2 figures:

1) you have HP MC/ServiceGuard and so we are talking of a HA cluster, in which case if correctly configured it can to be up again in minutes or even less...

2) You are not in a HA cluster but you are on a SAN with 2 or more HBAs, in which case
you have to write the scripts to vgchange the volume groups of the defunct server you see the PV thanks to the SAN admins...after sanity check and mount adequately you ca start the new instance but you are stuck with 2 things:
a) the host's name
b) its IP address

It can work (I did it long ago with 2 D class...) lets say you have a developpement server and a production server almost identical, if the production server drops, you can sacrify your test server by having the adequate config scripts ready ( with passwd etc...) and after reboot it replaces the faulty prod, having same name and IP...

NAME
qrun - run a pbs batch job SYNOPSIS
qrun [-a] [-H host] job_identifier ... DESCRIPTION
The qrun command is used to force a batch server to initiate the execution of a batch job. The job is run regardless of scheduling posi- tion, resource requirements, or state. In order to execute qrun, the user must have PBS Operation or Manager privilege. OPTIONS
-a Specifies the job(s) is to be run asynchronously. -H host Specifies the host within the cluster on which the job(s) are to be run. The host argument is the name of a host that is a member of the cluster of hosts managed by the server. If the option is not specified, the server will select the "worst possible" host on which to execute the job. OPERANDS
The qrun command accepts one or more job_identifier operands of the form: sequence_number[.server_name][@server] STANDARD ERROR
The qrun command will write a diagnostic message to standard error for each error occurrence. EXIT STATUS
Upon successful processing of all the operands presented to the qrun command, the exit status will be a value of zero. If the qrun command fails to process any operand, the command exits with a value greater than zero. SEE ALSO
