We have a number of IBM3850-M1 with QLA2460. All bar one are working fine booting off the SAN adapter apart from one. This broken one has been working and then failed on a reboot. Unfortunately the person who fixed it last time, can't remember what he did to fix it (we think he got lucky ;-)). The server boots fine off its local raid disk with "Rehook INT 19h" disabled in the bios. When we try to bring the SAN back in it seems to go out and try to do a network boot but, then just sits there with blank screen and flashing cursor. Any tips in debugging this issue gratefully received.
