Failed to extend disk : One of the parameters supplied is invalid (1).

What am I missing?

Looks like it did not understand 2048M. I had entered 20G and it took it.

2048MB = 2.048 GB

If you wanted it to be 20GB, need to add another 0 in there. If you do it by GB it makes the math a little bit easier

it also may be easier to do it from the volume in which the .vmdk is, that way the command line is shorter.

cd vmfs/volumes/DS4200_LUN_01/Web

vmkfstools -X 20G Web_1.vmdk

Then you can use a helper VM if its a Windows box, as seen here.

Kyle,

typing 20 GBextended to 20 GB which is being seen correctly in Computer Managements

all works OK and yes I have CD to the actual location.

the question I guess is why it is not taking in M or MB?

[khughes]

When you do the command - vmkfstools -X 20G Web_1.vmdk

You're not extending it 20GB, you're telling it you want "Web_1.vmdk" to be 20GB in size. So the total size is going to be 20GB (not 10GB+20GB). In your case of doing the M, unless the vmdk file was only 1-2GB in size, it can't shrink the .vmdk file down to a 2GB file, it can only increase. My assumption is if you did vmkfstools -X 20000M Web_1.vmdk it would work
