MAP 0600: Fabric or ISL Problem Analysis
3-41
Maintenence Analysis Procedures
• A fabric element with more than 32 ISLs (SAN management
application Version 3.2 or earlier).
• A fabric element with more than 128 ISLs (SAN management
application Version 3.3 or later).
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
↓ The fabric, ISL, and product are operational. Exit MAP.
Contact the next level of support. Exit MAP.

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 Tabl e 3- 14 . The reason also
displays at the Port List View (EFCM Basic Edition) or Port
Properties dialog box (Element Manager).
Table 3-14 E_Port Segmentation Reasons and Actions
Byte 4 Segmentation Reason Action
01 Incompatible operating parameters. Go to step 8.
02 Duplicate domain ID. Go to step 9.
03 Incompatible zoning configurations. Go to step 10.
04 Build fabric protocol error. Go to step 11.
05 No principal switch. Go to step 13.
06 No response from attached switch (hello timeout). Go to step 14.
