a. Inform the customer the product will be set offline. Ensure the
system administrator quiesces Fibre Channel frame traffic and
sets attached devices offline.
b. Set the product offline. Refer to Set online state (EFCM Basic
Edition) or Set online state (Element Manager).
c. For the product reporting the problem:
— EFCM Basic Edition - Select Switch and Fabric Parameters
from the Configure menu at any view. The Fabric
Parameters View displays.
— Element Manager - Select Operating Parameters and
Fabric Parameters from the Configure menu at any view.
The Configure Fabric Parameters dialog box displays.
d. At the Switch Priority field, select Principal , Never Principal , or
Default , then click OK or Activate . The switch priority value
designates the fabric’s principal switch, which is assigned a
priority of
1 and controls the allocation and distribution of domain
IDs for all fabric elements (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 the fabric element is incapable of
becoming a principal switch. If all elements are set to Principal or
Default , the element with the highest priority and the lowest
WWN becomes the principal switch. At least one element in a
multiswitch fabric must be set as
Principal or Default . If all
elements are set to Never Principal , all ISLs segment.
e. Set the product online. Refer to Set online state (EFCM Basic
Edition) or Set online state (Element Manager).
