Preemption Mode

Preemption provides a means for users with sufficient privilege to take control
of a server from another user with lesser or equal privilege.
NOTE:
All users sharing the connection that is being preempted will be warned,
but only the primary user will be able to reject the preemption (if allowed).
Table 4-4 outlines the preemption scenarios and detailed scenarios in which
preemption requests can be rejected. For information about preemption and
reserved or locked virtual media sessions, see "Virtual Media" on page 78.
