 The following actions are always recommended for ensuring host maintenance operations are carried out successfully:
 - **vSAN storage utilization:** To maintain Service Level Agreement (SLA), ensure that your vSphere cluster's storage space utilization remains below 75%. If the utilization exceeds 75%, upgrades may take longer than expected or fail entirely. If your storage utilization exceeds 75%, consider adding a node to expand the cluster and prevent potential downtime during upgrades.
 - **Distributed Resource Scheduler (DRS) rules:** DRS VM-VM anti-affinity rules must be configured in a way to have at least (N+1) hosts in the cluster, where N is the number of VMs part of DRS rule.

 - **Orphaned VMs:** In the case of an orphaned virtual machine, the Virtual Machine (VM) needs to be either re-registered if possible (if it hasn't been deleted) or removed from inventory. For more information, see [Broadcom KB article](https://knowledge.broadcom.com/external/article/312831/virtual-machines-appear-as-invalid-or-or.html).
 - **SCSI shared controller:** When using SCSI bus sharing use with bus type as "Physical" for VMs. VMs connected to Virtual SCSCI controllers will be powered-off. For more information, see [Broadcom KB article](https://knowledge.broadcom.com/external/article?legacyId=2147661).
 - **Third-party VMs & applications:** For third-party VMs & applications:

     - Ensure that the VM isn’t installed with a VM-Host "Must run" DRS rule. Additionally, verify that these applications are compatible with upcoming versions of the VMware stack.
     - Consult with your solution vendor and update in advance if necessary to maintain compatibility post-upgrade.
