"scsi_if_isr" error message... Little help?

[Shane Travis]

Hi... back with my tales of woe from HP-UX 8.0 boxes. I've got a machine (fortunately on the local testbed this time and not on site) that, after a reboot in November, just refused to come back up.

(The reboot, btw, was to change the IP address and a few other things, and I'm 99.995% sure that it was not the cause, since it's done by scripts which a) I wrote, and b) I've run 150 times before with no problem.)

I'm receiving the following messages on screen when the system is starting up, after which it hangs forever. I've done my homework -- looked in documentation, searched this site, used Google, used Dejanews -- and can find no mention anywhere of this error message. I"ve also tried opening up the box and reseating all the connections, to no effect.

If anyone has seen it before, or has any ideas on what to do to fix it, the help would be greatly appreciated.

Pardon me for asking the basics, but assuming you have the support CD loaded.......

When you do on ODE MAPPER do all your devices show up as available? I've seen it where a drive that is shut down never comes back up due to a bad motor.

[Rita C Workman]

Forgive me my rambling...
I tend to go along with Mr. Coury...
I know that ISR (Intermediate Session Router) lends to hardware failure. And in your message it was trying to go through the startups...got to fsclean and I notice the /dev/dsk is invalid..no address. /etc/fsclean is a link to /usr/sbin/fsclean. So I'm thinking (again with Mr. Coury) that something has happened to the disk (or at least some part) of that disk, so it could not perform the rest of the general startups...fsclean, fschk and it died.
Usually, I have seen panics showing isr.ior that mention HPMC for memory problems. But I think your actual disk device is the problem...
Curious, if this is on your root disk...is your root disk mirrored? Can you try booting off the mirror?

Like I said...I sometimes tend to ramble..just my 2cents.

This probably is not of much help, but
"panic: scsi_if_isr: Not connected with SCSI"

The "scsi_if_isr" portion means that the SCSI InterFace device driver's ISR (interrupt service routine) found a problem.

I'm guessing that a hardware interrupt was detected and passed off to the various system interrupt handlers. When the SCSI driver got hold of the interrupt notification the driver determined that the SCSI controller was not the source of the interrupt, and it caused the panic.

This could mean that your SCSI controller hardware is acting abnormally, or some other hardware on your system is generating interrupts that are somehow being sent down the chain and are being intercepted by the SCSI driver.

In response to Paul Courry:
Perhaps I should have been more clear than the one passing reference at the top... I'm dealing with HP-UX 8.0. Back to the dark days of 1992 here. The O/S did come on CDs, but that's about it, and in order to install (or reinstall) it I need to find an external CD ROM device. No internals here.

That said, I'm not finding any sort of Support CD in my stores for this system, and so no ODE mapper. Sure would make things easier...


In response to Rita Workman:
> I know that ISR (Intermediate Session Router)

Who's right on the meaning of this acronym... you, or Mr. Lampi?

> /etc/fsclean is a link to /usr/sbin/fsclean.

No offense, but there is no /usr/sbin on an 8.0 machine...

And no, no mirrot on the boot disk. That said, it is what I'm figuring the problem may be, and am working on finding a replacement for it. Hard to find disks that *small* nowadays though... 8.0 can't handle disk sizes of over 1 Gig.


In respose to Michael Lampi:
Yeah, not a lot in your message about what to *do* about it, but I do appreciate the infodump on what the eror messages may mean. Every little bit of information helps.

Thanks all for the responses, and if anyone thinks of anything else, please let me know.

Tim,

No offense taken....I don't go back to an 8 system. When I started here the oldest was a 9. something and I quickly cold imaged it up to 11.

As for who's right on the acronym...guess it depends on which document your reading at the time. But it does appear your problem is hardware related.

So my best of wishes to you....I'm sure the others would agree, wish we could have done more.
