Endurance Manager 4-37
Identifying The Preferred CoServer For Surviving Failures
Under some failure scenarios, Endurance software must make a decision about which CoServer
to remove from the configuration to preserve application operations. A number of factors
regarding the health of the CoServers as well as mirror copy status and direction are considered
when the decision is made. However, in some circumstances, both CoServers may be
considered as equal candidates for removal. You can select a preferred CoServer to bias the
decision for CoServer removal such that the preferred CoServer will remain in operation if
possible.
If your operations requirements dictate that one site is the primary center, you may choose to
designate the CoServer at that site as the preferred CoServer. To do so, access the Components
Properties window on the Endurance Manager through View Properties.... Then browse the
components tree view, click on the Endurance Configuration entry and select the preferred
CoServer as shown below:
The selection of a preferred CoServer is valid for either SplitSite or non-SplitSite
configurations.
