This is the Service Node Plugin, although it does perform a few functions on
|
|
the Management Node.
|
|
It reads the servicenode table for the service node it is running on,
|
|
and run the appropriate
|
|
setup routine for each service that is designated to be setup in the
|
|
servicenode table for this service node. Some functions are only done for
|
|
Linux.
|
|
A few functions are done not based on the servicenode table. For example:
|
|
|
|
on a Linux Service Node
|
|
if site.installloc set
|
|
mounts /install
|
|
if site.installloc not set
|
|
creates /install if needed
|
|
sets up nfs
|
|
exports /install
|
|

=head3 handled_commands
|
|
|
|
If bypassmode then exit
|
|
If xcat daemon reload then exit
|
|
|
|
Check to see if on a Service Node
|
|
If Linux
|
|
Call setupInstallloc
|
|
If this is a service Node
|
|
Read Service Node Table
|
|
For each service returned to be setup
|
|
Call the appropriate setup_service routine
|
|
else if on the Management Node
|
|
Do any Management Node setup of services needed
