Diagnostic System Warning

Mike_112 — Fri, 18 May 2001 21:05:54 GMT

When booting my HPUX 11.0 box I get a warning that comes up during the Startup checks. The system hangs when the warning comes up. This happens when at the Configure HP Fibre Channel interfaces check. the entire error is:
Diagnostic System Warning
The diagnostic logging facility has started receiving excessive errors from the I/O subsystem. I/O error entries will be lost until the cause of the excessive I/O logging is corrected......If teh Diaglogd daemon is not active, use the daemon startup command in stm to start it....if the Diaglogd daemon is active, use the logtool utility in stm to determine which I/O substem is logging excessive errors.

I can get around in UNIX but not well enough to get this fixed. I have run fsck on the filesystems and cleaned them but can not get past the above error.

Thanks
Mike

Hi Mike,

that smells like a hardware failure of some sort.
As the message indicates you probably need to run stm to determine what is broken.
But because you need to get some parts replaced then anyways and need to pace a call to hp you might as well ask them to help you run the diagnostics.

As you saw in the message, there must be something wrong at that moment.
Run stm and get into logtool to decide where you're getting excessive errors.
It'll show you the number of IO errors per each IO subsystem with figures.

mike,
install the patch for fibre channel interface
(sorry not sure about the patch name)

Thanks, I've found the patch. But because as I said the system locks at the point of the error and I can not log in normally, is it possible to install a patch while logged in single user mode? If so are there any special things I need to know to do this?

Thanks

Hi Mike, the short answer to your question is no. We need to have the Swagent Daemon running (swagentd). A better workaround might be to
temporarily turn off fiber channel. Install the patch; re-enable fiber channel.

I don't know your configuration but this should be close.

1) Boot single-user. /sbin/mount /usr
/sbin/mount /var
2) cd /etc/rc.config.d
3) vi fc_td_conf (this is probably your FC config file but if not it should be close)
4) set FC_TD_START=0 (again you may be a little different) and save the file
5)
/sbin/umount /var
/sbin/umount /usr
sync; sync; sync
6) Now reboot normally and the FC should be bypassed so that you can run swinstall.

Obviously you need to set FC_TD_START=1 but I would wait until I came up ok after the patch install.

Hope this gets you out of the ditch, Clay

Thanks for the help Clay. I was able to get to step #2, I don't have the fc_td_conf file but i did find a file, hpfcgsc_lanconfg for configuring the Fiber channel interfaces. The only line there was; HPFCGSC_INTERFACE_NAME[0]=
Should this not have lan0 after the eguals sign? would this be the corredt file for placing the START=0 line you mentioned?

Thanks again

You also may want to try going into single-user mode, then ,at the prompt, type:

# init 1

This will put you into Run level 1 that if I'm not mistaken should have the swagent running. If not start it manually, then install the patch and reboot.
