exit code.

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*";

|
Will call get_ServiceNode to get the Service node ( name or ipaddress)
|
|
as known by the Management
|
|
Server or Node for the input nodename or ipadress of the node
|
|
It will then format the output into a single servicenode key with values
|
|
the list of nodes service by that service node. This routine will
|
|
break up pools of service nodes into individual node in the hash unlike
|
|
get_ServiceNode which leaves the pool as the key.
|
|
|
|
input: Same as get_ServiceNode to call get_ServiceNode
|
|
list of nodenames and/or node ipaddresses (array ref)
|
|
service name
|
|
"MN" or "Node" determines if you want the Service node as known
|
|
by the Management Node or by the node.
|
|
|
|
recognized service names: xcat,tftpserver,
|
|
nfsserver,conserver,monserver
|
|
|
|
service "xcat" is used by command like xdsh that need to know the
|
|
service node that will process the command but are not tied to a
|
|
specific service like tftp
|
|
|
|
|
|
output: A hash ref of arrays, the key is a single service node
|

pointing to
|

a list of nodes that are serviced by that service node

=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
