From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050923 CentOS/1.0.7-1.4.1.centos4 Firefox/1.0.7 Description of problem: A HP Proliant DL380 G3 server was installed with RHEL4 AS Update 2 (was previously running RHEL3 without any problems). Boot disk is on Smart Array 5i RAID controller (cciss driver), two 36 GB disks mirrored RAID 1+0. Disk partitions: /boot (100MB), / (about 30GB), swap (4095MB). Installed RHEL4U2 with "Minimal" set of RPMs as a test. After installation the server should boot for the first time. When it comes to the boot stage, messages from Grub are expected, but in stead the screen goes black and nothing happens for hours. The mirrored boot disks show continual activity, but nothing happens. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install RHEL4 AS Update 2. 2. First reboot after installation: Machine hangs. Actual Results: Server hangs in booting forever with a blank screen at the Grub stage. Expected Results: A normal boot. Additional info: Additional disks added since the upgrade from RHEL3: 2 logical volumes added on cciss controller, and external RAID box on PCI SCSI-controller with two disk volumes of 996 GB and 1004 GB. I looked at Bugid #152954 and tried adding acpi=off after the initrd line in grub.conf, but the server still hangs in the same way.
I removed the external RAID box on PCI SCSI-controller with two disk volumes on SCSI ID 0, LUNs 0 and 1. I then reinstalled RHEL from scratch, and now everything worked as expected. I conclude that RHEL4 installation can't handle SCSI disk devices with multiple LUNs. I reconnected the external RAID box to the running RHEL4 system, but only the disk device on LUN 0 is visible as /dev/sda, whereas the device on LUN 1 can't be found. So RHEL4 really seems to have problems with multi-LUN disks (?)
