Solaris

Hi

I have solaris 10 running on a cPCI CPU card, the uname -a info is:

SunOS 5.10 Generic_120011-14 sun4u sparc sun4u

In addition, it has two Ethernet connections and a PMC ss7 link card installed.

Occasionally, i got this error message from /var/adm/messages file

unix: [ID 257829 kern.warning] WARNING: interrupt 0x7c0 at level 15 not serviced

Sometimes system panic after this message

What does this mean?? thks

seems like they all started with cpu panic

WARNING: interrupt level 12 not serviced

according some bug reports in sunsolve interrupt Level "N" may refers to a device, like Level 5 indicates that the problem is probably that of a cdrom drive

Level 15 from reading several sunsolve reports seems to indicate that Interrupt Level 15 related to volume manager or some "disk" controller related problem.

Do you have any jbod or san storage connected recently to your box? Or installed any patches/firmware related to it in recent memory?

Maybe you should also escalate to sun.

Do you have any coredumps under /var/crash/`hostname` directory?
what else do you see in the messages file? model of your system? any RSC logs?

Thanks for your advices,

The system is connected with a NAS server, the hardware connection was not changed since they were in solaris 8.

There are many coredumps under /var/crash/hostname, i've checked through these images by mdb, found CPU status and stack info are different each time, can you tell how can i parse the images of this kind of panic? The system is a cPCI processer card, with 650MHz sparc cpu.

A sample piece of messages around the panic is below:

Pls upload the latest coredumps to SUN for analysis. I believe you have a contract with them. The messages file is not showing much useful information

if memory servers me correct (from last night)... your explorer file won't show anything as well!

only a few times sun has come back to us and said... explorer is showing xyz and you should do xyz to resolve. but yes, send them explorer file.
