Run the vsan.host_claim_disks_differently RVC command to mark storage devices as flash, capacity flash, or magnetic disk (HDD).
You can use the RVC tool to tag flash devices as capacity devices either individually, or in a batch by specifying the model of the device. When you want to tag flash devices as capacity devices you can include them in all-flash disk groups.
For information about the RVC commands for Virtual SAN management, see the
RVC Command Reference Guide.
Note: The
vsan.host_claim_disks_differently command does not check the device type before tagging them. The command tags any device that you append with the
capacity_flash command option, including the magnetic disks and devices that are already in use. Make sure you verify the device status before tagging.
Prerequisites
- Verify that you are using Virtual SAN version 6.5 or later.
- Verify that SSH is enabled on the vCenter Server Appliance.
Procedure
What to do next
