Comments:
|
|
If refoutput is 1, then the output will be returned as a
|
|
reference to an array for efficiency.
|
|
|
|
If refoutput is 2, then the response hash will be returned
|
|
as output. runxcmd will not parse the request structure, nor
|
|
will it display the error message despite the exit_code setting.
|
|
The caller will need to display the error.
|
|
|
|
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.
|
|
|
|
The caller to the runxcmd is responsible for filename expansion, that
|
|
would have been done if the command was run on the command line.
|
|
For example, the xdcp node1 /tmp/testfile* /tmp command needs to
|
|
have the /tmp/testfile* argument expanded before call xdcp with
|
|
runxcmd. The easy way to do this is to use the perl glob function.
|
|
@files=glob "/tmp/testfile*";

=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
|

|

Returns:
