Restricting NIM Client Resource Allocation

NIM provides client machines with the capability of allocating and using any resource in the NIM environment. In some tightly controlled NIM environments, administrators may not want clients to be able to access all resources at all times. To control client-resource allocation, a NIM administrator can use the client_alloc attribute. The restrictions placed by the client_alloc attribute will prevent clients from allocating and using resources, but the NIM master will continue to have the full capability of performing operations on clients.

Note: This task is not currently supported by Web-based System Manager.

From SMIT

NIM client-allocation restrictions can be changed from the SMIT interface by typing the SMIT fast path:

  smit nim_control_alloc

From the Command Line

To restrict all clients from being able to use any resources, set the attribute client_alloc=no on the NIM master:

  nim -o change -a client_alloc=no master

To restrict a particular client from being able to use any resources, set the attribute client_alloc=no on the client:

  nim -o change -a client_alloc=no clientname

To restrict all clients from being able to use a particular resource, set the attribute client_alloc=no on the resource:

  nim -o change -a client_alloc=no resourcename

To lift the restrictions on client-resource allocation, remove the client_alloc attribute by setting it to "yes" for the applicable object:

  nim -o change -a client_alloc=yes master
  nim -o change -a client_alloc=yes clientname
  nim -o change -a client_alloc=yes resourcename
