Hi experts,
I created an AlwaysOn Availability before but due to a 10GbE NIC driver issue(it rans 10X slower than before) I manually removed AG to keep the SAP system/SQL DB running.
I want to rebuild now and I find it always failed at "ALTER AVAILABILITY GROUP [AGTP1] JOIN;"
I have checked every steps mentioned in link below: both firewalls are disabled, both endpoint are created and enabled with the role:sysadmin, service accounts are domain admins, telnet port 5023 are ok.
I still can't get a clue, please help. Thanks.
