You can reset the Secure Shell (SSH) fingerprint for a cluster that is managed by the SAN Volume Controller Console for your configuration on the Resetting the SSH Fingerprint panel.
You must have administrator authority to reset the SSH fingerprint. The SAN Volume Controller Console displays the status of the cluster SSH server key in the Availability Status column of the Viewing Clusters panel. To reset the SSH fingerprint, select a cluster that has an Availability Status of Invalid SSH Fingerprint. In some cases this availability status results from a software upgrade that disrupts normal user operations.
The SAN Volume Controller Console and the cluster communicate through the SSH protocol. In this protocol, the SAN Volume Controller Console acts as the SSH client and the cluster acts as the SSH host server. The SSH protocol requires that credentials are exchanged when communication between the SSH client and server begins. The SSH client places the accepted SSH host-server fingerprint in cache. Any change to the SSH server fingerprint in future exchanges results in a challenge to the user to accept the new fingerprint. When a new code load is completed on the cluster, new SSH server keys can be produced that result in the SSH client flagging the SSH host fingerprint as changed and, therefore, no longer valid.
