Servicing the HP XC System
This section describes procedures for s ervicing the HP XC system. Fo r more information,
refer to the Service Guide for your system.
The procedures discussed in this section are:
• Adding a node (Section 17 .1)
• Replacing a node (Section 17.2)
• Replacing a system interconnect card i n an XC 600 0 system (Section 17.3)
17.1 Adding a Node
The f ollowing procedure describes how to add one or m ore nodes in the HP XC system.
_________________________ Note _________________________
In th is release, the add ition of a node requires the rediscovery and the
reconfiguration of the entire HP XC system.
1. Log in as superuser on the head node.
2. Note the number of nodes currently on your system. You can determine that number with
the following comm and:
# shownode all | wc -l
3. Prepare the new node hardware as described in the HP XC System Software Hardware
Preparation Guide.
4. Cable the new node (or nodes) into the system. See the HP XC System Software
documentation for your system for more inform ation.
5. Start the automatic discovery of the new node or nodes into your system and ad d them to
the configuration and management database (cmdb).
# cd /opt/hptc/config/sbin
# ./discover --addnode options
See the discover(8) to dete rmine which options are appropriate for your system .
6. Verify that any new nodes h ave been added to your system by run nin g the f ollowing
command and compare it with the result from step 2:
# shownode all | wc -l
7. If the added n ode is of a t ype different from the other nodes and if its disk size does
not match other disks in the H P XC s ystem, modify th e disk size parameters in the
/opt/hptc/systemimager/etc/model.conf file on the head node, where
model refe rs to the model type. See the Release Notes for an y additional information.
8. Run the cluster_config u tility to co nfigu re the nodes and set the imaging
environment:
# ./cluster_config
The cluster_config utility prompts you for key information, as shown here:
