Performing a Nondisruptive Upgrade on a Fabric Switch

You can use the Software Install Wizard to perform nondisruptive upgrades on Cisco MDS 9124 Fabric
Switches. See
the Sofware Install Wizard.
Caution It is recommended that you enable port-fast on the Ethernet interface of the Catalyst switch to which the
management interface of the fabric switch is connected. This is to avoid spanning-tree convergence time
on the Catalyst switch and packets from the fabric switch are forwarded immediately during the
nondisruptive upgrade.
When selecting images during the upgrade, ASM-SFN and SSI are not supported on the Cisco MDS
Note
9124 Switch and the Cisco MDS 9134 Multilayer Fabric Switch.

Switch cabling

Addition or removal of physical devices
–
Configure the FSPF timers to the default value of 20 seconds.
If there are any CFS commits pending in the fabric, the upgrade is aborted.
If there is a zone server merge in progress, the upgrade is aborted.
Check whether there is sufficient space available in the system to load the new images using the
Software Install Wizard. At this point you need to either abort the upgrade or proceed with a
disruptive upgrade.
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.
