Matching fabric-wide consistency policies

This section describes the interaction between the databases with active SCC and DCC policies
and combinations of fabric-wide consistency policy settings when fabrics are merged.

For example: Fabric A with SCC:S;DCC (strict SCC and tolerant DCC) joins Fabric B with SCC:S;DCC
(strict SCC and tolerant DCC), the fabrics can merge as long as the SCC policies match, including
the order SCC:S;DCC and if both are set to strict.

Table 38

describes the impact of merging fabrics with the same fabric-wide consistency policy that

have SCC, DCC, or both policies.

Non-matching fabric-wide consistency policies

You may encounter one of the following two scenarios described in

Table 39

and

Table 40

where

you are merging a fabric with a strict policy to a fabric with an absent, tolerant, or non-matching
strict policy and the merge fails and the ports are disabled.

Table 39

on page 164 shows merges that are not supported.
