7.10.2 Configuring Netdump
This section describes how to configure the netdump-server and the netdump client.
7.10.2.1 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:
cat /etc/sysconfig/netdump_id_dsa.pub | \
ssh netdump@$NETDUMPADDR cat '>>' /var/crash/.ssh/authorized_keys2
Be prepared to supply the superuser password on the netdump-server node.
If you do not want to set a password for the netdump user, enter the following command:
cat /etc/sysconfig/netdump_id_dsa.pub | \
ssh root@$NETDUMPADDR cat '>>' /var/crash/.ssh/authorized_keys2
7.10.2.2 Configuring the Netdump-Server
The configuration for netdump-server is performed on the netdump server node during
installation. No further configuration is required.
7.10.3 Starting Netdump
Use the following procedure to start Netdump on the HP XC system:
1. Log in as superuser (root) on the head node.
2. Enter the following command to start the netdump-server service on those nodes that
receive the kernel dump data:
# pdsh -w server_list "service netdump-server start"
where server_list is a list of nodes that receive the kernel dump data over the internal
network.
3. Enter the following command to start the netdump service on those nodes to be monitored:
# pdsh -w mon_list "service netdump start"
where mon_list is a list of nodes that will be monitored and will send their kernel dump
data over the internal network in the event of a crash.
