To set the switch priority: Step 1. Enter system view. 2. Enter VSAN view. 3. Configure a priority value for the switch. Command system-view vsan vsan-id priority value Remarks N/A N/A By default, the priority value of a switch is 128. Configuring the allowed domain ID list Configuring the allowed domain ID list has an effect on switches as follows: • Principal switch-Can only assign domains IDs within the allowed domain ID list. If the allowed domain ID list configured does not include any of the already assigned domain IDs or manually configured domain IDs, the configuration will fail. • Non-principal switch-The manually configured domain ID must be within the allowed domain ID list. Otherwise, the configuration will fail. The principal switch must assign the switch a domain ID within the allowed domain ID list. Otherwise, the switch refuses the assigned domain ID and isolates its interface connected to the principal switch. If the runtime domain ID for a switch is beyond the new allowed ID list, the configuration will also fail. HP recommends that you specify the same allowed domain ID list for the member switches of a VSAN. To configure the allowed domain IDs for a switch: Step 1. Enter system view. 2. Enter VSAN view. 3. Configure the allowed domain IDs for the switch. Command system-view vsan vsan-id allowed-domain-id domain-id-list Remarks N/A N/A By default, the allowed domain IDs are 1 to 239. Configuring a domain ID for a switch In different scenarios, the configured domain ID has different meanings. • In a statically built fabric, the configured domain ID is the actual domain ID of the switch. • In a dynamically built fabric, the configured domain ID is desired by the switch but might not be the actual domain ID. To statically build a fabric, you must manually configure a domain ID for each switch. To dynamically build a fabric, you can configure a desired domain ID for a switch, but the domain ID assigned to the switch might not be the desired one. The configured domain ID can be static type or preferred type. • In a statically built fabric, the two types make no difference. • In a dynamically built fabric, when a non-principal switch fails to obtain the desired domain ID from the principal switch, the non-principal switch can use another domain ID assigned by the principal 26

Configuring the allowed domain ID list
Configuring the allowed domain ID list has an effect on switches as follows:
•
Principal switch
—Can only assign domains IDs within the allowed domain ID list. If the allowed
domain ID list configured does not include any of the already assigned domain IDs or manually
configured domain IDs, the configuration will fail.
•
Non-principal switch
—The manually configured domain ID must be within the allowed domain ID
list. Otherwise, the configuration will fail. The principal switch must assign the switch a domain ID
within the allowed domain ID list. Otherwise, the switch refuses the assigned domain ID and
isolates its interface connected to the principal switch. If the runtime domain ID for a switch is
beyond the new allowed ID list, the configuration will also fail.
HP recommends that you specify the same allowed domain ID list for the member switches of a VSAN.

Configuring a domain ID for a switch
In different scenarios, the configured domain ID has different meanings.
•
In a statically built fabric, the configured domain ID is the actual domain ID of the switch.
•
In a dynamically built fabric, the configured domain ID is desired by the switch but might not be the
actual domain ID.
To statically build a fabric, you must manually configure a domain ID for each switch.
To dynamically build a fabric, you can configure a desired domain ID for a switch, but the domain ID
assigned to the switch might not be the desired one.
The configured domain ID can be
static
type or
preferred
type.
•
In a statically built fabric, the two types make no difference.
•
In a dynamically built fabric, when a non-principal switch fails to obtain the desired domain ID from
the principal switch, the non-principal switch can use another domain ID assigned by the principal
