Geographic Redundancy-unaware (GR-unaware) elements are elements that cannot support the System Manager Geographic Redundancy feature. GR-unaware elements might be legacy elements, that is, prior to Release 6.3, which are already present in the field or elements that have not yet leveraged the System Manager Geographic Redundancy feature.
This document provides the procedures required when a primary System Manager is unavailable to reconfigure the GR-unaware elements in the system. After the reconfiguration is complete, the elements can communicate with the secondary System Manager server to receive management or configuration information. This document also describes the functioning of GR-unaware elements with System Manager in general and the secondary System Manager server in particular.
Note:
The system does not replicate the /etc/hosts file of the primary System Manager server to the secondary System Manager server. If you have elements that depend on the entries present in the /etc/hosts file of the primary server, you must make the appropriate entries during the failover process.
