HP Insight Control for Linux 6.0 Release Notes

the mdadm and mcleog commands are missing from the /etc/sudoers file on the CMS. As a

result, these commands are not executed properly.

Corrective action: Edit /etc/sudoers on the CMS:

• Add the mdadm and mcleog commands as shown in the first two lines of the example.

• Add MDADM and MCELOG to the end of the nagios ALL entry as shown in this example.

Cmnd_Alias MDADM = /sbin/mdadm

Cmnd_Alias MCELOG = /usr/sbin/mcelog

nagios ALL =

NOPASSWD: CHECKALLSSHKEYS,CHECKSYSLOGALERTS,CHECKSFS,CHECKLSF,

CHECKICMP,CHECKSEL,CHECKSELMON,CHECKLVS,SENSORS,CHECKHOSTS,

RRDSWSETUP,SWITCHPOLLER,SCONTROL,POWEROFF,HPASMCLI,MDADM,MCELOG # HP-HPTC-Nagios

This line is actually a continuation of the previous line; it is shown this way for

clarity.

2.6.12 Nagios services may not work correctly after installing PSP because of incorrect

/opt/hp permissions

If the permissions on the /opt/hp directory are set incorrectly on the CMS or on the management

hubs, the Nagios Nodeinfo, System Event Log, and System Free space services in

Status detail show a status of PENDING and a Status Information of Service is not

scheduled to be checked.

This permissions issue is caused by the PSP installation script (for example, install830.sh)

in PSP 8.31 (and earlier), which changes the permissions on /opt/hp to either 0550 or 0750.

This results in a loss of the Nagios functionality mentioned above because the Nagios plug-ins

run as the nagios user, which no longer has access to the /opt/hp/icelx directory that it

requires.

If you run the Options→IC-Linux→Configure Management Services tool after running the

PSP installation script, the permissions of /opt/hp are restored to at least 0555, as required by

Nagios.

However, if you run the PSP installation script either manually or through the Deploy→Deploy

Drivers, Firmware, and Agents→IC-Linux→Install ProLiant Support Pack (PSP)... tool, after

you have already run Options→IC-Linux→Configure Management Services, then the

permissions on /opt/hp are set to either 0550 or 0750, and the Nagios functions mentioned

above do not work correctly.

Corrective action: You can restore the permissions of /opt/hp to at least 0555 (which is the

minimum required by Nagios) by either of the following methods:

• Run the following command on the CMS and all management hubs as the root user:

# /opt/hptc/config/sbin/check_environment

• Rerun the Options→IC-Linux→Configure Management Services tool, which restores the

permissions automatically.
