File synchronization between the management and interface modules

An interface module can have two IronWare images: primary and secondary. These images contain

the layer 1 – 3 software that the interface modules run. These images reside in the interface

module’s flash memory. Either the primary or secondary image is run by the interface module from

this location.

If you copy the primary or secondary IronWare image to all interface modules using the copy

command with the all keyword, the management module makes a copy of the file and stores it in

its code flash under the names lp-primary-0 or lp-secondary-0. The images are stored in this

location only and are not run by the management module or the interface modules. If you copy the

primary or secondary IronWare image to a specified chassis slot using the copy command with the

<chassis-slot-number> parameter, the management module does not make a copy of the file.

If the management module has a copy of the primary or secondary IronWare image in its code

flash, by default, the BigIron RX Series system synchronizes or prompts you to synchronize the

interface modules IronWare images between the management module and the interface modules

during bootup. When the BigIron RX Series synchronizes the IronWare images, the management

module copies the IronWare images from its code flash to the interface modules’ code flash (the

interface modules’ default boot source).

The system allows you to manage synchronization of the IronWare images between management

and interface modules in the following situations:

•You are prompted to synchronize the IronWare images during bootup.

•You want to initiate an immediate synchronization; for example, you want an immediate update

of the IronWare images on one or all interface modules.

•You want to disable synchronization; for example, you have upgraded the IronWare image of

one interface module but want to continue running the older image on all other interface

modules.

The following section discuss how to manage the IronWare image synchronization in these

situations.

By default, the BigIron RX Series checks the IronWare images in the interface module’s flash

memory during boot to ensure they are is the same as the IronWare images in the management

module’s flash memory. If an interface module does not have an IronWare image, the system

automatically downloads the image from the management module’s flash memory to the interface

module’s flash memory.

If an interface module has different IronWare images, the system prompts you to do the following:

•If you want to update the primary and secondary IronWare images in the interface module’s

flash memory with the images in the management module’s flash memory, enter the lp

cont-boot sync <slot-number> command at the Privileged EXEC prompt.

•If you want to retain the IronWare images in the interface module’s flash memory, enter the lp

cont-boot no-sync <slot-number> command at the Privileged EXEC prompt.
