Chapter 26 Configuring Domain Parameters

Restarting the Domain

Fibre Channel domains can be started disruptively or nondisruptively. If you perform a disruptive restart,
reconfigure fabric (RCF) frames are sent to other switches in the fabric. If you perform a nondisruptive
restart, build fabric (BF) frames are sent to other switches in the fabric.
A static domain is specifically configured by the user and may be different from the runtime domain. If
Note
the domain IDs are different, the runtime domain ID will change to take on the static domain ID after
the next restart.
If a VSAN is in interop mode, you cannot restart the fcdomain for that VSAN disruptively.
Tip

Performing a Domain Restart

To restart the fabric disruptively or nondisruptively, follow these steps:
Step 1 Open Device Manager on a switch in the domain you want to restart.
Step 2 Choose FC > Domain Manager. You see the Domain Manager dialog box.
Click in the Restart column for the VSAN ID for which you want to restart the domain. You see a
Step 3
drop-down list of options.
Choose disruptive for a disruptive restart, or Non-disruptive for a non-disruptive restart.
Step 4
Click Apply to restart the domain.
Step 5

Configuring the Domain

The configured domain ID can be preferred or static. By default, the configured domain is 0 and the
configured type is preferred. If you do not configure a domain ID, the local switch sends a random ID
in its request.
When a subordinate switch requests a domain, the following process takes place.

The local switch sends a configured domain ID request to the principal switch.
The principal switch assigns the requested domain ID if available, otherwise, it assigns another
available domain ID.
