Hi all,
Looking to enable automatic failover in MCC-IP.
Doc states: metrocluster modify -allow-automatic-forced-switchover true
Output (same in advanced and diag):
Error: invalid argument "-allow-automatic-forced-switchover"
Does the command below do the same thing?
metrocluster modify -auto-switchover-failure-domain auso-on-cluster-disaster
[Job 442] Job succeeded: Modify is successful.
Thanks!

the option you're looking for is -allow-auto-forced-switchover, not -allow-automatic-forced-switchover.
And no, these two options do very different things, and you should really understand the implications of enabling a forced switchover (i.e. possible data loss)
usually you want automatic failover on DR-group disaster (i.e. if a whole HA pair is down, switchover is triggered, but only if NVRAM is in sync, or was in sync when the nodes went down). auso-on-cluster-disaster was the old setting where a failover in an 8-node mcc would not trigger even if a full HA pair was down. on 4-node MCCs those two failure domains are basically the same
if you saw the ...automatic-forced-switchover parameter in an official documentation, you should report it as a bug (or even file a PR to fix it)

Just found the command! Thanks.
