\"moveexistingrdm01\"<\/p>\n

Moving an existing RDM from one virtual machine to another some steps are required to avoid\u00a0data loss and to keep\u00a0the disk configuration.<\/p>\n

The RDM allows a virtual machine to directly access and use the storage device and before proceeding with the move, the\u00a0virtual machine where the RDM is currently attached must be\u00a0shut down.<\/p>\n

From vSphere Web Client (vSphere 5.5 has been used in the example), right click the\u00a0VM to process and select Shutdown Guest OS<\/strong> option.<\/p>\n

\"moveexistingrdm02\"<\/p>\n

Click Yes<\/strong> to confirm the shut down.<\/p>\n

\"moveexistingrdm03\"<\/p>\n

 <\/p>\n

Remove the RDM<\/h2>\n

From vSphere Web Client, select the VM and click Edit Settings<\/strong> in the VM Hardware<\/strong> area.<\/p>\n

Keep in mind this procedure\u00a0destroys the mapping file<\/strong>, not the LUN content.<\/p>\n

\"moveexistingrdm04\"<\/p>\n

Identify the RDM hard disk<\/strong> to\u00a0remove.<\/p>\n

\"moveexistingrdm05\"<\/p>\n

Click on the 'x' sign<\/strong> to remove the disk.<\/p>\n

\"moveexistingrdm06\"<\/p>\n

Enable\u00a0Delete files from datastore<\/strong>\u00a0option then click\u00a0OK<\/strong>.<\/p>\n

\"moveexistingrdm07\"<\/p>\n

Hard disk 2 has been removed from the VM.\u00a0LUN and its contenut<\/strong>\u00a0are not altered during this step.<\/p>\n

\"moveexistingrdm08\"<\/p>\n

 <\/p>\n

Attach the RDM to the new VM<\/h2>\n

In the new virtual machine, click Edit Settings<\/strong>\u00a0under the VM Hardware<\/strong> area.<\/p>\n

\"moveexistingrdm09\"<\/p>\n

In the\u00a0New device<\/strong>\u00a0field, click the right arrow to open the\u00a0drop-down menu and select RDM Disk<\/strong> option.<\/p>\n

\"moveexistingrdm10\"<\/p>\n

Click Add<\/strong> button.<\/p>\n

\"moveexistingrdm11\"<\/p>\n

From the list of SAN disks or LUNs, select the\u00a0LUN to access directly and click OK<\/strong>.<\/p>\n

\"moveexistingrdm12\"<\/p>\n

Click on the just attached New Hard disk<\/strong> and select the appropriate\u00a0Compatibility Mode<\/strong> (i.e. Physical<\/em>).<\/p>\n

\"moveexistingrdm13\"<\/p>\n

Click OK<\/strong> to save the configuration.<\/p>\n

\"moveexistingrdm14\"<\/p>\n

The new RDM disk (Hard disk 2) is now attached to the VM.<\/p>\n

\"moveexistingrdm15\"<\/p>\n

Access the processed virtual machine (a Windows VM in the example) and open the Disk Management<\/strong> tool. Right click the new attached disk and select Online<\/strong> option.<\/p>\n

\"moveexistingrdm16\"<\/p>\n

The partition previously configured in the old VM is retained and is now available to\u00a0the new VM.<\/p>\n

\"moveexistingrdm17\"<\/p>\n

To check if\u00a0the RDM move procedure have been completed successfully, try accessing files and folders using\u00a0Windows Explorer<\/strong>.<\/p>\n

\"moveexistingrdm18\"<\/p>\n

As best practice, before moving disks and LUNs be sure to have a full working backup<\/strong>.<\/p>\n
