Firmware Download
84 Fabric OS Procedures Version 3.1.x/4.1.x User Guide
By default, firmwaredownload will do a full install of the whole firmware
regardless of whether a package is already current or not. In Incremental Install
Upgrade Mode, the names of packages are compared to what is already installed
on the switch; only the packages that are different from those already stored or not
on the switch yet are installed.
Use the -i option to do an incremental firmware download.
Downloading Firmware to a Single CP on a Core Switch 2/64
Though it is possible to download firmware to one CP at a time, is not
recommended. We recommend that both CPs be upgraded at the same time so
they are consistent.
Note: This is the procedure to follow if your
Core Switch 2/64
is running version
4.0.0c or less.
The following procedure enables single mode on aCore Switch 2/64 series switch.
Single Mode allows a user to:
■ Upgrade to a single CP on aCore Switch 2/64 switch
■ Select a full-install, auto-reboot, and auto-commit (only the "-s" option is
required on the command line).
■ Upgrade a Core Switch 2/64 that is running v4.0.0c or less.
To enable Single Mode on a Core Switch 2/64:
1. Telnet in to the Core Switch 2/64 as admin.
Example
Note: In this example, the Active CP is CP1, and the Standby CP is CP0.
2. Execute the hashow command to determine which CP is the Active and
which is the Standby.
