HP Insight Control for Linux 6.1 Release Notes

2.7.4 pdsh command fails for the CMS if the CMS host name is not fully qualified
The CMS host name attribute in the SIM database might change between its fully qualified name
(for example, venus.example.com) and its simple name (for example, venus).
This might occur if the PSP components required by Insight Control for Linux are not installed
or configured on the CMS.
Corrective action: If the pdsh command fails for the CMS, replace the fully qualified name in
the /opt/hptc/pdsh/nodes file (venus.example.com) with the simple name (venus).
2.7.5 Nagios nsca daemon might fail to start on the CMS
The nsca daemon might fail to start on the CMS.
Every time you run Options→Configure Insight Control for Linux Management Services,
verify that the nsca daemon is running on the CMS:
# /etc/init.d/nagios status_nsca
If the nsca daemon is not running, enter the following command to start it:
# /etc/init.d/nagios start_nsca
2.7.6 Nagios nrpe daemon might fail to start on the CMS
The nrpe daemon might fail to start on the CMS.
Every time you run Options→Configure Insight Control for Linux Management Services,
verify that the nrpe daemon is running on the CMS:
# ps auxww | grep nrpe
If nrpe is not running, enter the following command to start it:
# /etc/init.d/nagios start_nrpe
2.7.7 Nagios may generate WARNING "data is stale" messages if RRDs become
corrupted
On rare occasions, the RRDs, where Nagios stores metric and sensor data, might become corrupted.
If the RRD file sizes for a specific metric (for example, load average) are not identical for all the
managed systems then the RRDs are corrupted.
For example, in the output below, note that two of the three RRD files are of equal size (71104),
but the other file is not (35944). Note also that the shownode metrics load command reports
data for only one of the three managed systems.
# ls -lt /hptc_cluster/rrd/avenrun/

Corrective action: Follow this procedure on your CMS to move the RRD directory aside and
rerun the Configure Management Services task, which re-creates the /hptc_cluster/rrd
directory and reconfigures the Insight Control for Linux management services:
1. Move the /hptc_cluster/rrd directory to another file name:
# mv -Rf /hptc_cluster/rrd /hptc_cluster/rrd-save
You may choose to delete this directory instead.
2. Rerun the Configure Management Services task:
Options→IC-Linux→Configure Management Services
