Software Download Process
Downloading Software
The Cisco MDS NX-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.

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 Cisco DCNM for SAN
to perform the downgrade, enables the compatibility check. The check indicates if the upgrade can
happen nondisruptively or disruptively depending on the current configuration of your switch and the
reason.
Compatibility check is done:
Module bootable Impact Install-type Reason
------ -------- -------------- ------------ ------
1 yes non-disruptive rolling
2 yes disruptive rolling Hitless upgrade is not supported
3 yes disruptive rolling Hitless upgrade is not supported
4 yes non-disruptive rolling
5 yes non-disruptive reset
6 yes non-disruptive reset
At a minimum, you need to disable the default device alias distribution feature using the
no device-alias
distribute
command in global configuration mode. The
show incompatibility system bootflash:
system
image filename
command determines which additional features need to be disabled.
