137 Chapter 3: Maintenance analysis procedures
Fibre Channel frames may be lost or directed in loops because of
potential fabric routing problems. Advise the customer of the problem
and reconfigure the fabric so that no directors or switches have more
than the proscribed number of ISLs.
Was the maintenance action successful?
NO YES

Event code 070 indicates an E_Port detected an incompatibility with
an attached fabric element, segmented the port, and prevented fabric
participation. A segmented E_port cannot transmit Class 2 or Class 3
Fibre Channel traffic. Event code
071 indicates the product is isolated
from all fabric elements, and is accompanied by an event code 070
for each segmented E_Port. Event code 071 is resolved when all 070
events are corrected. Obtain supplementary event data as follows:
a. At the Event Log , examine the first five bytes of event data.
b. Byte 0 specifies the segmented E_port. Byte 4 specifies the
segmentation reason as listed in Table 18 . The reason also
displays at the Port List View (EFCM Basic Edition) or Port
Properties dialog box (Element Manager).
