The host name of the local AE Server. |
Local AE Server IP Address |

The IP address of the AE Server. |
Remote AE Server IP Address | IP address of the remote AE Services server. |
Remote AE Server User Name |
User name of any user who is a part of the super user group and
has access to linux shell.

Remote AE Server User Password | The password of the remote user. |
Eth0 Virtual IP Address (optional) |

This field is optional. |
Eth1 Virtual IP Address (optional) |
The virtual IP address, which is used by the active AE Server.
This field is optional. |
Eth2 Virtual IP Address (optional) |
The virtual IP address, which is used by the active AE Server.
This field is optional. |
Failure Detection Interval | The Failure Detection Interval determines how long you want AE Services to wait before the standby AE Services server becomes active if the standby AE Services server cannot reach the current active AE Services server. The range is 1 - 3600 seconds. The default value is 600 seconds. |
Preferred Active Node (optional) |
The IP address of the preferred active node. The default value
is empty.
If Preferred Active Node is administered, during split brain resolution the preferred node will be chosen as the active AE Services server. If Preferred Active Node is not administered, the current active AE Services server remains active. Split brain is a condition when both AE Services servers are running in active mode due to network failure. When the network between the AE Services servers comes up, you must keep only one AE Services server active. This field is optional. |
System Type | The system type is based on the number of individual licenses allocated for this AE Services server. The system depends on the number of other AE Services licenses used on the AE Services server based on the following table. Choices are Small, Medium, and Large. |
HA Small License | HA Medium License | HA Large License | |
DLG (on/off) | NA | NA | HA Large required |
CVLAN (on/off) | NA | NA | HA Large required |

If an application exceeds the use of AE Services individual licenses for a configured Geo Redundant High Availability system size, AE Services Geo Redundant High Availability will enter the Geo Redundant High Availability license violation state. Once in the Geo Redundant High Availability license violation state, Geo Redundant High Availability will prohibit failover for any reason until the license violation state is cleared. There are two ways to clear the license violation state:
|
Reducing the usage of AE Services individual licenses after the license violation state is reached will not clear the license violation state.
