5.15 Creating the HP Modular Cooling System Configuration File (Optional)
This task is optional. Perform this task only if the hardware configuration includes a water-based
HP Modular Cooling System (MCS) device.
Follow this procedure to create and populate an MCS configuration file called mcs.ini. The
discover command uses the information in this file to discover the MCS devices.
1. Begin this procedure as the root user on the head node.
2. Change to the following directory:
# cd /opt/hptc/mcs/config
3. Copy the MCS template file into a file called mcs.ini:
# cp mcs_template.ini mcs.ini
4. Use the text editor of your choice to populate the mcs.ini file with site-specific MCS device
information. A sample of the mcs.ini file is shown in Example 5-2 (page 91).
The following list describes the parameters in the mcs.ini file:
mcs_units Specifies each MCS device name separated by a comma.
mcs_server_units Specifies the name of each MCS device that controls one or more
service nodes, separated by a comma
name Specifies the name of the MCS device.
ipaddr Specifies the IP address of the MCS device.
location Specifies the cabinet that contains the nodes that are under control
of the MCS device
nodes Defines the range of nodes under control of the MCS device. The
node range is specified in the format node_prefix[n-n].
status Lists the status of the MCS device. Valid values are offline or
online.
Nagios monitors only the MCS devices that are in the online
state. For more information about MCS device status, see
manage_mcs_status(8).
Before you change the device status to online, make sure the
MCS devices are online and operating correctly.
5. Save the changes to the file and exit the text editor.
Example 5-2 Sample mcs.ini File
# mcs.ini file for cluster penguin
