b. Set the switch offline. Refer to Set the Switch Online or Offline
on page 4-25.
c. At the View panel, select Configure at the left side of the panel.
The Configure panel opens with the Ports page displayed.
d. Click the Switch tab, then click the Fabric Parameters tab. The
Fabric Parameters page displays. The switch priority value
designates the fabric’s principal switch. The principal switch is
assigned a priority of 1 and controls the allocation and
distribution of domain IDs for all fabric switches (including itself).
Principal is the highest priority setting, Default is the next
highest, and Never Principal is the lowest priority setting. The
setting Never Principal means that the switch is incapable of
becoming a principal switch. If all switches are set to Principal or
Default, the switch with the highest priority and the lowest WWN
becomes the principal switch.
At least one switch in a multiswitch fabric must be set as
Principal or Default. If all switches are set to Never Principal, all
ISLs segment and the message No Principal Switch appears in
the Reason field of the Port Properties page.
e. At the Switch Priority field, select Principal, Never Principal, or
Default (the default setting is Default), then click Activate to save
the change. The message Your changes to the fabric
parameters configuration have been successfully activated
appears.
f. Set the switch online. Refer to Set the Switch Online or Offline
on page 4-25.
Did the switch priority change solve the problem and did both
switches join through the ISL to form a fabric?
NO YES
