I have RX8640 where the Win 2003 Datacenter is installed on the Npartition 2. I convert the basic boot disk of Win2203Datacenter to Dynamic disk to can mirror the boot disk and the system asked me to restart twice. on the second restart it give me an error that i must restore the NVRAM and the file ia64ldr.efi it come hiden into fs0:> file system. The system now is down.
Can any one help me? Any idea?

check this link directly form Microsoft :
To create or break a mirrored boot volume (Itanium-based computers only)

this issue occurs because somehow the pointer to the boot partition has not updated with the correct partitionnumber, this is part of the procedure to setup mirroring on IA64 as described in this article from Microsoft:
You have to understand that when converting to dynamic disk, that the partitionnumbering changes because some small LDM partition is inserted in between the existing partitions, so the pointer to where the bootloader is located is not up to date and the next boot will indeed fail.
So the boot file located in fs0:\efi\Microsoft\Winnt50\ needs to be edited manually now with the correct partitionnumber to fix this again.
There is no need to reinstall the operating system or restore the nvram file, each time you do this kind of boot disk conversion, this same will happen if you not follow the steps in this article very very carefully.
The ia64ldr.efi file is always a hidden file.
Log a call with HP support and they will fix this for you.

I did the same procedure that describde in the microsoft site but using Windows and not the command prompt.
CAN BE THE REASON? i will reinstall the windows 2003 DataCenter and then trying using the commande prompt and let you know.
I think when we convert from Basic to Dynamic on integrity system, they have some changes happen with the disk numbering and the boot partition number it will changed.
We can check up this thread waiting the installation? How we can retore the boot partition Number from EFI Shell?
