22.6.6 Reconfiguring the Nodes
After editing the platform_vars.ini file and updating the database, you need to reconfigure
the nodes with the new NICs. Use the following procedure:
1. Log in as superuser (root) on the head node.
2. Copy the following files, and any other files that you may have changed:
# pdcp -a -x `hostname` /opt/hptc/config/platform_vars.ini /opt/hptc/config/platform_vars.ini
# pdcp -a -x `hostname` /etc/sysconfig/iptables.proto /etc/sysconfig/iptables.proto
NOTE: If you are using IPv6, remember to copy the ip6tables.proto file also.
# pdcp -a -x `hostname` /etc/sysconfig/ip6tables.proto /etc/sysconfig/ip6tables.proto
3. Run the per-node configuration scripts on the node or nodes that you updated in the CMDB:
# pdsh -w node "/sbin/service nconfig nconfigure"
# pdsh -w node "/sbin/service nconfig nrestart"
Where:
node
Identifies the node or nodes that were updated.
Alternatively, you can reimage the nodes.
For information on imaging nodes and distributing software throughout the system and for
information on the per-node configuration, see Chapter 11 (page 139).
22.6.7 Verifying Success
In addition to the verification steps you took after you edited the platform_vars.ini file and
after you updated the CMDB, you can verify the success of the installation of the NIC card by
verifying the Ethernet Port settings and the Ethernet device, then connecting to the external
network.
Topics include:
• “Verifying the Ethernet Port” (page 288)
• “Verifying the Ethernet Device” (page 288)
• “Testing the Network Connection” (page 288)
