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: When a virtual machine (VM) moves to another partition, the VIO performs a LOGO

first and then with the same World Wide Name (WWN) from the new location does a fabric login

(FLOGI) or FDISC again. This occurs within 10 milliseconds to minimize downtime to the VM.

Workaround: None.

• CSCuf82609

Symptom: After an In Service Software Upgrade (ISSU) on the Cisco MDS 9222i switch, Cisco

Fabric Services (CFS) merge is initiated.

Workaround: None.

• CSCug36861

Symptom: The Cisco MDS 9222i switch drops packets as timeouts. The timeout drop occurs

periodically every 15 minutes.

Condition: When a user upgrades to Cisco MDS NX-OS Release 5.2(8) or 5.2(6b) from a preceding

version of Cisco MDS NX-OS software.

Workaround: None.

• CSCud32085

Symptom: On a Cisco MDS 9222i, Storage Media Encryption (SME) disk discovery fails to detect

any disk on the HP BladeSystem c7000 enclosure.

Condition: This occurs when a user attempts to perform the Add Disk Group operation by using

the Cisco Data Center Network Manager (DCNM) Web Client to configure SME.

Workaround: Remove the port channel trunk from the Fibre Channel link(s).

• CSCug64503

The following type of exceptions are logged in the module exception log in an unthrottled manner:

TBIRD_FWD_EBM_1_BASE_B_ECC_1ERR

TBIRD_FWD_EBM_1_BASE_A_ECC_1ERR

Condition: This occurs only in the Cisco MDS DS-X9232-256K9 and DS-X9248-256K9 modules.

Workaround: To clear the source of the messages, reload the module from which the messages are

incoming or upgrade to a succeeding version of Cisco MDS NX-OS software.

• CSCug67068

Symptom: On a Cisco MDS 9148 switch and MDS 9134 switch, an attempt to overwrite the Cisco

MDS NX-OS software image version fails with the following error:

?permission denied?

Condition: When a user login to the switch from Cisco Data Center Network Manager (DCNM) as

a non-root user.

Workaround: Login as a root user.

• CSCug76835

Symptom: Cisco MDS Generation 4 modules attempt to log several events to syslog buffer on the

supervisor.

Condition: Normal operation.

Workaround: Override the default embedded event manager (EEM) policy for the informational

level logging to syslog by using the event manager applet INFO_ERR-override override

__INFO_ERR command.
