Troubleshooting ITO in a ServiceGuard Environment
Troubleshooting ITO in a ServiceGuard
Environment
This chapter describes some of the problems you might encounter when
working with ITO SG packages, and provides some specific
troubleshooting hints. For more general troubleshooting information, see
the troubleshooting section in the Managing MC/ServiceGuard manual.
ITO SG Logfiles
MC/ServiceGuard and the ITO SG package use the following two logfiles:
❏ /var/adm/syslog/syslog.log
This logfile contains general error messages from MC/ServiceGuard.
❏ /etc/cmcluster/OpC/OpC.cntl.log
This contains the output of the ITO SG package during startup and
shutdown.
If you do encounter problems with the ITO SG package, make sure that
you check the contents of both files.
Maintenance Notes for ITO/NNM and
MC/ServiceGuard
The ITO MC/SG package can be set to maintenance mode to avoid a
switch-over of the package when ITO is stopped. This is neoclassical
when you run a backup or if a patch has to be installed. The shared disk
and may the database must be available in this case. You can enable
maintenance mode by touching the file
/tmp/mainNNM . The monitor
scripts nnm.mon and ito.mon does not trigger a package switch-over if
the file /tmp/mainNNM exists
