– SCSI ID on the SCSI bus
– Partition on the hard disk drive
v The PCI buses number devices in the following order:
1. Node 1 internal devices
2. Node 1 PCI slots
3. Node 1 RXE-100 PCI slots, if configured
4. Node 2 internal devices
5. Node 2 PCI slots
6. Node 2 RXE-100 PCI slots, if configured
7. Node 3 internal devices
8. Node 3 PCI slots
9. Node 3 RXE-100 PCI slots, if configured
10. Node 4 internal devices
11. Node 4 PCI slots
12. Node 4 RXE-100 PCI slots, if configured
v The controller for the internal media bays is configured before the controller for
the external media bays.
v The left removable-media bay is assigned SCSI ID 0, and the right
removable-media bay is assigned SCSI ID 1. You define the SCSI IDs that are
assigned to devices attached to the external controller or to PCI adapters.
Solution: Update the root partition in the elilo.conf file after moving or installing
hard disk drives or changing the scalable partition. For example:
Edit fs x :\efi\SuSE\elilo.conf where x is the EFI file system number containing the
Linux loader.
Locate all lines that start with root=\dev and change all occurrences to
root=\dev\sd xy
where x is the drive letter and y is the partition number.
Alternatively, change the lines to
root=xyy
where x is the major device number and
yy is the minor device number.
SLES8 identifies nonexistent DVD/CD-RW drives
Description: When two DVD/CD-RW drives are installed in the xSeries 455 server,
SLES8 assigns a logical unit number (LUN) to multiple nonexistent drives. However,
SLES8 configures only the two installed drives.
Solution: This problem does not occur with the Unitedlinux 1.0 Service Pack 3 for
IPF installed on the operating system. Download and install the service pack, when
it is available.
Workaround: Type the following command:
hdalun=0 hdblun=0
To issue the command on every restart, edit the elilo.conf file and add the boot
option to the stanza for the kernel you are booting. For example:
image=/vmlinuz
label=linux
root=803
initrd=/initrd
append="hda=ide-scsi hdalun=0 hdblun=0"
