hi, we've got a server with a 8 port 3ware card and 2 ide system disks. now we'd like to replace the ide disks with scsi disks or sata disks (these also recognized as scsi in the kernel). but we can't boot from it. the problem are twofold. first in the normal case the first scsi host scsi0 id the 3ware card, but grub only see the first 8 disk so if the system disk are sdi and sdj the one can't boot from it. on the other hand if one disk is removed from the 3ware card or the kernel reorder the scsi disk and sdi become sdh which is also a problem both for the bios and for the kernel. if i change the order in bios, the kernel still use as 3ware scsi0. if i use scsihosts kernel param or load the scsi driver (through modprobe.conf) in a reverse order then the kernel hang forever during the initialization of the 3ware driver. any tip? thanks in advance. yours.
