Dear Greg, Thank you very much for thte suggestions.

I have tried both pci=bfsort, pci=nobfsort and pci=nosort both on the install side (in /tftpboot/...) and by modifying grub.conf on the localboot side (on a client). Unfortunately, it doesnt seem to do any difference in the existing ordering. > I've personally had SAN devices show up as sda before, which led me > to > remove all unnecessary modules from the SystemImager boot kernel. > Sometimes those virtual devices are virtually attached via USB.

Really, I should think that I would _need_ that support (on install time) in order to make the virtual device be detected and configured as sda, rather than _not_ having support. Also, the only keyboard available on the nodes is a virtual one on the USB-line, also connected through the iLO interface. In the present case, it seems that the virtual CD _is_ detected on install time, but it happens late, so sg0=sda is already assigned to the HDD. > You could also alter your master script to > detect if the virtual drive is sda and automatically format sdb > instead, > but eliminating unnecessary devices is probably the better solution. I am now trying this solution. As all the nodes are really identical, I can hardcode the change rather than detecting it. But it feels like a clumsy hack. Obviously, I must be careful not to make disk edits to the image, as the disk should be sdb when the node boots (but sda while it installs). And there is a small matter of getting grub (systemconfigurator) to do the right thing as well... > -Greg ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
