Solution
Closed defect summary
Fixed in Fabric OS 6.4.1.
Workaround prior to upgrade:
User can verify that a fabric has this
problem by running
sloterrshow 1
on directors or
sloterrshow
on
switches; the
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.
When 8Gb switches and directors have an 8Gb blade in slot 1, frame drops
occur in the fabric when Ex/VEx ports are configured. Hosts cannot see
targets if there is an Ex/VEx port configured in the same ASIC chip as an
F/E port with EGID 0. Customer may observe poor performance in the fabric
when this condition occurs.
Fixed in Fabric OS 6.4.1.
After upgrading an HP StorageWorks 4/256 SAN Director with FC4-48
blades installed, the HP StorageWorks 4/256 SAN Director 4/48 blade
faults and traffic through the blade is disrupted. External RASLOG messages
EM-1051 are seen reporting that a slot inconsistency was detected.
Fixed in Fabric OS 6.4.1.
The Login database gets corrupted after several switch enable/disable
transitions. This happens when misbehaving devices bouncing offline/online
do not participate in LIP to acquire a valid AL_PA and then later try to login
with an invalid AL_PA.
