Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 2.1(2b)

Determining the Software Version
Note We strongly recommend that you use the latest available software release supported by your vendor for
all Cisco MDS 9000 Family products.
To determine the version of the Cisco MDS SAN-OS software currently running on a Cisco MDS 9000
Family switch using the CLI, log into the switch and enter the show version EXEC command.
To determine the version of the Cisco MDS SAN-OS software currently running on a Cisco MDS 9000
Family switch using the Fabric Manager, view the Switches tab in the Information pane, locate the
switch using the IP address, logical name, or WWN, and check its version in the Release column.
Image Upgrade
The Cisco MDS SAN-OS software is designed for mission-critical high availability environments. To
realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend
that you install dual supervisor modules.
You can nondisruptively upgrade to Cisco MDS SAN-OS Release 2.1(2b) from any SAN-OS software
release beginning with Release 1.3(x). If you are running an older version of the SAN-OS, upgrade to
Release 1.3(x) and then Release 2.1(2b).
When downgrading from Cisco MDS SAN-OS Release 2.1(2b) to Release 1.3(x), you might need to
disable new features in Release 2.1(2b) for a nondisruptive downgrade. Issuing the install all command
from the CLI, or using Fabric Manager to perform the downgrade enables the compatibility check. The
check indicates that the downgrade is disruptive and the reason is “current running-config is not
supported by new image.”
Compatibility check is done:
Module bootable Impact Install-type Reason
------ -------- -------------- ------------ ------
2 yes disruptive reset Current running-config is not
supported by new image
3 yes disruptive reset Current running-config is not
supported by new image
5 yes disruptive reset Current running-config is not
supported by new image
6 yes disruptive reset Current running-config is not
supported by new image
