HP XC System Software Release Notes for Version 2.1

5
Configuration Notes
This chapter contains information about configuring the system. Notes that
describe additional configuration tasks are mandatory and have been organized
chronologically. Perform these tasks in the sequence presented in this chapter.
The XC system configuration procedure is documented in Chapter 4 of the HP
XC System Software Installation Guide.
5.1 Tasks to Perform After Running the cluster_config Utility
Perform the tasks described in this section after you run the cluster_config
utility, before the golden system image is replicated to all nodes.
5.1.1 Required Task: Update Nagios Status
Nagios is started before any client nodes are imaged and started. From time to
time, Nagios may fail to update the status of the display. This problem can be
identified by pending services displayed on the Nagios Web page or by services that
appear to have not updated recently as shown by the time stamp.
To correct this problem, restart Nagios on the head node:
# service nagios restart
If the Nagios status is not updated, do the following:
# service nagios stop
# rm -f /opt/hptc/nagios/var/status.sav
# service nagios start
The previous command sequence removes the cached copy of the service states and
requires Nagios to acquire all status from the various services.
5.2 Hang May Be Encountered When Logging In To the Head
Node
When logging in to the GNOME desktop environment on the head node, you may
encounter a blue screen that shows nothing but the mouse pointer. To correct this
hang, you must terminate the gnome-settings-daemon.
To terminate the gnome-settings-daemon, perform the following procedure
from a remote login to the head node:
1. Determine the process ID of the gnome-settings-daemon:
# ps -aef | grep gnome-settings-daemon | grep -v grep
Output will be similar to the following; the process ID of the daemon is
indicated by [PID]:
root [PID] 1 0 11:16 ? 00:00:00
gnome-settings-daemon --oaf-activate-iid=OAFIID:GNOME_SettingsDaemon --
oaf-ior-fd=14
2. Terminate the process ID:
# kill -9 [PID]
