Issue

StorageGRID reports "Unable to connect to NODE_NAME on port 22: fingerprint SSH_KEY does not match for NODE_NAME IP ADDRESS" on storage node during hotfix installation.

SSH-ing from Primary Admin to the affected storage node reports:

Add correct host key in /root/.ssh/known_hosts to get rid of this message.

Offending ECDSA key in /root/.ssh/known_hosts:<number>. Remove with: ssh-keygen -f "root/.ssh/known_hosts" -R "<nodename>
