Solution
Closed defect summary
Fixed in Fabric OS 6.4.0
In FICON environment, Fabric OS is not generating RLIRs for link incid-
ents on cascaded Fabric OS switches in IM0.
Fixed in Fabric OS 6.4.0
Internal buffer corruption in zoned during zone merge process causes
zone merge failure and switch panic.
Fixed in Fabric OS 6.4.0
No cascaded FICON CUP connectivity on 4/256 director with 8Gb
blade when E_Port and F_Port are on different ASICs on the blade.
Fixed in Fabric OS 6.4.0
Switch panic occurs when management application performs repeat
FCP LUN emulation queries. If the device gives an inappropriate re-
sponse, or no response, to an FCP LUN request, FCP Daemon retries
the query and the thread becomes stuck. Any new FCP LUN request
that is issued from the management application generates a new thread.
Eventually, FCP Daemon generates up to the maximum number of al-
lowed threads, leading to the switch panic.
Fixed in Fabric OS 6.4.0
Licenses removed during firmware downgrade from Fabric OS 6.3.0b
to 6.2.0e.
Fixed in Fabric OS 6.4.0
Workaround prior to upgrade:
In the threshold alarm matrix
configuration for all port related
thresholds, disable
ErrLog
and Port
Fencing (using
fwconfigure
) this
will avoid the above functions from
being called (on any threshold
events) and leaking or enable
fwalarmsfilterset
.
If Fabric Watch
fwalarms
is turned off and
Errlog
is turned on,
fabric watch daemon can crash causing a switch panic.
Fixed in Fabric OS 6.4.0
Workaround prior to upgrade:
Always add FC ports before adding
GE ports to an LS. When removing
ports from an LS, remove GE ports
before FC ports.

tion fails to come up online as EX_Port.

Workaround prior to upgrade:
Issue

to sync up the VT/VI database
across nodes in the EG.
Host failed to discover tapes due to a VI/VT (Virtual Initiator/Virtual
Target) database mismatch between the switches that are part of the
same Encryption Group. Therefore, the host cannot discover tape devices
that are part of the same EG.
