question about logs in syslog.log

[yyghp]

I found there were a lot of lines like below in syslog.log. This happends frequently but not everyday. What's that mean ?
And where i can find a detail doc for syslog.log, including detail explanation for any possible message there ?
Thanks !

Hi,


Normally you only see those messages in syslog when you reboot and your system's kernel does a hardware scan.
Do you reboot frequently? It would be strange becouse the syslog is rotated normally when you do.

Gideon

[Alex Glennie]

From the release notes for secure path for 3.0 A
An ioscan results in numerous entries in the syslog.log file. The number is
proportional to the number of claimed LUNs. Operations or applications that
perform periodic ioscans may result in a very large syslog.log files


There's also reference to these in the Secure Path Installation Notes:

Could this be relevant ie the system is connected to a disk array and secure path is installed/configured ?

[T. M. Louah]

If the system was booting at the date/time stamp seen above it is normal to have that ioscan output in syslog, you can check /etc/rc.log for boot date/time stamps to verify if that is true.

I know if I reboot the system, there will be those messages, but I haven't rebooted the system for a long time, and there is no other message(like hardware detection,services down&up) in the syslog around these messages showing system was rebooted by someone else or system itself.
I am the only one who has root access, and I didn't run 'ioscan' and didn't cron any job to run that.
I notice that these messages being added to syslog.log had different time periods.
So, what else ?
Thanks !

[yyghp]

we do use Secure Path... not I didn't schedule ioscan.
And the strange thing is that it didn't happen everday.
so...

Thanks!

[Geno Church_1]

Are you using OVSAM to make SAN configuration changes? If so, then this is normal.

Changes to the
SAN configuration cause notification events to be sent to interested
devices such as FC controllers.

This in turn will cause the HP-UX kernel to re-probe the hardware
connected to the controllers and print this type of message to the syslog.

Geno

[yyghp]

no, i didn't make any config on the system recently. And it happened from 2 months ago, and kept happening at different time on several days, like messages were added today and yesterday...

[yyghp]

any one has suggestion for this situation ?

[Elmar P. Kolkman]

In the above examples the ioscans are happening during office hours. Have you looked at the other messages? For instance grep on a single hardware path to see all instances of that device being seen and you can see at what times this occurs. It might help you find the source of this issue.

(Perhaps some monitoring script or something like that?)

[yyghp]

This happened twice yesterday as shown below:

there is no related messages around that, only have some ftp login log, and those logs appear different time, i don't think this happened due to 'ftp'.
I do schedule performance monitoring:
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/lbin/sa/sa1
but i think that's something like 'sar'. And I schedule this on other machines, no such messages appear on those boxes. So, I don't think the messages due to this. And also, I cron this each 5 mins, but those weird messages appeared at the time unpredicatble.

So, any other suggestion ?

[Geno Church_1]

Like I stated previously, something is happening with the SAN itself which the HP server thinks a change has occured which causes the HPUX kernel to reprobe the hardware. Check to make sure that your EMC or XP 512/1024 (whatever type of disk array you have) isn't haveing some type of issue.

Run a dmesg and post the results from that just to see if there are any messages that might be helpful. Also check the disk array itself to make sure the FC controllers are reporting fine.

Here's the output i got from 'dmesg', please help to check:

And another thing is that SAN is not under my control now. Do you mean someone else changing the config on SAN will make HP-UX generate these messages ?
Thanks !

[Geno Church_1 · Accepted solution]

Dmesg is just reporting the same messages syslog is showing.

Yes, If changes are being made on the SAN then the HPUX kernel reprobes the hardware, which is what you are seeing in syslog and this is normal. Now if a hardware issues exists on the SAn (say a FC controller is acting flaking) then it could cause the same thing to happen. I would check with your SAN folks to make sure all is well with the array. Good Luck!

Thanks Geno, I will check with the SAN guy about this, and I will post the result here later.

[yyghp]

Hi, this problem still continues... :(
I asked the guy who maintains the SAN and disk array, but he said he couldn't find any unusual msg in the device logs.

And today, i noticed that such kind of messages keep adding to syslog.log:

...

Another cue is that our DBA told me that one of the Database crashed and had the error:ora-00471, which is usually because of disk IO errors. But i checked syslog.log and dmesg, no error related to this...
so, any other idea about this ?
Thanks!
