Get-VM | Get-HardDisk | Where-Object | Select | Export-Csv C:\Users\Adil\Desktop\RDM-list.csv -NoTypeInformation Disk Type (Physical or Virtual compatibility).īefore you run this command, kindly connect to the vCenter Server or the ESXi host using the Connect-VIServer cmdlet. Select Use an existing Virtual Disk (please do not select Raw Device Mapping) Browse the datastore and select the VMDK file and click OK, followed by Next Select a SCSI Virtual Device Mode.The file length of the mapping is the same as the size of the raw LUN it points to. After this mapping is established, you can access the LUN as you would a normal VMFS virtual disk. The one-liner that I wrote will list the below details: Use the vmkfstools command to create a Raw Device Mapping (RDM) file on a VMFS volume and map a raw LUN to this file. I was looking at probably a one-liner which would list the Virtual Machine name along with the RDM details. I first performed a Google search and could find a few scripts available but most of them were lengthy and cumbersome. The customer wanted to perform a SAN to SAN migration and there were a lot of Virtual Machines with RDMs configured. Raw Device Mapping (RDM) is one way to pass a raw disk device directly through from the disk controller to the SoftNAS Cloud® VM in VMware. Right-click the Node B virtual machine and click Edit Settings. Ensure that you use the SCSI device that you need in step 6. In previous releases of VMware you had to create a raw mapping by cloning another virtual disk and importing it into the LUN. Add the RDM to the virtual machine as a new disk and select virtual compatibility mode (the naming of this option depends on the Esxi/Vcenter version used). The idea behind the article came to my mind when I was working with one of the users. The next bit of magic is using ccivmkfstools/cci.

In today's we will look at how to list VMs with RDM using PowerCLI.
