• CSCtz85952
Symptom: An F port interface goes down and will not come back up. The following error message
is displayed:
Link failure Link Reset failed nonempty recv queue
This issue only affects interfaces on the Cisco MDS 9000 48-port 8-Gbps Advanced Fibre Channel
Switching Module (DS-X9248-256K9) or the Cisco MDS 9000 32-port 8-Gbps Advanced Fibre
Channel Switching Module (DS-X9232-256K9). It is triggered by shutting the last member (or the
interface itself) of a downstream next-hop PortChannel while high rates of traffic are flowing from
the edge port into the PortChannel.
This issue cannot be cleared by shutting and not shutting the affected interface. It can be identified
for an affected interface fc x/y with the following command:
switch# attach module {x}
module-x# show hardware internal credit-info port {y}
Buffers are all used. (Configued-0x20, used = 0x26)
module-x# exit
The number of buffers used is greater than those configured.
Workaround: This issue is resolved.
• CSCtz99466
Symptom: The FSCM process exits without deregistering from Cisco Fabric Services (CFS). As a
result, the following CFS events occur:
Wed May 2 15:44:41 2012 :
MTS send failed, retval -1, errno 32 [Broken pipe]
Dest sap 139, opcode 8465
This symptom occurs after the FSCM process exits or fails or both four times and is not restarted
due to a sysmgr policy.
Workaround: This issue is resolved.
• CSCua02159
Symptom: Hosts that are zoned by a device alias cannot see storage.
This symptom occurs in an active zone set, and there is no FCID next to the device alias; however,
the FCID is in the FCNS database.
switch# show zoneset active
zone name myserver_hba0-mystorage_8D0 vsan 10
* fcid 0x363d00 [device-alias myserver_hba0]
device-alias mystorage_8D0
switch# show fcns database
