ESA cluster issue - Node administratively disconnected

[jose.cortijo]

Hi,

I upgraded our two virtual ESA appliances following the official instructions up to version 14.0.1-033.

after the upgrade, the cluster was broken as expected and now I try to reconnect both machines and I am getting the following error

(Cluster XXXXX)> clustercheck

Warning: The following machines were not included in the check:
YYYYYY.zzzz (administratively disconnected)

No inconsistencies found on available machines.
(Cluster XXXX)> clusterconfig

Cluster XXXXX

If you are using SSH for cluster communication, verify if you are able to telnet the ESA IP on port 22 (viceversa). If it's working, disconnect the machine from cluster again and try running a quick hostscan for SSH keys.

Please enter the host or IP address to lookup.

Commit and then try to reconnect the ESA back into cluster.
