vmunix msgs in syslog

Hi,

I am getting heaps of msgs like the following in syslog on one particular HPUX system. Sometimes repeating every 5mins or so. What do they mean and where are they coming from? I feel a bit stupid asking this, but there it is. :)

Re: vmunix msgs in syslog

The messages are being logged by kernel i.e. vmunix for hsx device having those H/W paths.

The H/W paths through HBA are pointing towards the EVA LUN. For each LUN there would be 4 paths as you can see in the messages. These messages could appear if a LUNs is presented to the host from CV-EVA and SP installed. If the SP is already installed , then it seems that the logging is enabled in SP.
You can check up the logging using command
#spmgr log
There should en entry for syslog and that why you see those messages in syslog file.

By the way, Which version of SP and type of EVA you have?

Re: vmunix msgs in syslog

thanks Sameer,

EVA5000, HPUX 11.11, Secure Path 3.0f.0f

I see that syslog logging is enabled so that makes sense, but why is SP producing these msgs? Some sort of scan going on?

Re: vmunix msgs in syslog

Hi Greg ,

Please check your dmesg, it looks like u have some problem with this perticular virtual disk presented to this server from your EVA.

As u say it is comming every 5 min then check any link problem with your fiber link .

If u can post output of your dmesg command & some last 10 mails of root then i will be able to help u.

Re: vmunix msgs in syslog

If you see syslog, there would be such entries during system bootup where kernel make scan of all attached devices.

Hence something is happening which is making kernel to scan those devices again and again.

Is it giving error to all LUNs presented to this host? Any recent history of failure , problems etc with EVA??

Moreover you need to check for any errors in syslog and demsg . Check the HBA , FC cable , SAN switch. I suspect more likely the problem with a EVA disk from a Vdisk.
Check the EVA disks physically as well.

I would say ,eventhough SP logging is enabled , SP won't give these error directly.

Re: vmunix msgs in syslog

thanks all.
Very wierd. Messages stopped being produced on Friday night for unknown reason. System running fine and EVA's are fine. Monitoring for reoccurrence.
