Device /dev/hda3 not found (or ignored by filtering)

I just created a partition (/dev/hda3) with fsdisk and here is how things look:

when i run

vgcreate /dev/hda3 

i get the following error:

Device /dev/hda3 not found (or ignored by filtering).

Now What? After some Googling i found out that you have to run a “partprobe” command.

partprobe /dev/hda

Now i am able to run the

vgcreate /dev/hda3

without a problem.

The partprobe command is used i lieu of rebooting the system. It is a command to let the system know that the partition table has changed.
