Do not use the scalar string input for xdsh unless you are running

a simple single-word command. When building your request hash,

the entire command string xdsh runs needs to be a single entry

in the arg array.

=head3 StartService
|
|
Supports AIX and Linux as long as the service is registered with
|
|
lssrc or startsrc.
|
|
Used by the service node plugin (AAsn.pm) to start requested services.
|
|
Checks to see if the input service is already started. If it is started
|
|
it stops and starts the service. Otherwise
|
|
it just starts the service.
|
|
Note we are using the system command on the start of the services to see
|
|
the output when the xcatd is started on Service Nodes. Do not change this.
|
|
Arguments:
|
|
servicename
|
|
force flag
|
|
Returns:
|
|
0 - ok
|
|
1 - could not start the service
|
|
Globals:

|

|
|
Error:
