=head1 confignimsh
|
|
|
|
This sample customization script can be used to automatically configure
|
|
the NIM nimsh (NIM service handler). It will also configure NIMSH to
|
|
use OpenSSL in the NIM environment.
|
|
|
|
It assumes that the openssl software has already been installed on the
|
|
node.
|
|
|
|
This script also assumes that you have run "nimconfig -c" on the NIM
|
|
master for the nodes.
|
|
|
|
This script should only be run on AIX standalone (diskfull) cluster compute
|
|
nodes. It should NOT be run on the xCAT management node, service nodes or
|
|
diskless nodes.
|
|
|
|
Note: This script will also remove the .rhosts file (actually back it up).
|
|
If you don't want it removed then comment out those lines.
