VxBlock Central simplified upgrade VxBlock Central supports a simplified upgrade process for single-site environments. It does not apply to multisite enviroments. The upgrade is initiated from MSM and MSM in turn runs the upgrade on each of the Core VMs and MSP VMs. After the upgrade process begins: Do not add any VxBlock Central Core nodes to MSM VMs. Do not join any additional MSM VMs to an MSM cluster. The following are high-level steps required for a VxBlock Central simplified upgrade on a single-site cluster with a single MSM VM: Collect custom display properties if the system is single MSM. For more information refer to: Collecting the custom display names. Take a snapshot of the VMs. For more information see: Taking a snapshot of the VMs. Configure the NTP server. For more information see: Configuring the VM to use the NTP server. Ensure you have your MSP VM IP address and VxBlock Central Core root passwords. Run the VxBlock Central upgrade script from MSM. For more information refer to: Upgrading a single MSM VM. Reenter the custom display name. For more information refer to: Reentering the custom display names.
