fa - hex value of the LUN ID (250 in decimal)Ĩa75393becad4e430004e270 - volume serial number on the FlashArrayĥ.The above string can be analyzed as follows: Once you have the vml identifier we can then find the LUN ID and the volume identifier to match it to a FlashArray volume. Under the disk properties locate the 'Physical LUN' section and note the vml identifier.Ĥ. Locate the desired RDM you wish to inspect and expand the properties of the disk.ģ. Right click on the virtual machine and select 'Edit Settings'.Ģ. There are times where you will need to determine which volume on the FlashArray is associated with a Raw Device Mapping.ġ. Identifying the underlying volume for a Raw Device Mapping While the introduction of RDMs provided several key benefits for end-users those topics are outside of the scope of this document. For an in-depth review of RDMs, and their benefits, it is recommended you review the Raw Device Mapping documentation from VMware. This technology is called a Raw Device Mapping, also known as an RDM. In the early days of ESXi, VMware provided the ability to present a volume / LUN from a backend storage array to a virtual machine directly. Removing a Raw Device Mapping from a virtual machine.
