Fabric OS v6.4.1 Release Notes v1.0 Page 35 of 62
Defect ID: DEFECT000269222 Technical Severity: High
Summary: 8G switches, and directors with an 8G blade in slot 1, see frame drops in the fabric when
there are Ex/VEx ports configured
Symptom: If there is an Ex/VEx port configured in the same ASIC chip as a F/E port with EGID 0, hosts
cannot see the targets and customer may observe poor performance in the fabric .
Workaround: User can identify a fabric has this problem by running "sloterrshow 1"on directors or
sloterrshow on switch, and "type6_miss” counter should be seen continuously
incrementing during traffic load on backend port/E_Port. Avoid configuring an EX_Port or
a VEx_Port near an F/E port with an EGID of 0. To identify a port with an EGID of 0, login
in as root and run “bladeportmap ”. The first port where “Upt” is not -1 uses EGID 0.
Once the problem occurs, the user must make the F/E port into an EX_Port and then
configure it back to an F/E port to fix the problem port. Execute the following instructions.
1) Disable the F/E port
2) Configure the F/E port as an EX_Port for a valid FID
3) Connect a link between the FID and the EX port (IFL)
4) Enable the port
5) Verify that the link is online. Then disable the port
6) Disable the EX_Port configuration
7) Connect the host/ISL back to the F/E port
8) Enable the port

Defect ID: DEFECT000278024 Technical Severity: High
Summary: If a PLOGI is received right before hafailover / hot code load on a Brocade 48000 with FC4-
48 blades installed, and the PLOGI has zone misses for devices communicating through
the primary shared area port, it faults the CP and generates EM-1051 messages.
Symptom: After upgrading a Brocade 48000 with FC4-48 blades installed, the FC4-48 blade faults
and traffic through the blade is disrupted. External RASLOG messages EM-1051 are seen
reporting a slot inconsistency detected.

Defect ID: DEFECT000282352 Technical Severity: High
Summary: Login database gets corrupted after several switch enable/disable transitions. This
happens when misbehaving devices bouncing offline/online don't participate in LIP to
acquire a valid AL_PA and then later try to login with an invalid AL_PA
Symptom: Kernel panic occurs after several switch disable/enable transitions.
