Added document version and date (to be updated manually).
Updated checkpoints.rep in journalPrefix path to journals.rep.
Added sections to correct page numbers, so we don't have (e.g.)
page 6 of 5.
Tweaked doc titles to "Disaster Recovery Failover Plan/Unix/Replica Server"
and "Disaster Recovery Failover Plan/Unix/Standby Replica Server,"
to more closely match file name and content.
Tweaked to consistently use the word 'failover', replacing
variants like "fail-over" and "fail over."
