may not have to downgrade the firmware to reboot to your old hardware config.

The major difference in the architecture of these two CPU boards is the way how the GSC bus is generated. In the Dx20/x30 provides the PA7300LC processor the GSC bus as central bus. In a Dx50/Dx60/Dx70/Dx80 has the processor a runway bus interface and a runwaybus-to-GSC bus converter (U-turn) is located on the CPU board. The U-turn needs the ccio driver.
To make a long story short: downgrade the system back to a D230, include the ccio driver to the kernel and upgrade it again to a D270.
