=head3 runxcmd
Run the given xCAT cmd and return the output in an array.
Alternately, if this function is used in a scalar context, the output
is joined into a single string with newlines separating the lines.
Arguments:
command - string with following format:
<xCAT cmd name> <comma-delimited nodelist> <cmd args>
where the xCAT cmd name is as reqistered in the plugins,
the nodelist is already flattened and verified
the remainder of the string is passed as args.
The nodelist may be set to the string "NO_NODE_RANGE" to
not pass in any nodes to the command.
OR
command - request hash
reference to xCAT daemon sub_req routine
exitcode
reference to output
Returns:
see below
Globals:
$::RUNCMD_RC , $::CALLBACK
Error:
Cannot determine error code. If ERROR data set in response
hash, $::RUNCMD_RC will be set to 1.
Normally, if there is an error running the cmd,it will display the
error and exit with the cmds exit code, unless exitcode
is given one of the following values:
0: display error msg, DO NOT exit on error, but set
$::RUNCMD_RC to the exit code.
-1: DO NOT display error msg and DO NOT exit on error, but set
$::RUNCMD_RC to the exit code.
-2: DO the default behavior (display error msg and exit with cmds
exit code.
number > 0: Display error msg and exit with the given code
Example:
my $outref = xCAT::Utils->runxcmd($cmd,$sub_req, -2, 1);
Comments:
If refoutput is true, then the output will be returned as a
reference to an array for efficiency.
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
force flag
Returns:
0 - ok
1 - could not start the service

none
