I agree, I'm not a fan of running it on Windows either but I was saying that you do have other options if you're not comfortable using Perl.
I finally got access back to our development server (had small outage due to very old UPS) ... anywho, take a look at this script:
The script allows you to create and add a new RDM and remove and delete RDM. Please take a look at the examples provided and would recommend taking a look at how the script works so you understand what's going on.

There's a few errors with VMware's vdiskcreate.pl and their VMUtil.pl module which must have been using some old code ....
The reason you're receiveing the invalid backing, is it's basically selecting the first available LUN that it can find on your system which may or may not be correct. It's also hard coding the compatibility mode of your RDM ... but not only that, they're using the wrong key word.
Here is the snippet of code that needs off:
/usr/lib/vmware-vcli/apps/AppUtil/VMUtil.pm
my $lunId = $host_storage_system->storageDevice->scsiLun->[0]->uuid; my $deviceName = $host_storage_system->storageDevice->scsiLun->[0]->deviceName; $disk_backing_info = VirtualDiskRawDiskMappingVer1BackingInfo->new(compatibilityMode => "physical",
So basically, what should have happened is go through all the scsiLun[] and figure out the proper device to use, once you've narrowed that down, you'll go ahead and assign the UUID and DEVICENAME.
For the compatibilityMode the keyword should be either physicalMode or virtualMode
Here's the following changes I made to the script and actually extracted and redefined get_vdisk_spec() and put into the executing script:
my $LUNS = $host_storage_system->storageDevice->scsiLun;
my ($lunId,$deviceName);
foreach(@$LUNS) {
if($_->lunType eq 'disk') {
my $lunCap = (($_->capacity->blockSize * $_->capacity->block)/1024);
if($lunCap eq $size) {
$lunId = $_->uuid;
$deviceName = $_->deviceName;
}
}
}
$disk_backing_info = VirtualDiskRawDiskMappingVer1BackingInfo->new(compatibilityMode => "physicalMode",
deviceName => $deviceName,
lunUuid => $lunId,
fileName => $fileName);
The current logic is relying on the fact that you pass in the correct size of the RDM (MB) and make sure it's the exact since it will be converted into (kb) and compared with the devices that are available. I also just hard code the mode, but you can create either a physical or virtual RDM by just modifying compatibilityMode
I'm not sure where you got rdmCreate.pl but it's definitely not written to correctly handle RDMs and neither is vdiskcreate nor the VMUtils.pm module. If I have some time, I'll see if I can write up something that's slightly easier to use.
Here is a sample execution with the exact syntax using these modfications:
The input to the script is pretty simple, you just need to specify the backingtype which is rdm, the exact disksize and in my case I have 1.95gb which turns out to be 2000mb and I want the filename to be rdmVM_1.vmdk (this can be anything) and then I specify the name of the VM
[vi-admin@scofield vm][http://esx40-1.primp-industries.com|http://esx40-1.primp-industries.com]$ ./rdm.pl --server esx40-1.primp-industries.com --backingtype rdm --disksize 2000 --filename rdmVM_1.vmdk --vmname rdmVM Adding Virtual Disk on Virtual machine rdmVM in the host esx40-1.primp-industries.com with file name rdmVM_1.vmdk calling the reconfigure VM returned from reconfigure VM Virtual Disk created.
Note: This was executed on vMA 4.0 directly against the ESX 4 host that has the VM

Please re-read my last repose, the answers are provided there. You have not made any of the modifications I spoke of ... that is why it's failing, your version of rdmCreate.pl which is really just a mod of vdiskcreate.pl is not written properly to handle RDMs and it uses the VMUtil.pl which also has errors in the script. Unfortunately I don't have access to my development system to provide a cleaner script but what you're looking for is in the previous post.

Until I have access into my development environment, I won't be able to share my version of the script.
rdm.pl is just the name I gave my script, you have to understand that the script you have is not written correctly to handle RDMs nor is the VMUtil.pm that it references. It's also good to understand what is going on in the script ... remember this can also be done using PowerCLI or other languages to the vSphere SDK, though I'm a big fan of the Perl implementation but it does require some knowledge of Perl and understanding of the vSphere API
I'll provide an update when I have access back into my environment.
