• The PG DMP system ID must be the same on both PGs of a duplex pair for the pair to form duplex. in context
• PG port ranges follow installation order on the host rather than the PG number: if PG2 is installed before PG1 on a server, PG2's processes take the 43xxx range and PG1 is given the 45xxx range. in context
• The ICM instance number, stored in the registry under the customer instance's CurrentVersion key, must match on both PGs of a pair; a mismatch prevents the pair from forming duplex. in context
• Cisco identifies mismatched PG port assignments between the two servers of a duplex PG pair as a typical cause of a PG remaining in the isolated-enabled state, especially after a fresh install or upgrade. in context
• UCCE PG port numbers shift by 40 per ICM instance: the port for instance n equals the instance-0 port plus 40 times n. in context
• Cisco attributes PG port mismatches between pairing servers to existing ICM installations, or remnants of them, on the servers. in context
• For a duplex PG that will not leave isolated-enabled after install or upgrade, checking that instance number, DMP system ID and MDS/OPC ports match on both sides is a cheaper first step than log analysis. inferred in context
