Managing interface modules
7
If you copy the primary or secondary 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 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
image to a specified device slot using the copy command with the <
device-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 image in code flash, by default,
the router synchronizes, or prompts you to synchronize, images between the management module
and the interface modules during the boot process. When the router synchronizes the images, the
management module copies the images from flash memory to the flash memory on the interface
module (the default boot source for the interface modules).
You can manage synchronization of the software images between management and interface
modules 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 update
of the software images on one or all interface modules.
•
You want to disable synchronization; for example, you have upgraded the image of one
interface 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 process
By default, the router checks the software images in the flash memory on interface modules during
the boot process to see if they are the same as the images in the flash memory on the
management module. If an interface module does not have a software image, the system
automatically 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, the
system prompts you to take one of the following steps:
•
To update the primary and secondary images on the interface module with the images on the
management module, enter the lp cont-boot sync <
slot-number > command at the Privileged
EXEC prompt.
•
To retain the software images on the interface module, enter the lp cont-boot no-sync
<
slot-number > command at the Privileged EXEC prompt.
Syntax: lp cont-boot sync < slot-number >
Syntax: lp cont-boot no-sync < slot-number >
Specifying an immediate synchronization
To immediately synchronize software images between the management module and one or all
interface modules, enter the following command at the Privileged EXEC level.
Brocade# lp sync all
Syntax: lp sync [all | <slot-number> ]
•
The all keyword indicates that the immediate synchronization applies to all interface modules
in the router.
•
The < slot-number > parameter specifies the slot number that contains the interface module to
which the immediate synchronization applies. You can specify 1 – 4 for 4-slot devices, 1 – 8 for
8-slot devices, 1 – 16 for 16-slot devices, or 1 – 32 for 32-slot devices.
