Non-Disruptive Upgrades on Fabric and Modular Switches

If there is insufficient space available in the system to load the new images, then you will be notified
•
via the compatibility table. At this point, you need to either abort the upgrade or proceed with a
disruptive upgrade.
Issue the no logging level all command before the commencing with the upgrade. Failing to issue
•
this command could result in a failure due to the debug system log messages being printed and
potentially resulting in control plane downtime exceeding 80 seconds.
If VRRP is running on the mgmt0 interface, and the switch being upgraded is the master, then a new
•
master is selected. This cannot be avoided because the mgmt0 interface goes down when the control
plane goes down.
On the Cisco MDS 18/4-port multiservice module, upgrades of the 4 Gigabit Ethernet ports for the
•
hybrid Supervisor 18/4 line card will be disruptive.
To ensure that you can view the entire upgrade process, it is recommended that you perform the upgrade
via the console port; performing the upgrade in this way also enables you to log your session to a file (in
case you need it later for troubleshooting). Also, telnet sessions are lost when the switch is rebooted, so
if you wish to view the process in its entirety, use the console port instead.

Do you want to continue with the installation (y/n)?
Before performing an upgrade, you may wish to use the show install all impact command to view the
effect of updating the system from the running image to another specified image.
switch# show install all impact kickstart bootflash:boot-fs9124 system bootflash:isan-164
Verifying image bootflash:/boot-fs9124 for boot variable "kickstart".
