I've tried everything I can find and think of or that has been suggested. I have a Xyratex/MTI type chassis split into 32 volumes. I need to install 32 blades onto each volume so that I can remove the drives on each blade. When I start a Linux install on a blade, it never sees all of the volumes, only LUNS 0/1. I need to see all 32 LUNS so that I can install all of my servers. I've tried all of the following; RHEL4, CentOS4.4, others. I don't really care what the distro is, so long as it runs basic services such as web/php, qmail, etc. What I do need however is that they be GFS/Cluster machines. I've tried passing the information at the installers command line; scsi_mod.max_luns=256 scsi_mod.scsi_dev_flags=INLINE:TF200:0x242 I've tried many variations of these types of commands with no result. I've then set up a PXE boot server thinking that I might be able to pass the options using pxelinux.cfg. Still no luck, it only sees two LUNS. I've tried installing from network with a recompilled initrd.img from a machine which was already installed and modprobe.conf modified to see the LUNS. The donor server can see all of the volumes, the installing version dies with a kernel problem since it cannot see the same already installed volume. What in the world can I do? Is there a guru here who can tell me how I can do this? Thank you VERY much for reading this :). Mike
