4.3.6.2 DELETE COMPUTE

This command deletes an existing compute node, removes the instance, home and clusterware from the cluster.

Syntax

DELETE COMPUTE 
WHERE 
   { SRCNAME=host_name [ STEPNAME=step_name ] |
     SRCNAMES=host_names [ STEPNAME=step_name ] }

Arguments

SRCNAME specifies the host name of the guest that you want to remove.

SRCNAMES specifies a comma-separated list host names of the guests that you want to remove.

STEPNAME is used to clean up steps from a failed CREATE COMPUTE command. Specify the name of the individual creation step to be reverted. The values for step_name are:

• ADD_INSTANCE
• EXTEND_DBHOME
• ADD_NODE
• CELL_CONNECTIVITY
• CREATE_USERS

Example 4-14 Deleting a Compute Node - Simple Case
