I'm looking to clone a disk attached to an HP server that has a smart board

wanted to know if any tool like the ghost, but I can do scsi disk images from disks connected to a scsi card like a hp smart .

Perhaps you could start the server with DOS , load the hp smart  driver and then after that make the ghost image.

Do not know if there is any software that allows me to do that

Do you want to image the entire disk, or just the usable blocks that are exposed to the O/S?  Reason I ask is the controller uses metadata, so physical block X is actually stored at block X +Y, where Y is the number of blocks in metadata. The only way to get to the entire disk is to put the card behind a NON-RAID controller.

(You can image behind a non-raid controller using standard linux and a non-raid controller with the native dd program).

What are you trying to accomplish is the real question, because if you did perform a binary image clone, then it certainly won't work if you just slap it into another system and expect to see your data.

Then you want to clone the logical drive, not the physical drive.  Is this a single disk that is visible  to the O/S, or something like a RAID5 logical device?  What controller, exactly do you have?  This is important as not all cloning software supports all controllers.

You need to determine make/model of the controller.  Ghost (a painless and excellent product) doesn't work with just everything.  Remember, testing backup is easy and nobody ever loses data when they backup. It is the RESTORE test that you need to perform.  If you shortcut by not going to the effort and confirming exactly what you have, then you could very well be wasting your time backing up in the first place.  

I do not know if you will be able to see the partition from DOS, it depends on the controller. Even if you have to shut down to boot and go to the BIOS, you must get the controller model.  support.hp.com  has software that runs under versions of windows that you should have installed anyway to look at controller health and configuration.  I suggest you download their software anyway.
