Test Hyper-V Replica fail over
scenario: Two standalone windows hyper-v replica connection was established and replication was enable between primary host (testhost.tplhk.local) and replica server (testreplica.tplhk.local).
Planned Fail over (Scenario: for example primary host need to shutdown for MA, all VMs in primary host switch to replica server and continue running on replica server until primary host resumed)
steps
stop VM in primary host (testhost.tplhk.local)
right click VM and select Planned Failover with Reserve and start VM in replica server selection (Now VM in testreplica.tplhk.local server with start automatically and replica role will swap each other testhost changed to replica server and testreplica changed to primary server)
When original host resumed(testhost.tplhk.local)
stop VM in replica host (testreplica.tplhk.local)
right click VM and select Planned Failover with Reserve and start VM in replica server selection (Now VM in testhost.tplhk.local server with start automatically and replica role will swap back). ** all change during in testreplica will still here , no data lost ****
UnPlanned Fail over (Scenario: for example primary host unplanned shutdown or damaged that unable to resume in short time. then run VM in replica server.)
steps
right click VM and select failover (on testreplica.tplhk.local , VM will start and running)
once primary host resumed, may be over a month and replica setting were applied.
shutdown VM (on testreplica.tplhk.local)
right click VM and select Planned Failover with Reserve and start VM in replica server selection (on testreplica.tplhk.local) - a inital copy will transfer from testreplica.tplhk.local to testhost.tplhk.local) and VM will start in testhost.tplhk.local.)
*** dont use planned failover without reserve option , replica will have problem when replia , VM will paused wait you to fixed it****
