Downloading a New Software Version
Downloading a New Software Version
File Synchronization after Downloading
After downloading a new software version to either the primary or secondary
flash of the active management module, the software version is immediately
copied to the corresponding flash (primary or secondary) of the standby
module unless the standby module failed selftest or redundancy was disabled
with the
no redundancy management-module
command.
The configuration files, including which configuration file to use for that flash
image, are synchronized. For example, if the active management module is
using config1, the standby module will also be synchronized to use config1.
N o t e
See “Setting the Default Flash for Boot” on page 15-31 for information about
testing new software versions.
After installing the new software to the active management module, wait a
few minutes, and then verify that the standby module has been synchronized
with the new software as well (use the
show flash
command). If the default
flash for boot has been set correctly, you can start the standby management
module on the new software by executing the
boot standby
command. This
does not interrupt current switch operations yet. After the standby
management module has rebooted and is ready for takeover in standby mode
