Installing a Hotfix on a Single Chassis
This procedure describes the Full Connectivity installation of an Offline CPUSE package on a Single Chassis.
Important Notes
-
It is not supported to upgrade the CPUSE Agent on SGMs in a Security Group.
-
This procedure applies to Security Groups in Security Gateway mode and VSX mode.
In VSX mode, you must run all the commands in the context of VS0.
-
This procedure keeps the current connections.
-
If you finished a clean install on this chassis, then you can install a Jumbo Hotfix Accumulator only after you run the Gaia First Time Configuration Wizard.
-
Do not install the hotfix on all the SGMs at the same time.
If you do so with the command below, traffic stops passing through all SGMs until the hotfix is installed:
installer install <Number of CPUSE Package> member_ids all
-
With this procedure, you install the hotfix on half of the SGMs in a Security Group at one time.
The other half of the SGMs continues to handle traffic.
-
You install the hotfix on SGMs in a Logical Group "A" from an SGM that belongs to the Logical Group "A".
-
You install the hotfix on SGMs in a Logical Group "B" from an SGM that belongs to the Logical Group "B".
Example:
-
There are 8 SGMs in the chassis.
-
A Logical Group "A" comprises SGMs from 1_1 to 1_4.
-
A Logical Group "B" comprises SGMs from 1_5 to 1_8.
