### Usage:  exmag_status_sync.sh.ecf $machine ########################
## Rsyncs the $MODEL status file to the backup machine after the 
## updates are made to ncorzdm.ncep.noaa.gov.
##
## 4/21/2014  Freeman  Replace random selection of remote host with
##                     production's round robin method of selecting a host
##                     If none of the hosts are pingable, print
##                     warning but do not fail.
## 8/18/2015 Deyong Xu Redmine#9090 change nmm to nmmb
## 11/02/2020 A Simon Change model name hires-fv3 to hrw-fv3
## 04/2023 A Simon    Change hwrf/hmon model names to hfsa/hfsb
