Hello Toasters,

 

I found a ton of information regarding fixing misalignment issues in virtual environments.    However, I am interested in how to resolve misalignment on a physical machine.   The only way I am aware of is to create a new LUN and perform a host based copy of the data to the new LUN.   Is this my only option or are there any other methods that require less overhead/downtime?

 

Here is the situation:

 

Server OS = Windows 2008 Server

LUN Type = Windows 2008

Partition Type = MBR (W2K3)

 

How did we get a W2K3 MBR partition out of a Windows 2008 server?   We didnt.  The LUN was originally created by a W2K3 machine while using an EMC storage array.   The W2K3 server was eventually retired and the LUN was presented to the W2K8 machine.     

 

The LUN was then migrated to a NetApp array using a block for block mirror of the data from the EMC LUN to the NetApp LUN.    Unfortunately, the NetApp LUN was created as a windows_2008 lun type because it was going to be used by a Windows 2008 server - this is where the mistake was made.    So now, we have a Windows Server 2008 box with a disk using a 2003-MBR partition type on windows_2008 lun type.

Again, I'd like to fix the misalignment issue in the easiest way possible.  Creating a new lun and performing a host based copy of the data is doable but requires a fair amount of overhead.   Just wondering if there is a more efficient way to resolve lun alignment issues with physical machines.

 

Thanks!
