E_Port Segmentation Reasons And Actions - IBM TotalStorage SAN140M Installation And Service Manual

6
Fabric Controller software detected:
• 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.

An 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
displays at the Port List View (EFCM Basic Edition) or Port
Properties dialog box (Element Manager).
