• Intrepid 6064 Director in a multiswitch fabric that has more than
48 ISLs attached.
• Intrepid 6140 Director in a multiswitch fabric that has more than
70 ISLs attached.
• Other fabric element (director or switch) in a multiswitch fabric
that has more than 32 ISLs attached.
Fibre Channel frames may be lost or routed in loops because of
potential fabric routing problems. Advise the customer of the problem
and work with the system administrator to reconfigure the fabric so
that no director or switch elements have more than the proscribed
number of ISLs.
Did fabric reconfiguration solve the problem?
NO YES

A 070 event code indicates the E_Port detected an incompatibility
with an attached switch and prevented the switches from forming a
multiswitch fabric. A segmented E_port cannot transmit Class 2 or
Class 3 Fibre Channel traffic.
A 071 event code indicates the switch is isolated from all switches in a
multiswitch fabric, and is accompanied by a 070 event code for the
segmented E_Port. The 071 event code is resolved when all 070
events are corrected.
Obtain supplementary event data for the 070 event code.
a. At the Event Log or the SANpilot event log, record the first four
bytes (0 through 3) of event data.
b. Examine the first five bytes (0 through 4) of event data.
c. Byte 0 specifies the port number (00 through 31) of the
segmented E_port. Byte 4 specifies the segmentation reason as
listed in the following table.
