)Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.0(1a)
OL-21012-01
Caveats
– If you perform a nondisruptive upgrade or downgrade from a release that contains a fix to a
release that does not contain the fix, you need to reload each module affected by this issue.
– If you have a Cisco MDS 9222i swtich that is affected by this issue, and you perform a
nondisruptive upgrade or downgrade from a release that contains a fix to a release that does not
contain the fix, you need to reload the switch.
• CSCsq20408
Symptom: The show startup command displays aspects of the running configuration when
SANTap is configured and/or SANTap objects are created. When a user creates objects such as a
CVT or DVT, the configuration is showing in the running-configuration and in the
startup-configuration without copying the configuration into the startup-configuration.
Workaround: Issue a copy running-config startup-config command whenever you create objects
such as a CVT or DVT so that the running-configuration and startup-configuration are synchronized.
• CSCsy37951
Symptom: The Trunking F PortChannels feature is not available in NX-OS Release 4.1(1x);
however, a downgrade from Release 4.1(3a) or later to Release 4.1(1x) is nondisruptive, even when
the Trunking F PortChannels feature is enabled (using the feature fport-channel-trunk command)
while running Release 4.1(3a) or later.
Workaround: If a downgrade to Release 4.1(1x) is performed when the Trunking F PortChannels
feature is enabled, the switch will be in an inconsistent state. You must reload the switch after a
downgrade to Release 4.1(1x).
• CSCte93219
Symptom: If you have an MDS 9000 switch running NX-OS Release 5.0(1a) and also running
DMM or Secure Erase, when you downgrade to an NX-OS 4.x release, you see the following errors:
– syslog messages display with the error string PSS_VERSION_MISMATCH for the
configuration of an internal service (ilc_helper)
– After the ISSD completes and the switch comes up with the NX-OS 4.x release, an internal
process (ilc_helper) fails.
Workaround: None.
• CSCtg61169
Symptom: Users are no longer able to log in to an MDS 9000 switch via SSH. The following error
is seen in the log file:
unable to lock password file
At the same time the /dev/root file system is 100 percent in use.
This symptom might occur if there are many HTTP requests that go to the built-in MDS web server.
The log file of the service continues to grow until it consumes all available space in /dev/root.
Workaround: Use the dbug plugin and empty the file with the following command:
cat /dev/null > /var/log/thttpd.log.CSCtn68418
• CSCtn68418
Symptom: When you try to save a configuration, you might see the following message:
