Missing netdiag1 driver, /dev/netlog, /dev/nettrace files

Jack C. Mahaffey — Thu, 12 Aug 2004 12:18:36 GMT

Did some patching today. Cannot see the netdiag1 driver in sam or the /dev/netlog or /dev/nettrace files.

Using 11.0 HP-UX.

Any suggestions?

Got following error in rc.log.

10715 NOTE: Executing insf to create new telnet ptys in /dev/pts.
10716 nettl : Warning: The device file /dev/nettrace and/or /dev/netlog is
10717 not present or cannot be opened. Continuing with the
10718 initialization of Trace/Log facility. Kernel tracing/logging
10719 cannot be done. Ensure that the kernel configuration includes
10720 the Trace/Log device driver netdiag1 and that the Trace/Log
10721 device files exist and are readable.

Here's contents of swlist -l product | grep EMS

I see there are two versions of EMS-Core, do I swremove the A.03.10 version?

Here's contents of swagent on swinstall.

It looks like I need to find and reload the following:

"EMS-DiskMonitor.DISKMON-RUN, fr=A.03.20,v=HP".
"EMS-MIBMonitor.MIBMON-RUN, fr=A.03.20,v=HP".
"EMS-RdbmsMon.RDBMSMON-RUN,fr=A.03.20,v=HP".

7270 NOTE: The fileset "PHSS_26871.EMS-GUI,r=1.0" is already installed.
7271 If you wish to reinstall this fileset, change the "reinstall"
7272 option to "true".

7274 NOTE: The patch fileset "PHSS_26871.DISKMON-RUN,r=1.0" may only be

7276 specification for this base fileset is

7278 no fileset on the target or selected from the source which
7279 matches this specification, fileset
7280 "PHSS_26871.DISKMON-RUN,r=1.0" will be excluded.

I compared the B7609BA product to another system and it looks like I need to replace the A.03.10 version with A.03.20.

Gonna search hp for B7609BA for download.

Installed the missing components for A.20. Driver and device files still do not exist.

Some questions:

1 Should I swremove the A.10 version. I'm asumming everything will still be ok.
2 How do I add the netdiag1 driver?
3 How do I recreate the nettrace and netlog device files?

Hi Jack,

I've never heard of this problem before, but here are the steps I'd take:

1. Install PHNE_29231

This is the latest patch for the network tracing and logging facility. Hopefully this patch will ensure that the netdiag1 driver is installed.

2. Recreate the missing device files

# mknod /dev/netlog c 46 1
# mknod /dev/nettrace c 46 0

Hopefully these steps will restore your network tracing and logging capabilities.

Good luck,

Dave

Dave, thanks a whole bunch for the speedy reply. I'll try it in the next 10 minutes. I got about an hour before I got to release the server.

swinstall indicated software is configured... Ran mknod and now rebooting. I suspect it will still fail because the driver netdiag1 is not showing up in sam. How do I add it to sam?

Is it safe to remove the A.10 version of EMS?

Re: Missing netdiag1 driver, /dev/netlog, /dev/nettrace files

Dave Olker — Thu, 12 Aug 2004 15:05:52 GMT

Hi Jack,

Make sure "netdiag1" is listed in the /stand/system file in the "Drivers and Subsystems" section. Looking at my 11.0 system:

# more /stand/system
* Drivers and Subsystems

DlkmDrv
GSCtoPCI
PCItoPCI
arp
asio0
asp
autofsc
btlan3
btlan6
c720
cb
cdfs
clone
core
diag0
diag1
diag2
dlkm
dlpi
dmem
echo
fc
fc_arp
fcgsc
fcgsc_lan
ffs
hpstreams
inet
ip
klog
lasi
lba
ldterm
lv
lvm
maclan
netdiag1 <<<<<<<<<<<<<<
netqa
nfs_client
...

If you don't have netdiag1 in your /stand/system file then I'd try manually adding it with vi. Then rebuild your kernel with:

# mk_kernel -o /stand/vmunix

Then reboot the new kernel and see if it works.

Regards,

Dave

Hi Jack,

Sorry, I'm not sure why you're wanting to mess with EMS in the first place. Are you having an EMS-related problem that you believe is caused by a conflict of EMS code?

I'll give it a shot by updating the /stand/system file...

Jack C. Mahaffey — Thu, 12 Aug 2004 15:12:35 GMT

Dave, just wanted to clear up the remaining error message on bootup. I get to do patch maintenance on the server only one to two times a year.

Jack C. Mahaffey — Thu, 12 Aug 2004 15:25:07 GMT

/stand/system already has the netdiag1 entry.
I'm runing the mk_kernel now and rebooting.

Here's the current output from rc.log from the last reboot. I just changed owner and permissions to match another server.

376 Start network tracing and logging daemon
377 Output from "/sbin/rc2.d/S300nettl start":

Checked sam on another server that isn't having the problem and it doesn't show the netdiag1 in the list of drivers either in the gui. It is in the /stand/system file however. This must be a case where the driver is not included in the GUI.

I'll post the results of my reboot shortly.

Hi Jack,

What are the perms & ownership on those devices?

should both be:

crw-r--r-- bin bin

Dave, thanks a bunch. Is it still ok to swremove the A.01 Version?

Dave Olker — Thu, 12 Aug 2004 16:15:05 GMT

Hi Jack,

I apologize - I don't know anything about EMS, so I hesitate to advise you on removing versions of a product that I know nothing about.

As you discovered, PHSS_26871 is looking for a base version of these filesets:

EMS-DiskMonitor.DISKMON-RUN, fr=A.03.20,v=HP
EMS-MIBMonitor.MIBMON-RUN, fr=A.03.20,v=HP
EMS-RdbmsMon.RDBMSMON-RUN,fr=A.03.20,v=HP

none of which exist on your system currently.

I guess my questions would be:

How did you install EMS on this system initially? Did you install A.03.20?

What does this command return:

# swlist -l fileset | grep EMS

Do you have EMS installed on mutliple systems? Does the above swlist command return different fileset information for different systems?

Regards,

Dave

Looks like its only missing the following two now:

EMS-RdbmsMon.RDBMSMON-RUN,fr=A.03.20,v=HP
