Hi,

after successfully testing iscsi boot of a xp client pc using iscsitgtd I 
decided to try to use COMSTAR as iscsi target software since everybody seems to 
agree that it is the future and has far better speed.

Now, after spending this afternoon checking and redoing the basic steps to 
export a zvol as a lun through comstar just to see the xp client (booting 
through gPXE) fail to boot I started looking around for some clue till I found 
out this bug id: 6701531

It says that sbd (which I think is the sbdadm program) writes LU metadata on 
the first 64KB of the backing store (my zvol in this case).

So, I do a dd of the xp hard disk to a zvol but as soon as I issue the sbdadm 
create-lu command it destroys the first 64KB of that disk image making boot 
impossibile (in fact, gPXE stops saying it can not boot from the disk).

Now, please, tell me this is not true .) How can copy a disk image to a zvol 
preserving the image integrity? How can I create a LU from a zvol which already 
has data inside (think about moving iscsitgtd exported zvols to comstar)?

Maurilio.
