ER & HDR and CDR_SERIAL reset.

11.50 FC8 AIX 6.1 A & B servers are exisiting update anywhere servers between themselves. CDR_SERIAL on A is 2,2, CDR_SERIAL on B is 2,1 C was recently added as a HDR updatable secondary to A. ( C will eventually become the new A once all applications are migrated over.) The HDR setup went fine using restore from A to C (ontape -p) and everything replicated over fine and continues to do so. However on weekly restart A now complains that CDR SERIAL is out of range and resets CDR_SERIAL from 2,2 to 2,0. CDR_SERIAL on B still remains set to 2,1 on it's restart. Is this reset due to the syscdr database being included in the restore from A to C and A is sensing that C is in the ER mix also even though only two CDR servers are defined in the environment ? Thanks, Mark
