Indeed....

Add a "workingDir = " to the VM vmx file.

The vmdk pointer file is only a few Kb so you don't need much space per RDM.

If you wish to use Snapshots (RDM needs to be in Virtual mode), then you have to calculate with space for this also as the delta file(s) will be placed in the homedir with pointerfile (per default)

Hi Rubeck,

Thanks for your prompt reply.

In case I need to snapshot the RDM volumes in the future, is there a way to place the delta files on to a different LUN and not on the proxy LUN?

Rgds,

Hello,

Yes, you can do this multiple ways. One is to redirect all snapshots to the same lun via the VIC. or change the 'working directory' for the specific VM.

Note that you do not need to use a proxy LUN, when you create the VM the RDM is pointed to within that VMFS' metadata. In general all VM files are stored together.
