If your virtualization platform is VMware ESXi, confirm the following configuration items based on the actual software parameters and perform the operations as needed.
Update I/O rerouting and SCVM auto-restart scripts: Mandatory. You must update the I/O rerouting and SCVM auto-restart script after the ACOS upgrade is complete.
Adjust SCVM latency sensitivity: Optional. The latency sensitivity option of the virtual machine where the SCVM resides may not have been reconfigured before the upgrade. For users with high performance requirements, it is recommended to adjust the virtual machine latency sensitivity from Default to High. If users have low or no performance requirements, this option can be ignored.
Modify the HA policy of the virtual machine: Optional. If the virtual machine's HA policy is not adjusted before the cluster upgrade and the MisC.APDHandlingEnable parameter value is set to 1, it is recommended to adjust the policy after the upgrade.
Upgrading advanced monitoring: Optional. If the advanced monitoring version corresponding to the upgrade target version is inconsistent with the advanced monitoring version before the upgrade, it is necessary to manually upgrade the advanced monitoring application to the latest version; otherwise, no action is required.
