Enabling Autoreconfiguration
To enable automatic reconfiguration in a specific VSAN (or range of VSANs) using Fabric Manager,
follow these steps:
Step 1 Expand Fabricxx > VSANxx and then select 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.
Step 2 Select the Configuration tab and check the Auto Reconfigure check box for each switch in the fabric
that you want to automatically reconfigure.
Step 3 Click the Apply Changes icon to save these changes.
Domain IDs
Domain IDs uniquely identify a switch in a VSAN. A switch may have different domain IDs in different
VSANs. The domain ID is part of the overall FC ID.
