Uninstalling a patch step by step
To uninstall a patch by using the step-by-step method, you must first stop running the patch and then
remove it from the patch memory area.
Stopping running patches
After you stop running a patch, the patch state becomes DEACTIVE, and the system runs the way it did
before it was installed with the patch.
To stop running patches:
Step Command
1.
Enter system view.
system-view
2.
Stop running patches.
•
In standalone mode:
patch deactive patch-number slot slot-number
•
In IRF mode:
patch deactive patch-number chassis
chassis-number slot slot-number
Removing patches from the patch memory area
After being removed from the patch memory area, a patch is still retained in IDLE state in the storage
medium. The system runs in the way before it was installed with the patch.
In an IRF fabric, H3C recommends that you uninstall all patches by using the undo patch install
command.
To remove patches:
Step Command
1.
Enter system view.
system-view
2.
Remove patches from the patch memory area.

Upgrading MBUS daughter card software
Typically, the MBUS daughter card software is automatically upgraded when the system software image
is upgraded. If the auto-upgrade fails, use the mbus update command to upgrade it.
To ensure a successful upgrade, follow these guidelines:
•
In an IRF fabric, save the upgrade file on the active MPU in the same chassis as the MBUS daughter
card. If you are upgrading the master switch, the file can also be saved on the standby MPU.
•
Make sure no one performs any of the following operations during the upgrade:
{
Perform an active/standby switchover.
{
Power off or reboot the switch.
{
Reboot or swap the active MPU.
