Cause
The RSA Authentication Manager 8.x software knows the hardware (or virtual hardware) on which it is installed, so moving the virtual appliance from one ESX host to another (with regards to a VMware environment) will cause a problem with the Authentication Manager system fingerprint. The most common change is the MAC address of the virtual network card.
Resolution

An administrator is required to use the command rsautil manage-secrets –a recover to reset the system fingerprint.

   1. Using the steps in 000038244 - SSH to an RSA Authentication Manager server, use the rsaadmin account to logon to the operating system hosting the Authentication Manager instance.

login as: rsaadmin
Using keyboard-interactive authentication.
Password: <enter operating system user password>

RSA Authentication Manager Installation Directory: /opt/rsa/am
  1. Go to /opt/rsa/am/utils.
  2. Use the command ./rsautil manage-secrets –a recover to restore the system fingerprint.
rsaadmin@am85:> cd /opt/rsa/am/utils
rsaadmin@am85:/opt/rsa/am/utils> ./rsautil manage-secrets -a recover
Please enter OC Administrator username: <enter Operations Console administrator name>
Please enter OC Administrator password: <enter Operations Console administrator password>
Machine fingerprint restored successfully.
  1. Go to /opt/rsa/am/server and restart all RSA Authentication Manager services for the change to take effect How to stop, start, and restart RSA Authentication Manager 8.x services at the command line
