Automatic Upgrade During Node Addition; Upgrading In Service Mode - Cisco MDS 9216 Configuration Manual

Chapter 8 Upgrading CSM Software

Automatic Upgrade during Node Addition

If a node is running a SVC software version which is different from the cluster version, and that node is
added to the cluster, the config node automatically downloads the cluster software to the new node. If
the cluster software is not compatible with the software running on the switch that contains the new node,
the add node operation will fail.

Upgrading in Service Mode

Service mode software upgrade provides a recovery alternative if the cluster cannot accept a normal
software upgrade. A single node is placed in service access mode to perform a service mode software
upgrade. This is in contrast to the normal method for upgrading all the nodes in the cluster.
This upgrade process is only to be used by experienced switch administrators under the care of customer

support representatives.
To upgrade a single node in service mode, follow these steps.
Issue the node svc slot/node servicemode command on the required node to place the node in service

This command checks if the new SVC software image is compatible with the running switch software
and the running SVC software.
If any of these compatibility checks fail, then node upgrade fails with the appropriate error message to
the user.
Issue the show node local command in SVC configuration mode to verify that the required node is
