Problems accessing psm_data

[Matt Hearn]

I can't believe no one has seen this before, but my searches have turned up NOTHING in the forums!

set_fixed -L is returning the following error:

set_fixed: Cannot list resources in DOWN state due to problems accessing or reading the PSM Resource Data File /var/stm/data/psm_data.

I've tried stopping and starting /sbin/init.d/diagnostic, with no effect other than changing the error (before the restart it was saying "/etc/opt/resmon/lbin/set_fixed: Cannot list resources in DOWN state due to system resource problems").

I checked the actual file, and it's there:

root#> ll /var/stm/data/psm_data
-rw-r--r-- 1 root root 646980 Oct 1 06:23 /var/stm/data/psm_data

I'm not sure what's wrong with it that set_fixed can't read it, but I'm loathe to just go wiping it out without knowing the consequences.

Thanks!

Hi Matt,
What version of EMS OnlineDiags do you have? When did the problem start? If you have an old version, you should consider installing a current one. See http://www.docs.hp.com/en/diag/stm/stm_upd.htm#table for the supported versions.

The problem has been seen if the psm_data file becomes corrupt for some reason. It can be recreated by the following steps:

# /etc/opt/resmon/lbin/monconfig
select (K)ill (disable) monitoring

# /sbin/init.d/diagnostic stop
which stops the diagnostics daemons.

The diaglogd, diagmond and psmctd processes should now be gone. If psmctd
is still running, use "kill -9" to stop it.

Move the psm_data file.

# mv /var/stm/data/psm_data /tmp/psm_data

# /sbin/init.d/diagnostic start

Restart the diagnostic daemons. Ensure that both diaglogd and diagmond are running before proceeding with the next step.

# ps -ef | grep diag

Restart EMS monitoring

# /etc/opt/resmon/lbin/monconfig
select (E)nable Monitoring


It takes a while for the psm_data file to be rebuilt. During that time set_fixed will report this error:

# set_fixed -l
set_fixed: Cannot list resources in DOWN state as PSM Resource Data
File
/var/stm/data/psm_data does not exist.

Once the psm_data file is recreated, set_fixed should be able to recognize all
existing resources and set them back to UP if they are DOWN.
