emergency shutdown best practices.
Has anyone implemented or have suggestions on how to shutdown many remote unix/linux servers from a single script initiated from 1 server?
I need this to execute in parallel as time is not on my side. Our ups is sadly underrated and will die in approximately 15 minutes. (There is not any money in the budget to upgrade the ups.)

rrpc_shutdown
rrpc_shutdown(3ncs) rrpc_shutdown(3ncs)
Name
rrpc_shutdown - shut down a server
Syntax
#include <idl/c/rrpc.h>
void rrpc_$shutdown(handle, status)
handle_t handle;
status_$t *status;
Arguments
handle A remote procedure call (RPC) handle.
status The completion status. If the completion status returned in is equal to status_$ok , then the routine that supplied it was success-
ful.
Description
The routine shuts down a server, if the server allows it. A server can use the routine to allow or disallow remote shutdown.
Diagnostics
This section lists status codes for errors returned by this routine in
rrpc_$shutdown_not_allowd
You send an request to a server that has not issued an call.
Restrictions
On the client side, because of the way the calls are defined and implemented in the run-time library you must explicitly call into the
entry point vector table for the interface to send an request across the network. The following is an example of a call that works as
desired:
(*rrpc_$client_epv.rrpc_$shutdown)(handle, &status);
The server side stub routine calls the entry point on behalf of the client. The results of the call are then passed back to the client.
Before making the shutdown call, the server must have previously executed the following call:
rpc_$allow_remote_shutdown((unsigned long) TRUE,NULL,&status);
If the server has not allowed remote shutdown, the call returns an status code.
