The install all command automatically verifies if the standby supervisor module is functioning (if
present). If it is not functioning, it reloads that module and uses the reload module slot force-dnld
command to force it to function.

You can upgrade the entire switch using just one procedurecommand.
You can receive descriptive information on the intended changes to your system before you continue
with the installation.
You have the option to cancel the command. Once the effects of the command are presented, you
can continue or cancel when you see this question (the default is no):
Do you want to continue (y/n) [n] :y
You can upgrade the entire switch using the least disruptive procedure.
You can see the progress of this command on the console, Telnet, and SSH screens:
– After a switchover process, you can see the progress from both the supervisor modules.
Before a switchover process, you can only see the progress from the active supervisor module.
–
The command automatically checks the image integrity. This includes the running kickstart and
system images.
The command performs a platform validity check to verify that a wrong image is not used—for
example, to check if an MDS 9500 Series image is used inadvertently to upgrade an MDS 9200
Series switch.
The Ctrl-c escape sequence gracefully ends the command. The command sequence completes the
update step in progress and returns to the switch prompt. (Other upgrade steps cannot be ended using
Ctrl-c.)
After issuing the command, if any step in the sequence fails, the command completes the step in
progress and ends.
For example, if a switching module fails to be updated for any reason (for example, due to an
unstable fabric state), then the command sequence disruptively updates that module and ends. In
such cases, you can verify the problem on the affected switching module and upgrade the other
switching modules.
