9000 Family switch using the CLI, log in to the switch and enter the show version EXEC command.
To determine the version of Cisco MDS NX-OS or 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.
Determining Software Version Compatibility
Table 7 lists the software versions that are compatible in a mixed SAN environment, the minimum
software versions that are supported, and the versions that have been tested. We recommend that you use
the latest software release supported by your vendor for all Cisco MDS 9000 Family products.

realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend
that you install dual supervisor modules.

See the following sections in this release note for details on how you can nondisruptively upgrade your
Cisco MDS 9000 switch. Issuing the install all command from the CLI, or using Fabric Manager to

nondisruptively or disruptively depending on the current configuration of your switch and the reason.
