Cluster Management and Administration 

To remove a user account from one or more cluster nodes, you can either use 
the AIX 

rmuser

 command on one cluster node after the other, or use the 

C-SPOC 

cl_rmuser

 command or the C-SPOC Remove a User from the 

Cluster SMIT screen. The 

cl_rmuser

 command executes the AIX 

rmuser

 

command on all cluster nodes.

In order to manage a number of similar users as a single entity, AIX provides 
the administrator with the group concept. Members of one group share the 
same permissions, the same attributes and limits, and so on. 

Commands for managing group accounts are just like the user managing 
commands very much alike to the native AIX commands. The restrictions on 
NIS are just the same as for users, and therefore are not explained here in 
detail.

For more detailed information, please refer to Chapter 12 of the 

HACMP for 

AIX, Version 4.3: Administration Guide, SC23-4279. 

Because these commands are running and executing while distributed 
amongst the cluster, it could happen that something doesn’t work exactly like 
it should. The C-SPOC utility, therefore, maintains a log on the initiating node. 
It can be found under 

/tmp/cspoc.log.

Note that the initiating node doesn’t have to be the same in all cases, so the 
log file might be present on different cluster nodes, and doesn’t contain the 
same data. 

The system removes the user account but does not remove the home 
directory or any files owned by the user. These files are only accessible to 
users with root authority or by the group in which the user was a member.
