Extending Dynamic Disk

Posted on 2009-04-30

I have a Windows 2003 with a Disk0 (Basic) [Volume (C:)] ,
and a Disk1 (Dynamic) coming from a SAN, with Volume (X:), say 100GB.
Who implemented this server, decided to create such disk as Dynamic.

Now I am going to expand (SAN side) the LUN, and my Disk1 will be, say 150GB.

I have simulated in laboratory the situation, in a Virtual Machine,
using both DISKPART and Disk Management-Extend Volume,
extending original Volume from 100 to 150 MB.
What comes out is the creation of another partition in the same Disk1,
of 50 MB, always named X:, so that X: volume will be 150MB.
But I see 2 partitions in the same disk,  same Volume (X:).

The  picture reports phases from a laboratory Virtual Machine.

Question: is there a way to extend original Partition/Volume from 100 to 150 GB
as I do by Diskpart/Extend in Basic Disks ?

(As shown in last frame of picture, simulated deleting and re-creating Test volume )

    Doesnt it treate both as drive X: as you wanted it?

    You would be able to resize the partition by backing up the data, recreating the partition and restoring the data but even easier, there are utilities that can resize the partition with the data still there. Im sure there are free solutions out there but partition magic has always been my favorite as a paid solution
