With the release of RHEL5, I downloaded the media from RHN and tried again. The BIOS options for this Asus P5B motherboard is to use AHCI. Disk 3 and 4 is not recognized by RHEL5 during the installation of the OS. A work around is to change the Asus BIOS (Version 1102) option to utilise IDE as oppose to AHCI. During the installation of RHEL5, all 4 disks are detected as sda,sdb,sdc and sdd. This should not be a problem in the current release, please re-open if necessary. |
Description of problem: How reproducible: Always. Steps to Reproduce: 1. Hardware: Asus P5B motherboard, enable AHCI on Intel ICH8 SATA controller. enable IDE on JMicron SATA Controller. 4x SATA II hard disks connected to the Intel ICH8 SATA ports. Nothing connected to the JMicron SATA ports. Intel Core 2 Duo E6300 CPU. 1x Intel Pro/1000 PT desktop controller installed on the last x1 PCI-Express slot. 1x Asus Nvidia 7100GS video card installed on the first PCI-Express slot. 2. Install RHEL5 Beta II 3. During disk partitioning in disk druid, you won't see SATA disk 3 and SATA disk 4. You will see only the first two disks. Partition with md0 and md1, RAID 1 devices across the first disk. But /boot into md0 as a EXT3 filesystem. Create a Logical Volume Group in md1 and put / and swap there for the purpose of testing. 4. After installation and rebooting you'll see an unrelated bug with the video display going out of range and not showing anything on the screen. Fix going into single user mode and editing /etc/X11/xorg.conf, adding in the Scree section: SubSection "Display" Depth 24 Modes "1024x768" EndSubSection Then at the shell, init 5 to go into multi user mode and setup the OS for the first time. 5. After logging in, check that /dev/sdc and /dev/sdd does not exist. Check that /dev/sda and /dev/sdb exists. 6. lspci shows that the AHCI ports are detected. Actual results: Only the first two SATA II disks detected. Expected results: All 4 SATA II disks detected. Additional info: Note that the SATA port numbers, logically, appear out of synch. i.e 1, 3, 4, 5 rather than 1,2,3,4. Intel ICH8R appears to be reported in lspci rather than ICH8. UDEV appears to hang the first time after starting up RHEL5Beta. Difficult to reproduce.
