When the FICON feature is enabled in a given VSAN, the domain ID for that VSAN remains in the static

state. You can change the static ID value but you cannot change it to the preferred option.

In an IVR without NAT configuration, if one VSAN in the IVR topology is configured with static domain

IDs, then the other VSANs (edge or transit) in the topology should also be configured with static domain

In an IVR NAT configuration, if one VSAN in the IVR topology is configured with static domain IDs,

then the IVR domains that can be exported to that VSAN must also be assigned static domains.

You must restart the fcdomainif you want to apply the configured domain changes to the runtime

If you have configured an allow domain ID list, the domain IDs that you add must be in that range for

the VSAN. See the

Specifying Static or Preferred Domain IDs

When you assign a static domain ID type, you are requesting a particular domain ID. If the switch does

not get the requested address, it will isolate itself from the fabric. When you specify a preferred domain

ID, you are also requesting a particular domain ID; however, if the requested domain ID is unavailable,

then the switch will accept another domain ID.

While the static option can be applied at runtime after a disruptive or non-disruptive restart, the preferred

option is applied at runtime only after a disruptive restart (see the

Within a VSAN all switches should have the same domain ID type (either static or preferred). If a

configuration is mixed–some switches with static domain types and others with preferred–then you may

experience link isolation.

To specify a static or preferred domain ID using Fabric Manager, follow these steps:

Expand Fabricxx > VSANxx and then select Domain Manager in the Logical Domains pane for the

fabric and VSAN that you want to configure the domain ID for.

You see the running configuration of the domain in the Information pane.

Enter a value for the Config DomainID and click static or preferred from the Config Type drop-down

menu to set the domain ID for switches in the fabric.

Click the Apply Changes icon to save these changes.
