VMware RDM

Locate VMware RDMs through the vSphere Client

[{"selector":"#anim-27fd79e0-a48f-471d-b60e-be5b9aeeb344","keyframes":[{"transform":"scale(1)","offset":0},{"transform":"scale(1.5)","offset":0.33},{"transform":"scale(0.95)","offset":0.66},{"transform":"scale(1)","offset":1}],"delay":0,"duration":1450,"easing":"ease-in-out","fill":"both","iterations":1}]

Step 2. Select a Virtual Machine.

Step 4. Choose hard disks in the Virtual Hardware list with mapped raw LUNs, and you'll find the RDM virtual disk mapping file path and the associated SCSI device name starting with vml.xxxxxxx.

Identify VMware RDMs using the ESXCLI

[{"selector":"#anim-0403166b-938c-443b-9f00-cc48b4b2dedc","keyframes":[{"transform":"scale(1)","offset":0},{"transform":"scale(1.5)","offset":0.33},{"transform":"scale(0.95)","offset":0.66},{"transform":"scale(1)","offset":1}],"delay":0,"duration":1450,"easing":"ease-in-out","fill":"both","iterations":1}]

Step 2. Run the following commands

[{"selector":"#anim-e5d03efd-44d4-4c9f-a80b-288ba76e83fe","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-f374fb8e-4f43-4fdb-b1a8-23bb4f6ef73d","keyframes":{"transform":["translate3d(-118.03797%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] Get-VM | Get-HardDisk -DiskType "RawPhysical","RawVirtual" | Select Parent,Name,DiskType,ScsiCanonicalName,DeviceName | ft

Step 3. You'll receive a list of virtual machines with RDM disks hosted on the identical ESXi host.

You should run this on the VMs for RDM disk checks, but it might not always work. ESXiCLI is the best choice for checking RDM disks in VMware VMs.
