I try to make all the two hosts go into maintenance mode in HA configuration.
when I started the maintenance mode of first ESXi, It works well after the host migrate guest os to another ESXi.
But when I started the maintenance mode of 2nd ESXi after the entering to maintenance mode of 1st ESXi host, It stop at 2%.
I think all all the guest OS shoud go into shutdown or power off because no other runnning ESXi exist.
But Guest OS do not go into shutdown, also 2nd ESXi host can not go into maintenan mode.
It seems that guest OS waiting to migrate to another host.
I don't know why Guest OS can not go into shutdown or power off even though no other running host exist.
