13.2.2 New Visualization Nodes Do Not Exceed the Maximum Number of Nodes
Supplied to the cluster_prep Command
Follow this procedure if you added visualization nodes to the existing system and the number
of new nodes does not exceed the maximum node number you set during the initial
cluster_prep process.
Because the number of new nodes does not exceed the previous maximum number of nodes,
you do not need to run cluster_prep command again, but you do have to discover the new
nodes.
1. Follow the instructions in Section 2.4.2 (page 48) to install the SVA software.
2. Reset the database:
# /opt/hptc/sbin/reset_db
3. Start with Chapter 4 (page 63), and follow the instructions to run the discover and
cluster_config utilities.
4. Set all new nodes to network boot:
# setnode --resync --all
5. See Section 6.7 (page 117), and follow the instructions to run the startsys utility to reimage
all nodes.
6. Perform the system verification tasks in Chapter 8 (page 129).
13.2.3 Graphics Cards Have Been Added to Existing Nodes
Follow this procedure to install and configure SVA on an existing HP XC system to which you
added graphics cards to existing nodes that are capable of visualization. Because you did not
add to the total number of nodes, you do not have to rerun the cluster_prep or discover
utilities.
1. Follow the instructions in Section 2.4.2 (page 48) to install the SVA software.
2. Reset the database:
# /opt/hptc/sbin/reset_db
3. Follow the instructions in Section 6.2 (page 100) to run the cluster_config utility.
Accept all default answers and be sure to configure the external Ethernet devices on the
SVA nodes.
4. See Section 6.7 (page 117), and follow the instructions to run the startsys utility to reimage
all nodes.
5. Perform the system verification tasks in Chapter 8 (page 129).
