first attempt to ignite rx6600 fails with panic. second attempt OK

[Charles Slivkoff]

This week, I've been installing several new rx6600 servers using an image from a similar rx6600. In each case, the load fails on the first attempt with a panic, but the second attempt succeeds OK.

I found one report of the same panic message

panic: post_hndlr(): Unresolved kernel interruption

in a thread which was due to a bad CPU.

I'm concerned, though, that I've had the same experience on three different rx6600's.

I'm attaching a capture of the console which contains the panic and register dump.

Anyone have any ideas?

Charles,

The release notes for Ignite-UX Version C.7.4.157 contain the following notice:

Ignite-UX version C.7.4.157 contains this single functional change from
the C.7.4.155 version:

- The B.11.23 and B.11.31 IINSTALL install kernel sasd (SAS) device
driver was changed to not download host bus adapter (HBA) firmware.
This functional change makes SAS HBA firmware management simpler
since booting the Ignite-UX install kernel will no longer result in
possible firmware update or downdate.

- Fixes for the following Change Request:

* QXCR1000745232. This fix helps avoid an HP-UX system panic that
may happen on systems with SAS adapters during system boot in the
middle of install before software configuration. Note that the
install of an older HP-UX release on a system that has newer SAS
adapter firmware may trigger a panic even with this fix. Although
the new install kernel does not update or downdate the firmware
version, the final system kernel (/stand/vmunix) may downdate the
firmware version due to the installed sasd driver. This could
happen if the system has had a newer HP-UX release installed. If
the system panic does occur, software configuration and the rest of
the install process should complete normally after the extra
reboot. The SAS driver CR QXCR1000472961 provides information
about this general issue not related to install.

- Notes related to known problems with this release:

There are no new known problems.

From the output you attached, you do have SAS devices attached, so this is likely the problem. You can download Ignite-UX C.7.4.157 via docs.hp.com/en/IUX.
