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 [1]”. 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

Where Else Fixed: FOS6.3.2

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.

Feature: 4G ASIC Driver Function: ASIC Driver

Probability: Low

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.
