HP XC System Software Administration Guide Version 3.1

NOTE: The crash utility is designed to examine an uncompressed kernel image (a vmlinux file) that
was compiled with the compiler's -g option so that it can be debugged. Consider editing the kernel
Makefile to add the -g option to the CFLAGS line.
7.9.1 Installing Netdump and Crash
Two RPMs for Netdump are available:
• The netdump client runs on the nodes to be monitored.
• The netdump-server runs on the nodes that can receive the kernel dumps over the internal network.
Use the following procedure to install the Netdump on the HP XC system:
1. Log in as superuser (root) on the head node.
2. Use the rpm command to install the appropriate RPMs:
rpm -ihv netdump-rev_number.platform.rpm
rpm -ihv netdump-server-rev_number.platform.rpm
where:
rev_number Is the revision number of the software. At the time of this publication, the revision
number is 0.7.14-4.
platform Is the platform code.
Use x86_64 for CP4000 systems.
Use ia64 for CP6000 systems.
3. Use the rpm command to install the crash software:
rpm -ihv crash-rev_number.platform
The rev_number and platform parameters have the same meaning as in step 2. At the time of this
publication, the revision number is 4.0-2.17.1hp.
4. Distribute the software to the appropriate nodes in the HP XC system. See Chapter 10 (page 129) for
more information.
7.9.2 Configuring Netdump
This section describes how to configure the netdump-server and the netdump client.
7.9.2.1 Configuring the Netdump Client
Use the following procedure to configure the netdump client:
1. Log in as superuser (root) on the head node.
2. Use the text editor of your choice to edit the /etc/sysconfig/netdump file to change the following
line:
# NETDUMPADDR=
to the following:
NETDUMPADDR=IP_address
where IP_address is the IP address of the netdump-server node.
Be sure to save the file and exit the editor.
3. Use the following command to allow the netdump utility ssh key access to the netdump-server
node:
# service netdump propagate
NOTE: This command performs the following:
