PC hardware doesn't provide an interface to determine what the BIOS thinks the boot device is. If you go into the advanced boot loader options screen, anaconda allows the user to change the drive ordering from our usually correct heuristic. |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 4.0; T312461; Q312461) Description of problem: For our Proliant Dl380 G3 system we have two hard disks. The internal smart array (cciss) and an external SAN disk (sda) interfaced with a Qlogic qla2300. We boot from the internal (cciss) disk. The BIOS of the qla2300 is disabled, because we do not boot from this disk. During the Fedora installation (and later during system startup as well) the qla2300 driver is loaded before the cciss driver. After the installation, when we tried to boot the new system, grub gave a message that it could not find the disk and it mentioned hd1. By changing this into hd0, we were able to boot the system. We also replaced everywhere in the grub configuration file hd1 with hd0. After that we could boot the system without manual intervention. Our theory is that, because the qla2300 driver is loaded before the cciss driver during the installation qla2300 is mapped to hd0 and cciss is mapped to hd1. During the early boot process, the SAN disk is not available, because the qla2300 bios is not enabled, so there is no hd1 at that moment. So, the mapping to hd0 and hd1 should not only depend on the order in which the drivers are loaded, but also on the availability of the disks via the bios. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Make sure both disks are available to the system and that the bios of the qla2300 is not enabled. 2. Run the installation and install the system on the cciss disk. 3. Try to boot the system. Actual Results: We see a boot failure, with a message that hd1 is not a valid disk. Expected Results: Display of the boot splash screen choser. Additional info:
