Cluster Server 8.0 Agent for EMC SRDF/Star Configuration Guide - Windows

In this scenario, the local site is not the current workload site. The online entry point attempts to make the local site the current workload site by doing the following:

• The entry point determines the state of STAR. If STAR is in a tripped state, the entry point checks the value of the TripTakeover attribute. If TripTakeover is set to 0, the SRDFStar resource does not go online. If the TripTakeover attribute is set to 1, the entry point makes the local site the current workload site. The entry point also makes the local site the current workload site if Star is in the halted or protected state.

• The entry point checks the value of the KeepDataFrom, KeepDataOn, and UseMostRecentData attributes as it makes the local site the current workload site. It checks these values to determine which site's data it uses to synchronize the local site.

  • If the UseMostRecentData attribute is set to 1, then the entry point determines which site has the most recent data using the symstar query command output and uses that output to synchronize the local site.

  • If the UseMostRecentData attribute is set to 0 and the KeepDataOn attribute is set to switch, then the KeepDataFrom attribute value is used to determine which site's data is to be used to synchronize the local site.
