Cisco MDS 9000 Family Fabric Manager Configuration Guide
OL-17256-03, Cisco MDS NX-OS Release 4.x
Chapter 15 Software Images
Essential Upgrade Prerequisites
Note 1000 BASE-T Ethernet is only available on Supervisor-2 modules.
–
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.
• Images
–
Ensure that the specified 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:
Local file—Images are locally available on the switch.
Network file—Images are in a remote location and the user specifies the destination using the
remote server parameters and the file name to be used locally.
• Terminology
Table 15-4 summarizes terms used in this chapter with specific reference to the install and upgrade
process.
• Tools
–
Verify connectivity to the remote server by clicking Verify Remote Server in the Software
Install Wizard in Fabric Manager.
–
Ensure that the required space is available for the image files to be copied by using Software
Install Wizard to check free disk space.
–
We recommend the Software Install Wizard in Fabric Manager to upgrade your software. This
wizard upgrades all modules in any Cisco MDS 9000 Family switch (see the “Benefits of Using
the Software Install Wizard” section on page 15-6).
–
Run only one installation on a switch at any time.
–
Do not issue another command while running the installation.
–
Do the installation on the active supervisor module, not the standby supervisor module.
