Problem booting: DIAGNOSTIC SYSTEM WARNING

Rafael Moran_1 — Thu, 20 Sep 2001 18:47:07 GMT

Hello,

When booting a K360 I obtain the following message:

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.

lv_readvgdats: Could not read VGDA 1 header & trailer from disk H/W path 10/0.3.0 (error = 5)

I don't know what it means excesive errors from I/O subsystem if I just rebooted.
About the 10/0.3.0 disk I checked it once inside the system and everything seems ok.

Anyone can help me please ?

Thank you all

Hi Sachin,

Actually this internal disk is the mirror of the boot disk

HI
Check if the disk is still accessable using ioscan. If this is mirror disk check for lv status (current/stale) in vg00.
#lvdisplay -v /dev/vg00/lvol* |pg

Thanks.
Prashant.

Rafael Moran_1 — Thu, 20 Sep 2001 20:13:09 GMT

Thank you Prashant,

I have checked it but all the lvols are ok, they show current status

Re: Problem booting: DIAGNOSTIC SYSTEM WARNING

Deshpande Prashant — Thu, 20 Sep 2001 20:25:06 GMT

HI
Any errors noted in dmesg or syslog?

Check info in cstm for the disk if possible.

Thanks.
Prashant.

Rafael Moran_1 — Thu, 20 Sep 2001 20:42:28 GMT

Hi Prashant,

The message I wrote on the first message is the one it appears when booting and it is registered on dmesg and syslog.
I also checked with cstm but nothing strange

Thank you

Hi Rafael,

Try to increase the timeout for the disk/pv that is giving you this problem. The default timeout is 30seconds. Increase it to 3 minutes and see if it helps.

pvchange -t 180 pv_path

The maximum timeout can be 5 minutes (300 seconds). Also check and see if any conenction is loose or the termination is missing.

Hope this helps.

thanks

Hi Raphael,

Did you try increasing the timeout and did it seem to fix the problem?

Here is another thread which looks very similar(error numbers are different though)
http://forums.itrc.hp.com/cm/QuestionAnswer/1,1150,0xbb86663ce855d511abcd0090277a778c,00.html

It would be interesting if Mark could tell us if it indeed was a bad disk and replacing that fixed the problem.

-Regards
Ramesh
