Database Merge Guidelines

A database merge refers to a union of the configuration database and static (unlearned) entries in the
active database. See the
When merging the database between two fabrics, follow these guidelines:
•
OL-16184-01, Cisco MDS SAN-OS Release 3.x
Distribution = OFF
configuration database = {A,B}
active database = {A,B, C
configuration database = {A,B,
E}
active database = {A,B, C*, D*}
Not applicable
configuration database = {A,B}
active database = {A,B, C*, D*}
active database = {A,B, C, D}
Not applicable

Verify that the activation status and the auto-learning status is the same in both fabrics.
