Solaris Troubleshooting : Data Gathering for LDOM issue troubleshooting

Data Gathering for LDOM troubleshooting IssuesThis post will help you to gather necessary information required to troubleshoot a LDOM issue. And this post doesn’t cover the actual problem resolution found during the data analysis.

Data Gathering for Troubleshooting LDOM issues

SMF(Service Management Facility) logs for the LDom related services on the primary domain

/var/svc/log/ldoms-ldmd:default.log
/var/svc/log/ldoms-vntsd:default.log
/var/svc/log/ldoms-agents:default.log
/var/opt/SUNWldm/ldom-db.xml

SMF(Service Management Facility) and logs for the LDom related services on the Guest LDom

/var/svc/log/platform-sun4v-drd:default.log
/var/svc/log/ldoms-agents:default.log

If the ldmd daemon dumps core, the core file will be ‘/var/opt/SUNWldm/core’ unless the customer has used coreadm to control the core file location and/or name.
The message ‘Invalid response’ from ldm usually means that the ldmd daemon has dumped core so the core file should be collected in that case

For Issues related to Domain Console ,  please collect the console log of the domain.

A console log of the commands(Solaris[TM] or ALOM/ILOM) used and errors will be help for the investigation.    Starting from LDom 3.0, console log is collected at /var/log/vntsd/*/* ( minimum Solaris 11 on primary domain )
 
# ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL NORM UPTIME
primary active -n-cv- UART 8 24G 0.2% 0.2% 12d 11h 1m
guest01 active -n—- 4001 10 2304M 0.1% 0.1% 12d 7h 22m

Console logs on live system:

# ls -l /var/log/vntsd/*/*
-rw——- 1 root root 2812386 Sep 18 10:38 /var/log/vntsd/guest01/console-log
-rw——- 1 root root 289847 Sep 16 12:00 /var/log/vntsd/guest02/console-log
-rw——- 1 root root 653980 Sep 27 08:31 /var/log/vntsd/guest03/console-log
-rw——- 1 root root 15458337 Sep 30 11:57 /var/log/vntsd/sec01/console-log
 
 
Console logs in explorer ( collected with option ‘ldom’ in earlier explorer rev’s, per default in newer explorer rev’s )
 
% cd {explorer_directory}
% ls ./ldom/log/vntsd/guest01/con*
./ldom/log/vntsd/guest01/console-log
./ldom/log/vntsd/guest01/console-log.0

I have started unixadminschool.com ( aka gurkulindia.com) in 2009 as my own personal reference blog, and later sometime i have realized that my leanings might be helpful for other unixadmins if I manage my knowledge-base in more user friendly format. And the result is today's' unixadminschool.com. You can connect me at - https://www.linkedin.com/in/unixadminschool/
