HP Cluster Management Utility CMU Installation Guide with Serviceguard Version 4.0 (May 2009)

Verify the dhcpd listen interface
Ensure that dhcpd is correctly configured to listen on the Ethernet interface connected to the
compute network:
# grep DHCPD_INTERFACE= /etc/sysconfig/dhcpd
# Examples: DHCPD_INTERFACE="eth0"
# DHCPD_INTERFACE="eth0 eth1 eth2 tr0 wlan0"
# DHCPD_INTERFACE="internal0 internal1"
# DHCPD_INTERFACE="id-00:50:fc:e4:f2:65 id-
00:a0:24:cb:cc:5c wlan0"
DHCPD_INTERFACE="eth2"
In this example, dhcpd listens to the interface eth2.
NOTE: You may have to change the default settings if your compute network is not the same as
the site network.
Firewall configuration
If you are using a firewall, please configure it to allow:
• rmi registry traffic (default port 1099)
• X window export (default ports 6000 to 6063)
2-5-2 Install the CMU rpm
CAUTION: The cmu rpm must be installed on one management server
only. As result of this installation, CMU directories and files will be
created on the shared volume and will be accessible from both
management servers under control of Serviceguard
On both management servers, create the mountpoint /opt/cmu.
Check on which of the management servers the shared volume is active:
# vgs -o +tags vgcmu
VG #PV #LV #SN Attr VSize VFree VG Tags
vgcmu 1 1 0 wz--n- 50.00G 30.00G cmumgt1
NOTE: If the vgs command does not return a hostname in the VG Tags field, activate the
volume as described in paragraph 2-3-6 “Configure LVM”.
On that server, mount the shared volume on /opt/cmu:
# mount /dev/vgcmu/lvol0 /opt/cmu
Then install the cmu rpm:
# rpm -ivh cmu-4.0.i686.rpm

A previously saved CMU database can be restored with
/opt/cmu/tools/restoreConfig
Copy the CMU license to /opt/cmu/etc.
Prepare for Serviceguard cmu package
Before configuring and starting the CMU Serviceguard package, the shared volume must be
released. Before doing so, package configuration files coming with the CMU rpm must be
copied to the Serviceguard directory. Those files are located in the directory /opt/cmu/tools:
