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.
If the standby supervisor module bootflash: filesystem does not have sufficient space to accept the
updated image.
If the specified system and kickstart images are not compatible.
If the install all command is issued on the standby supervisor module.
If the install all command does not reference the default bootflash: in a dual supervisor module
configuration.
If the fabric or switch is configured while the upgrade is in progress.
If a module is removed while the upgrade is in progress.
If the switch has any power disruption while the upgrade is in progress.
If the entire path for the remote location is not specified accurately.
If images are incompatible after an upgrade. For example, a switching module image may be
incompatible with the system image, or a kickstart image may be incompatible with a system image.
This is also identified by the show install all impact command in the compatibility check section
of the output (under the Bootable column).
