MOP to increase vCPUs Prior to Upgrading SBC SWe on VMware or KVM Hypervisor (8.2.4R002)

The SBC Core release 8.2 includes a feature that extends the use of hyper-threading to SBC SWe when it is installed on either the VMware or KVM Hypervisor platform. To take advantage of the performance improvements provided by hyper-threading, you must increase (double) the number of vCPUs configured in the VM prior to software upgrade. When upgrading, modify the upgrade process to incorporate the following additional steps:

If upgrading SBC SWe KVM Hypervisor or VMware from pre-07.01.00R000 release to 07.01.00R000 or higher: If upgrading vCPUs from less than 10 to 10 or more, use the procedure below:

1. On the VMware platform only, before beginning the upgrade, disable the CPU reservation check inside the guest by renaming the file: vmware-toolbox-cmd. For example, issue the following command:
   mv /usr/bin/vmware-toolbox-cmd /usr/bin/vmware-toolbox-cmd.bak
2. Stop standby SBC by issuing "sbxstop". Wait until the SBC processes stop.
3. Shutdown the standby SBC by issuing "power off" command.
4. Increase vCPU count on the powered off standby SBC.
5. Stop active SBC by issuing "sbxstop". Wait until the SBC processes stop. Note that this is service affecting since both SBCs are stopped now.
6. Shutdown the active SBC by issuing "power off" command.
7. Increase vCPU count on the powered off active SBC.
8. Power on an active SBC. Wait for the SBC to fully start as active.
9. Power on a standby SBC. The SBCs should start as standby and get in sync with active SBC.
