How does a blade know to boot from a specific lun? Can you do a LUN-SAN mapping that would make a lun available to only one specific blade each under the correct name?

Is there anyone out there who might have a custom anaconda version which could see at least 32 LUNS or more? I have yet to find a way of installing blades onto 32 volumes which are on a fibre channel storage device. I must find a solution and was now told that I might be able to modify anaconda. Not knowing how to do this, I wonder if someone might already have a modified version? Mike This was my old message, things I've done/tried which have not worked. // 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? // -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
