MAP 0700: Fabric, ISL, and Segmented Port Problem Determination
3-117
Maintenance Analysis Procedures (MAPS)
assigned a priority of 1 and controls the allocation and
distribution of domain IDs for all fabric directors and 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 dialog box.
e. Set the director online (Set the Director Online or Offline on
page 4-43).
Did the switch priority change solve the problem and did both
directors join through the ISL to form a fabric?
NO YES
↓ The directors, associated ISL, and multiswitch fabric appear
operational. Exit MAP.
Contact the next level of support. Exit MAP.

A director E_Port segmented (at an operational director) because a
response to a verification check indicates an attached director or
switch is not operational.
a. Perform the data collection procedure at the operational director
and return the CD to McDATA for analysis. This information may
assist in fault isolating the failed director.
b. Go to MAP 0000: Start MAP on page 3-9 and perform fault
isolation for the failed director.
Exit MAP.

A 140 event code occurs only if the optional OpenTrunking feature is
enabled. The event code indicates OpenTrunking firmware detected
an ISL with Fibre Channel traffic that exceeds the configured
congestion threshold.
