Hello everybody. I'm working on a thing I never tried before. I did some googling but I don't think I haven't found any thing correlated to this. The situation is pretty simple: I'm configuring a FreeBSD (6.1) server = to boot from a SAN thru a QLogic 2340 Fiber Channel card. This in general = is not a problem as I already have another working machine with this solut= ion. Now for a couple of reason not related to FreeBSD this new machine won'= t yet _ boot _ from the SAN itself but at the same time have all the syst= em installed on the SAN. What I need to do is have a (local) boot device t= hat loads the bootsector, the kernel and then starts everything else from t= he disk in SAN. I thought about accomplishing this with a BOOT-CD that starts up the ke= rnel and then from the fstab loads the /, /etc, /usr and so on from the SAN.= Now my question is this: how do the kernel know where to search the fst= ab (considered that the fstab says where to find the /etc)? I mean: I supp= ose I have to put on the CDROM an exact /etc/fstab for that installation?? = Or this could be avoided? Also because I may need to edit the fstab for th= e machine without having to reburn the CD? so what? Or maybe the kernel c= an actually just be read from the CD and then everything else from the ( S= AN | local ) drive? Am I missing something? I'm yet in the make buildworld buildkernel stage so maybe when making t= he make distribution to create the ISO everything will appear clearer to m= e but right now something it's not really clear. I hope the scenario is clear. Any suggestion? Any link to any kind of documentation? Thank you very much. Andrea Brancatelli=
