Cyber Recovery dashboard shows status as Degraded. All sync-copy jobs have failed. In the Cyber Recovery UI > Infrastructure > Assets > Vault Storage, attempting to edit the Data Domain asset and reenter the user password generates an alert when saving: The mgmtdds.log (located by default in /opt/dellemc/cr/var/log/mgmtdds/ ) contains the following information: [2023-08-03 03:30:57.658] [INFO] [mgmtdds] [ddssh.go:692 CreateSSHClientConn()] : Establish SSH connection using ssh-key with credential [2023-08-03 03:30:57.658] [INFO] [mgmtdds] [ddssh.go:719 CreateSSHClientConn()] : SSH connecting to dd.vault.local:22 [2023-08-03 03:30:57.731] [DEBUG] [mgmtdds] [sshkeys.go:320 getHostFingerprint()] : Entering [2023-08-03 03:30:58.145] [DEBUG] [mgmtdds] [sshkeys.go:397 getHostFingerprint()] : fingerprint: 40:CF:9D:61:97:35:F6:DF:43:8F:DE:27:2F:E5:48:B8:05:9E:B5:31 [2023-08-03 03:30:58.145] [DEBUG] [mgmtdds] [sshkeys.go:398 getHostFingerprint()] : Exiting [2023-08-03 03:30:58.145] [ERROR] [mgmtdds] [ddssh.go:757 CreateSSHClientConn()] : *** Alert *** Possible malicious behavior has been detected for host: dd.vault.local
When Cyber Recovery makes an SSH connection to Data Domain, it finds the fingerprint of the host has changed and issues a "malicious behavior" alert.
Perform the following steps to resolve the issue: Log in to Cyber Recovery UI as the crso user. Navigate to Infrastructure > Assets > Vault Storage. Select the vault Data Domain and click Edit. Enter the password for the user and then select the option for Reset Host Fingerprint. Click Save. Contact DELL Technical Support for any further information.
