Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 3.3(4)
OL-14116-12
Limitations and Restrictions
These default settings are applied when a VSAN is created. However, the settings will not take effect on
VSAN 1, because it exists prior to running the setup script. Therefore, when you need these settings for
VSAN 1, you must explicitly issue the following commands:
• zone default-zone permit vsan 1
• zoneset distribute full vsan 1
• zone mode enhanced vsan 1
Running Storage Applications on the MSM-18/4
The Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4) does not support multiple, concurrent
storage applications. Only one application, such as SME or DMM, can run on the MSM-18/4 at a time.
Compatibility of Fabric Manager and Data Mobility Manager
Cisco Fabric Manager in any MDS NX-OS 4.1(x) release does not support Data Mobility Manager
(DMM) in any SAN-OS 3.3(x) release or in any 3.2(x) release. To use the Cisco Fabric Manager GUI
for DMM, both Fabric Manager and DMM must be running NX-OS or SAN-OS software from the same
release series.
A Supervisor-2 Module Might Reset in Switches Running SAN-OS Release
3.2(x)
An MDS 9000 switch with a Supervisor-2 module might switch over to the standby supervisor module
with a reset reason of Kernel Panic. Although there is no workaround for this issue, it happens very
rarely. Additional instrumentation and checks have been added to SAN-OS Release 3.4(x) and to NX-OS
Release 4.2(x) to ensure that kernel panic does not occur. DDTS CSCsx18173 describes this issue.
Limited ISSU Support on the MDS 9222i Switch
An in-service software upgrade (ISSU) from SAN-OS Release 3.3(4) to NX-OS Release 4.1(1b) or to
NX-OS Release 4.1(1c) is not supported on the MDS 9222i switch. This limitation applies only to the
MDS 9222i switch. You can perform an ISSU from SAN-OS Release 3.3(4) to NX-OS Release 4.1(1b)
or NX-OS Release 4.1(1c) on other MDS switches.
ISSU upgrades from SAN-OS Release 3.3(4) to NX-OS Release 4.1(3a) and to NX-OS Release 4.13(a)
are supported on the MDS 9222i switch.
