Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(8a) (OL-27554-05, May 16, 2013)

Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(8a)

OL-27554-05

Caveats

Condition: If the user modifies an active FCIP tunnel compression parameter from the Device

Manager, unwanted logs get redirected to the startupdebug file of the MSM-18/4 module. Because

of the high utilization of the FCIP tunnel, this operation creates a large (4 MB) file that causes

memory exhaustion.

Workaround: This issue is resolved.

• CSCue92054

Symptom: The inter-VSAN routing (IVR) feature checks out the SAN_EXTN_OVER_IP_18_4

license that results in the FCIP shut down.

Condition: IVR checks out the count of the license from 18_4 and SSN_16. Fibre Channel over IP

(FCIP) fails with this error:

"No fcip license or a license failure (0x403c0033

Workaround: This issue is resolved.

• CSCud49969

Symptom: The following error appears when the isapi health-check command is used after

attaching the Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4):

Memory Status: ERROR

Condition: After attaching the MSM-18/4 module and entering the isapi health-check command.

Workaround: This issue is resolved.

• CSCud72991

Symptom: A port drops all packets originating from the supervisor module although the port is up

and allotted with sufficient transmit (Tx) buffer-to-buffer credits.

Condition: The input and output rate is 0 frames per second.

Workaround: This issue is resolved.

• CSCuf31077

Symptom: Ports on the 24-port, 48-port, or 4/44-port 8-Gbps Fibre Channel switching modules go

into a suspended state and packets cannot egress or ingress on the port. This issue occurs on Cisco

MDS 9500 Series Directors and Cisco MDS 92221 switches when any of the following modules are

installed:

–

24-port 8-Gbps Fibre Channel switching module (DS-X9224-96K9)

–

48-port 8-Gbps Fibre Channel switching module (DS-X9248-96K9)

–

4/44-port Host Optimized 8-Gbps Fibre Channel switching module (DS-X9248-48K9)

Conditions: This issue occurs after a nondisruptive upgrade to Cisco NX-OS Release 5.2(6x) or

Release 5.2(8), and a link flap occurs on the ports.

Workaround: This issue is resolved.

• CSCue12091

Symptom: While using the Cisco MDS IP over Fibre Channel (IPFC) function for the I/O

Accelerator (IOA) cluster management, the FC port channels between the IOA sites fail.

Workaround: This issue is resolved.

• CSCue47831

Symptom: While performing an In Service Software Upgrade (ISSU) on the Cisco MDS 9513

switch, the syslogd process crashes.
