Which device file I should take for RDM creation

Hi,

I build up a iSCSI connection with a storage device. It is assigned by 5GB volume. Now, I am going to create a RDM disk for a VM from CLI, whatever virtual or physical. Now the following is my command.

vmkfstools -r /volume/devices/disks/

Now, I am confused under "disks" subfolder, since there are 2 similar files but I didn't know which file is the device target file.

naa.6000eb3e31ada42f000000000000000c

naa.6000eb3e31ada42f000000000000000c:1

After experiments, it seems the file without ":1" can be created for RDM because of no errors during creation.

if the first one is device file, what about the second one file(with ":1")? what's the purpose of this file? is that the partition of that volume? But I didn't do any partition operation on the volume.

How can I tell the real device files if there are many similar files ":1, :2, .... , :x"?

thanks for piece of advice.

:1 is this device partition 1;
