VM migration in VSAN

[BruceHB]

I try to shutdown one hosts from VSAN cluster then I have to manually migrate VMs on the node to others for standard license.

Then the VM migration type has three option:

change compute resource only

change storage resource only

change both compute resource and storage

For host shutdown, I can confirm we must change compute resource.

Anyone can help explain whether it is necessary to change storage resource since it is VSAN?

BTW, What the migration type the DRS chooses in enterprise license?

Best Regards,

Bruce

To migrate the virtual machines from iSCSI/FC/NFS to vSAN if they are on different cluster:

Present current SAN storage to new ESXi vSAN Hosts.

Shutdown virtual machine and remove it from Inventory on old cluster.

Re-register the virtual machine on a new vSAN host cluster.

Using storage vMotion migrate the VMs to vSAN.

After migrating all virtual machines, un-present vSAN LUN's.

Please mark this as correct if this answers and helps you .

Hello Bruce,

No, it is not necessary to change the storage resource (unless you want to migrate the data off vsanDatastore).

The Maintenance Mode (MM) option used will determine whether some/all of the data-components remain accessible on the other nodes - e.g. host placed in MM with 'Full Data Evacuation' will move all the data off the node (provided there are enough available Fault Domains and space), 'Ensure Accessibility' will check that there is another replica of the data available on another node(s) and thus the data Object (e.g. vmdk) remains accessible without this node, MM with 'No Action' will not check that the data will remain accessible.

DRS uses 'change compute resource only'.
