to cancel the HA
Can I create new one directly or I need do something in advance?
You can, sure, but would you like help in fixing your existing vCenter, or are you fine just taking a sledge hammer to it at this point?
I am a noob in VM, and now I'm suffering a problem in 503 Service Unavailable (Failed to connect to endpoint:
I have googled for replace vCenter, they said i need to delete the ESXi server from HA. So i' m confusing that if I can't delete ESX from HA, could I make a new VCSA to replace the old one.
I got same issue and I just tried below steps to fix the issue
1. Reset same vcha password on three node - Active, Passive & Witness on vCenter through VM's console (KB # 2148675 - VMware Knowledge Base )
# passwd vcha
2. Run the following cmd to destroy vCHA on "Active Node"
# destroy-vcha ( Resolving Failover Failures )
3. Reset "Passive Node" through below cmd and make it primary >>> Powered off other two "Active & Witness" Node >> Rebooted Passive Node and vCenter came back online.
# vcha-reset-primary ( Resolving Failover Failures )
I'm so sorry that i have even not find the file /var/log/vmware/vcha/vcha.log. Also, I can'find the command too.
Did you check all three node in vcenters under vCHA ?
try below cmd on all node of vcenters and let me know, what you will get.
# passwd vcha
