Unable to migrate (compute and storage vmotion) a VM from one vSAN Cluster to another vSAN Cluster

Products

• VMware vSAN

Issue/Introduction

Doing compute and storage vmotion of a VM from one vSAN cluster to other vSAN cluster, gives below warning in the migrate wizard in vCenter UI

• Datastore does not match current VM policy.
• Policy specified requires 6 fault domains contributing all-flash storage, but only 5 found.
  
  

Environment

VMware vSAN 7.x
VMware vSAN 8.x

Cause

This is due to an insufficient number of Fault domain or Standalone hosts in the target/destination vSAN cluster where we are trying to migrate the VM.

Storage Policy	Minimum number of Standalone host /Fault Domain
FTT-1 RAID-1	3
FTT-2 RAID-1	5
FTT-3 RAID-1	7
FTT-1 RAID-5	4
FTT-2 RAID-6	6

 

Resolution

Change the VM policy in the migration wizard which can satisfy the VM creation in target/destination vSAN cluster
