I have tried to get round this by building a ramdisk with the required utilities on it but the firmware upgrade still fails. The systems are currently Fedora 9 based. Has anybody managed to do this sort of upgrade using these utilities and if so HOW?

Mikkel </pre> </blockquote> I had thought of this and am trying to construct a suitable initrd image to try this out - the machine has no local mountable devices other than its hard discs. The root discs are on the internal controller and the PV units are on an additional Perc 4/DC controller. The Dell utility is (I think) taking the root discs out when scanning the scsi environment. Given the hardware I will have to do a network boot (PXE) and try to run rescue from there, which means getting the Dell utilities into the rescue image. I was hoping that somebody on the list had done some very similar and could tell me that this is going to work, I have the horrible feeling that I am going to end up with this failing to work because the Fedora environment is not enough like the Redhat Enterprise 3 environment the tools were developed for. I will keep you apprised of any progress (or lack of) Howard. </body> </html>
