Managing clusters

The topics in this section describe how to use Lenovo XClarity Integrator for managing clusters.

Procedure

Complete the following steps to view the Lenovo XClarity Integrator cluster management functions.

  1. Select a cluster from the vCenter inventory tree.
  2. Click the Configure tab.
    On the left navigation pane, select one of the following functions under Lenovo XClarity:

    • Rolling Update

    • Rolling Reboot

  • Working with the vSphere Lifecycle Manager function
    When users manage the cluster by using a single image, it is recommended to use the vSphere Lifecycle Manager function.
  • Working with the Proactive Hardware Management function
    Introduced in vSphere 8.0u3, Proactive Hardware Management(PHM) is a feature to notify on a failing disk drive prior to vSAN hitting read/write issues, so users would have recommendations from VMware and Lenovo in the event of a disk health issue.
  • Working with the Rolling System Update function
    Rolling System Update (RSU) provides a nondisruptive approach to firmware updates. RSU fully manages firmware by orchestrating "rolling" updates, leveraging dynamic virtual machine movement within a defined VMware cluster, completing the whole update process, including ESXi host restart automatically, without any interruption to application services running on the host.
  • Working with the Rolling System Reboot function
    The Rolling System Reboot (RSR) function restarts a server while a system continues running without interrupting any running application services by dynamic VM migration.
  • Working with Proactive HA
    VMware vSphere v6.5 adds the new Proactive HA feature, which is an enhancement of the original High Availability (HA) feature. Lenovo XClarity Integrator for VMware vCenter supports the Proactive HA feature by registering a Lenovo Proactive HA provider to VMware vCenter.
  • Managing hardware events
    Hardware events and alarms are integrated into vCenter. Lenovo XClarity Integrator for VMware vCenter loads events from out-of-band (OOB) BMC nodes into the vCenter server, allowing administrators to view and manage them from vSphere Client. This provides administrators with a single, heterogeneous view of all host system events within the managed environment.
