About this task
Complete the following procedure if output from the lshealth -r CLI command
contains a line similar to the following:
SCM ERROR SCM system has found some errors
Note: This procedure involves analyzing various logs depending on the errors
displayed by the initial SCM error log.
Procedure
1. If an error is displayed, run the lshealth -i SCM command to show the details
of the component with the error. SCM is a component, that monitors other
components. Ensure to note the details shown by the Message and Value
columns.
2. To know the error code, run the lslog command or open the graphical user
interface (GUI) Eventlog page.
3. Compare the results returned by lslog command with lshealth -i SCM
command. This procedure helps you in mapping the error. If you are not able
to link the lshealth -i SCM output with the lslog output, continue to the next
step.
4. Open the CNSCM log located at /var/log/cnlog/cnscm for the file module that
reported the error.
5. Review the error entries around the listed time stamp and then check the log
for issues that seem related that occurred before the listed time stamp. For
example, you might find GPFS-related issues appearing earlier and later, too.
6. Review the log entries and try to match the entries with the lslog output. If
you are not able to match the entries, continue to the next step.
7. Based on the log entries, check the appropriate corresponding log. If the issue
appeared to be related to GPFS, for example, you could look for the root cause
in /var/adm/ras/mmfs.log.
8. If the log entries do not help resolve the error, contact the next level of support.
