If you plan to migrate the virtual machine clustering with shared VMDK from vSphere 6.7 to 7.0, please prepare the requirements of clustered VMDK on vSphere 7.0, then you can migrate the virtual machine into the vSphere 7.0 otherwise the clustering services of virtual machine cannot start up.
vSphere 7.0 introduces support for the use of VMDKs on clustered datastore as shared disk resources for a WSFC. Using VMDKs reduces the extra overhead to manage the virtual disks compared to pRDMs. You can enable clustered VMDK support when you create a new VMFS6 datastore, or enable clustered VMDK on an existing VMFS6 datastore. Before enabling clustered VMDK support, ensure all hosts connected to the datastore are using ESXi 7.0 or later and are managed by vCenter 7.0 or later.
Under General go to the Datastore Capabilities section. Click the Enable button for Clustered VMDK.
You must follow these requirements when using Clustered VMDKs with WSFC.
- You must set the Windows Cluster Parameter QuorumArbitrationTimeMax to 60.
- The physical disk that virtual disks are stored on must support ATS SCSI commands.
- The physical disk must support SCSI-3 Persistent Reservations, specifically Write Exclusive All Registrants (WEAR) type reservations.
- VMDKs must be Eager Zeroed Thick Provisioned.
- Storage devices can be claimed by VMware Native Multipathing Plugin (NMP) or by any other third-party MultiPathing Plugin (MPP). Check with vendors regarding the support for Clustered VMDK before using a vendor’s third-party MultiPathing Plugin (MPP).
