You can see 2 files ( diskname-rdmp.vmdk & diskname.vmdk) rdm.vmdk is for virtual compatibility RDM and rdmp.vmdk is for Physical compatibility RDM disk. You can validate the RDM mapping files are created using “ls” command in the specified directory. You can use something like VMname-LunID.vmdk. TIP: You can specify the disk name of RDM mapping file in a meaningful way so that it will be easily identified during the maintenance of the LUN’s or disk. CD towards the specific folder where you want to keep the RDM mapping file and execute the below command vmkfstools -z /vmfs/devices/disks/naa.XXXXXXXXXXXXXXXXXXXXXXXXX diskname.vmdk To Create Physical Compatibility RDM, you need to know the NAA ID of the physical LUN which we are going to add it as RDM disk to the virtual machine. This simplifies the operation and troubleshooting. You can create a specific folder to create the RDM mapping file. This will be extremely useful when you have multiple virtual machines sharing the same RDM disks. The only advantage of this method is you can create the physical compatibility RDM mapping file inside any specific folder of the datastore. Create Physical Compatibility RDM Disk using vmkfstoolsĬreating RDM disk Physical compatibility mode using vmkfstools also performs the same operation as what we do it in the Web client. First one is via vmkfstools command (CLI) and the second one is via vSphere Web Client 1. There are 2 simple ways to create Physical compatibility RDM disks. 2 Ways to Create VMware RDM Disks in Physical Compatibility Mode In this article, We are going to looking at the detailed procedure to create VMware RDM disk in Physical Compatibility Mode (RDM Physical). I have already explained the step by step procedure to create virtual compatibility RDM disks. With the VMware RDM in physical compatibility mode, all the physical characteristics of underlying hardware will be exposed. Physical compatibility mode allows direct access of the SCSI device for those applications that need lower level control. We have explained the detailed 11 differences between RDM physical vs virtual Compatibility Mode. As we discussed in the earlier post, There are two types of RDM Disks ( Virtual Compatibility RDM and Physical Compatibility RDM).
VMware RDM ( Raw device mapping) is a mapping file that provides direct access to a LUN on an iscsi or fibre channel storage system for a virtual machine.
