Step 3
Choose disruptive or nonDisruptive in the Restart drop-down list for any switch in the fabric that you
want to restart the fcdomain.
Step 4 Click the Apply Changes icon to initiate the fcdomain restart.
About 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 world-wide name (WWN) becomes the
principal switch.
The priority configuration is applied to runtime when the fcdomain is restarted (see the “About Domain
Restart” section on page 11-3). This configuration is applicable to both disruptive and nondisruptive
restarts.
Configuring Switch Priority
To configure the priority for the principal switch using Fabric Manager, perform this task:
Step 1 Expand Fabricxx > VSANxx, and then choose Domain Manager in the Logical Domains pane for the
fabric and VSAN that you want to set the principal switch priority for.
You see the domain’s running configuration in the Information pane as shown in Figure 11-4.
