Isolating Software Problems; Operating-System Checks; Csm Checks - IBM eserver Cluster 1350 Installation And Service Manual

Isolating software problems

Use the following information to isolate and resolve software problems.

Operating-system checks

Use the following information to resolve operating-system checks:
Node non-responsive
If the node does not respond to ping or the serial console, and there are no
relevant entries in the syslog or hardware logs, refer to the applicable Linux
documentation that came with your software to continue with the problem resolution
process.
Adapter device driver not configured
If the device driver is not configured, and there are no adapter hardware problems
reported, refer to the applicable Linux documentation that came with your software
and continue with the problem resolution process.

CSM checks

Use the following information to resolve CSM checks:
Events not logged or actions not taken
Using the ERRM command line interface, monitor the AnyNodeProcessorsIdleTime
condition on specific managed nodes with the LogEventsAnyTime response while
causing arm and rearm events. If arm and rearm events are not observed at the
management server, this is configuration or network problem. Refer to the
applicable documentation that came with CSM and complete the problem resolution
process.
Differences in node lists
Output from the command CT_CONTACT=<ManagedNodeName> lsrsrc
IBM.[Host|FileSystem] when run on the management node is not the same as
when run on the managed node. This is configuration or network problem, refer to
the applicable documentation that came with CSM and complete the problem
resolution process.
netstat output incomplete
The command netstat -an | grep rmc on the management server does not show
ESTABLISHED TCP connections for each managed node that is currently turned
on. This is configuration or network problem, refer to the applicable documentation
that came with CSM and complete the problem resolution process.
RMC not running
The command lssrc -ls ctrmc shows that RMC is not running on the
management server. Refer to the applicable documentation that came with CSM
and complete the problem resolution process.
lsrsrc reports errors
The command lsrsrc -ab IBM.[Host|FileSystem]' which checks that HostRM and
FSRM will run on the management server reports errors. Refer to the applicable
documentation that came with CSM and complete the problem resolution process.
lsaudrec reports errors
The command lsaudrec which checks that AuditRM will run on the management
server reports errors. Refer to the applicable documentation that came with CSM
and complete the problem resolution process.
