Chapter 26 Configuring Domain Parameters
Specifying a Preferred or Static Domain ID
Viewing Domain Areas
To monitor domain areas from the Device Manager, choose Domain Manager from the FC menu and
click the Areas tab. The Domain Manager dialog box, with the Areas tab selected, displays domain areas
for a single switch.
Viewing Domain Area Ports
To monitor area ports for domains from the Device Manager, choose Domain Manager from the FC
menu and click the Area Ports tab. The Domain Manager dialog box, with the Area Ports tab, displays
area ports for domains for a single switch.
Specifying a Preferred or Static Domain ID
If you change the configured domain ID, the change is only accepted if the new domain ID is included
in all the allowed domain ID lists currently configured in the VSAN. Alternatively, you can also
configure zero-preferred domain ID.
Note
The 0 (zero) value can be configured only if you use the preferred option.
While the static option can be applied to runtime after a disruptive or nondisruptive restart, the
preferred option is applied to runtime only after a disruptive restart.
Tip When the FICON feature is enabled in a given VSAN, the domain ID for that VSAN will remain in the
static state. You can change the static ID value but you cannot change it to the preferred option.
Setting Switch Priority
By default, the configured priority is 128. The valid range to set the priority is between 1 and 254.
Priority 1 has the highest priority. Value 255 is accepted from other switches, but cannot be locally
configured.
Any new switch cannot become the principal switch when it joins a stable fabric. During the principal
switch selection phase, the switch with the highest priority becomes the principal switch. If two switches
have the same configured priority, the switch with the lower WWN becomes the principal switch.
Configuring Allowed Domain ID Lists
By default, the valid range for an assigned domain ID list is from 1 to 239. You can specify a list of
ranges to be in the allowed domain ID list and separate each range with a comma. The principal switch
ensures that the domain requested by any switch in the fabric is specified in the allowed list.
