About Autoreconfiguring Merged Fabrics
By default, the autoreconfigure option is disabled. When you join two switches belonging to two
different stable fabrics that have overlapping domains, the following situations can occur:
• If the autoreconfigure option is enabled on both switches, a disruptive reconfiguration phase is
started.
• If the autoreconfigure option is disabled on either or both switches, the links between the two
switches become isolated.
The autoreconfigure option takes immediate effect at runtime. You do not need to restart the fcdomain.
If a domain is currently isolated due to domain overlap, and you later enable the autoreconfigure option
on both switches, the fabric continues to be isolated. If you enabled the autoreconfigure option on both
switches before connecting the fabric, a disruptive reconfiguration (RCF) will occur. A disruptive
reconfiguration may affect data traffic. You can nondisruptively reconfigure the fcdomain by changing
the configured domains on the overlapping links and eliminating the domain overlap.
Enabling Autoreconfiguration
To enable automatic reconfiguration in a specific VSAN (or range of VSANs) using Fabric Manager,
perform this task:
Step 1 Expand Fabricxx > VSANxx, and then choose Domain Manager in the Logical Domains pane for the
fabric and VSAN that you want to enable automatic reconfiguration for.
You see the running configuration of the domain in the Information pane.
