Managing interface modules 7If you copy the primary or secondary image to all interface modules using the copy command withthe all keyword, the management module makes a copy of the file and stores it in code flash underthe names lp-primary-0 or lp-secondary-0. The images are stored in this location only and are notrun by the management module or the interface modules. If you copy the primary or secondaryimage to a specified device slot using the copy command with the parameter, the management module does not make a copy of the file.If the management module has a copy of the primary or secondary image in code flash, by default,the router synchronizes, or prompts you to synchronize, images between the management moduleand the interface modules during the boot process. When the router synchronizes the images, themanagement module copies the images from flash memory to the flash memory on the interfacemodule (the default boot source for the interface modules).You can manage synchronization of the software images between management and interfacemodules in the following situations:• You are prompted to synchronize the software images during the boot process.• You want to initiate an immediate synchronization; for example, you want an immediate updateof the software images on one or all interface modules.• You want to disable synchronization; for example, you have upgraded the image of oneinterface module but want to continue running the older image on all other interface modules.The following sections discuss how to manage software image synchronization in these situations.Synchronizing the software image on interface modules during the boot processBy default, the router checks the software images in the flash memory on interface modules duringthe boot process to see if they are the same as the images in the flash memory on themanagement module. If an interface module does not have a software image, the systemautomatically downloads the image from the management module to the interface module.If an interface module has an image that is different from that on the management module, thesystem prompts you to take one of the following steps:• To update the primary and secondary images on the interface module with the images on themanagement module, enter the lp cont-boot sync command at the PrivilegedEXEC prompt.• To retain the software images on the interface module, enter the lp cont-boot no-sync command at the Privileged EXEC prompt.Syntax: lp cont-boot sync Syntax: lp cont-boot no-sync Specifying an immediate synchronizationTo immediately synchronize software images between the management module and one or allinterface modules, enter the following command at the Privileged EXEC level.Brocade# lp sync allSyntax: lp sync [all | ]• The all keyword indicates that the immediate synchronization applies to all interface modulesin the router.• The parameter specifies the slot number that contains the interface module towhich the immediate synchronization applies. You can specify 1 – 4 for 4-slot devices, 1 – 8 for8-slot devices, 1 – 16 for 16-slot devices, or 1 – 32 for 32-slot devices.Brocade MLX Series and Brocade NetIron XMR Hardware Installation Guide 33953-1002373-02
