First of all I would like to show my VMware lab Datastores and all the datastores shows as “Non-SSD” datastores.
You can verify this whether this datastore device is detecting as SSDs from the command line
SSH in to one of your ESXi host and type ” esxcli storage core device list” command and verify the SSD device status (Note: This is an output for eui.3fca7e21c5941116 and I’m going to tag eui.2de85804589092cd device, this is a sample output and you need to identify the correct device from the device ID).
In my case datastore which I’m going to manually tag as SSD shows as “Is SSD: false” state
Type ” esxcli storage nmp device list ” to Identify the SATP plugin of the device, in my case SATP plugin is ” VMW_SATP_DEFAULT_AA “
The next step is to add a PSA claim rule to mark the device as SSD.
Type: esxcli storage nmp satp rule add -s <your storage array type> –device <device id> –option=enable_ssd
Now unclaim the device
Type: esxcli storage core claiming unclaim –type device –device <device id>
Reclaim the device using load and run command
Check the SSD status of the device
Type: esxcli storage core device list -d <device id>
Now check the status in vSphere console, you can see the Datastore as a SSD datastore
So now we successfully tagged the Storage Device as a SSD device.
