3. Invoke the locatenode command again, this time with the --off option to turn off the

Unit Identifier LED when you are done.

3.7 Disabling and Enabling a Node

You can disable one or more nodes in the HP XC system. Disabled nodes are ignored when the

HP XC system is started or stopped with the startsys and stopsys commands, respectively.

The setnode --disable command updates the CMDB to indicate a specified node or a group

of nodes as disabled. In the following example, nodes n2 and n3 are disabled:

# setnode --disable n[2-3]

The shownode disabled command indicates which nodes are currently disabled:

# shownode disabled

The setnode --enable command updates the CMDB to enable a specified node or a group

of nodes. In the following example, nodes n2 and n3 are enabled:

# setnode --enable n[2-3]

The shownode enabled command indicates which nodes are currently enabled.

# shownode enabled

For more information, see setnode(8).
