Essential Upgrade Prerequisites
Before attempting to migrate to any software image version, follow these guidelines:
•Customer Service
Before performing any software upgrade, contact your respective customer service representative to
review your software upgrade requirements and to provide recommendations based on your current
operating environment.
Note If you purchased Cisco support through a Cisco reseller, contact the reseller directly. If you
purchased support directly from Cisco Systems, contact Cisco Technical Support at this URL:

•Scheduling
Schedule the upgrade when the fabric is stable and steady. Ensure that everyone who has access to
the switch or the network is not configuring the switch or the network during this time. All
configurations are disallowed at this time.
•Space
Verify that sufficient space is available in the location where you are copying the images. This
location includes the active and standby supervisor modules or bootflash: (internal to the switch).
–
Standby supervisor module bootflash: directory (see the ).
–
Internal bootflash offers approximately 200 MB of user space.
•Hardware
Avoid power interruption during any install procedure. These kinds of problems can corrupt the
software image.
•Connectivity (to retrieve images from remote servers)
–
Configure the IP address for the 10/100BASE-T Ethernet port connection (interface mgmt0).
–
Ensure the switch has a route to the remote server. The switch and the remote server must be in
the same subnetwork if you do not have a router to route traffic between subnets.
–
Ensure any standby supervisor modules are physically connected with a path to the remote
servers.
•Images
–
Ensure that the specified Cisco MDS SAN-OS system and kickstart images are compatible with
each other.
–
If the kickstart image is not specified, the switch uses the current running kickstart image.
–
If you specify a different system image, ensure that it is compatible with the running kickstart
image.
–
Retrieve images in one of two ways:
Locally—images are locally available on the switch.
