Troubleshooting Fibre Channel switch backup configuration issues

Use the following guidelines and suggested steps to help resolve Fibre Channel switch backup configuration issues.

  • Condition:

    When backing up a Fibre Channel switch configuration, the following error occurs:

    Host key verification failed

  • Probable Cause:

    A host key or the host already exists; it must be deleted.

  • Corrective Action:

    Log on to the Fibre Channel switch CLI and delete all known host keys for the host using the following command:

    sshutil delknownhost

    For example:

    R1-G620-B:admin> sshutil delknownhost
    IP Address/Hostname to be deleted:<IP address or hostname>
    Known Host deleted successfully.
