3–6 Compaq StorageWorks HSG80 Array Controller ACS Version 8.5 Maintenance and Service Guide
14. Use KERMIT to transfer the binary image from the PC to the controller.
When the download is complete, CLCP automatically writes the new image to the
program card and restarts the controller.
15. Verify that the controller is running the new software version with the following
command:
SHOW THIS CONTROLLER
16. If the program card is equipped with a write-protection switch (see Figure 3–2), enable
write-protection by sliding the switch to the “write protected” position.
17. Replace the program card ESD cover.
18. Repeat the procedure to upgrade the “other controller” in dual-redundant controller
subsystems.
19. Mount the storage units in 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
Use the following steps to install a software patch:
1. Obtain the patch file from a customer service representative or via the Internet at
http://www.storage.digital.com/menusupport.htm.
2. Connect a PC or terminal to the controller maintenance port.
3. From the host console, quiesce all port activity.
