NIM Client definitions

One day i needed to setup some partitions as NIM clients to let them (and me) make use and take advantage of the NIM power.

 

NIM Client definition 

On the NIM Master:

Make sure that the master can resolve the client name , otherwise nim operations will fail.

So we have to ensure that dns or local /etc/hosts file configuration allow the client name resolution.

Now we can define the client through SMITTY :

 

Smitty nim / Manage Machines / Define a machine

 

On the NIM Client we will :

Make sure that the client can resolve the master name , otherwise any nim operations will fail.

If name resoltion is ok , we can start the operation at the client side:

 

niminit -a name=<client name> -a master=<master name> , 

startsrc -t shell 

 

At this point the environment is configured an it works, but it is not secure because it rely on rsh to do the magic.

We can improve the situation setting up the nimclient to use nimsh or , even better , nimsh over ssl .

So let's instruct the client by typing: 

 

nimclient -C (nimsh)

or

nimclient -c (nimsh secure)

 

To complete the work we must stop r* services 

stopsrc -t shell

and start nimsh

startsrc -s nimsh
