Upgrading the Subsystem
Using CLCP to Install, Delete, and List Software
Patches
Use CLCP to manage software patches. These small programming changes are placed
into the controller non-volatile memory and become active upon restarting the
controller.
Keep the following points in mind while installing or deleting patches:
•
Patches are associated with specific software versions. CLCP verifies the patch
against the currently installed version.
•
Patches are sequential: patch one must be entered before patch two, and so on.
•
Deleting one patch also deletes all higher-numbered patches. For example, if
deleting patch two, it also automatically deletes patches three, four, and so on.
•
Controllers in a dual-redundant configuration must have the same patches. Install
patches into each controller separately.
Installing a Software Patch

1. Obtain the patch file from a customer service representative or via the Internet at
