When the supervisor DKC of the secondary storage system is TagmaStore USP/NSC and the subordinate DKCs are USP V, there are limitations for journal groups that can be registered in the extended consistency group. The journal groups that can be registered in an extended consistency group and the journal groups that cannot be registered in an extended consistency group are described below.
–As described in the configuration example 1 in Figure 3.40, the journal group of LDKC00 of USP V (subordinate DKC) can be registered in the extended consistency group.
–As described in the configuration example 2 in Figure 3.40, the journal group of LDKC01 of USP V (subordinate DKC) cannot be registered in the extended consistency group.
Note: Journal groups of LDKCs other than LDKC00 cannot be registered in the extended consistency groups when the supervisor DKC is TagmaStore USP/NSC, even if the number of LDKCs is expanded in a future version.
