> # Domain Manager Configuration

> Field | Description
> --- | ---
> Enable | Enables the Domain Manager on this VSAN. If enabled on an active VSAN, the switch will participate in principal switch selection. If disabled, the switch will participate in neither the principal switch selection nor domain allocation. Thus, Domain ID needs to be configured statically.
> Running DomainId | The configured Domain ID of the local switch on this VSAN or 0 if no Domain ID has been configured. The meaning depends on DomainIdType. If Type is 'preferred', then domain ID configured is called 'preferred Domain ID'. The valid values are between 0 and 239. In a situation where this domain could not be assigned, any domain ID would be acceptable. The value '0' means any domain ID. If Type is 'static' (insistent), then domain ID is called 'static Domain ID' and valid values are between 1 and 239. In a situation where this domain was non-zero but could not be assigned, no other domain ID would be acceptable. If the Domain Manager is enabled on the VSAN, then a RDI (Request Domain ID) will be sent requesting this Domain ID. If no Domain ID can be granted in the case of 'preferred' or if the configured 'static' (insistent) domain ID cannot be not granted then, it is an error condition. When this error occurs, the E_ports on that VSAN will be isolated. If the domain manager is not enabled, then the static (insistent) Domain ID is assumed to be granted, if it has been configured (to a valid number). If either of the domain IDs are not configured with a non-zero value on this VSAN and if the domain manager is not enabled, then - switch will isolate all of its E_ports on this VSAN.
> DomainId Type | Type of configured Domain ID.
> FabricName | The WWN that is used for fabric logins on this VSAN. This is used only if Enable is false. If Enable is true, then principal switch WWN is used. It is automatically set to the default value when set to zero-length value.
> Priority | Priority of the switch to be used in principal switch selection process.
> Contiguous Allocation | Determines how the switch behaves when elected as the principal switch. If true, switch won't accept non-contiguous domain IDs in RDIs and will try to replace all the Domain IDs in the list with contiguous domain IDs if a RDI for a contiguous Domain ID can not be fulfilled. If false, then the switch acts normally in granting the Domain IDs even if they are not contiguous.
> Auto Reconfigure | Determines how the switch responds to certain error conditions. The condition that can cause these errors is merging of two disjoint fabrics that have overlapping Domain ID list. If true, the switch will send a RCF (ReConfigureFabric) to rebuild the Fabric. If false, the switch will isolate the E_ports on which the errors happened.
> Persistent FcId | If true, then all the FC ID assigned on this VSAN are made persistent on this VSAN. If false, then all the entries on VSAN in PersistencyTable are deleted.
> Purge FcIds? | Tells the Domain Manager to purge the FC IDs on this VSAN in the FC ID persistency database.
> Restart? | Tells the Domain Manager to rebuild the Domain ID tree all over again. If 'disruptive', then a RCF (ReConfigure Fabric) is generated in the VSAN in order for the fabric to recover from the errors. If nonDisruptive, then a BF (Build Fabric) is generated in the VSAN.
> Optimization | You need to click the field to select one of the following. To disable turbo mode, do not select anything. Fast-Restart- Set the optimization type to fast restart. Selective-Restart- Set the optimization type to selective restart.
