v The PCI buses number devices in the following order:
v The controller for the internal media bays is configured before the controller for
v The left removable-media bay is assigned SCSI ID 0, and the right
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 fsx:\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\sdxy 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:
– SCSI ID on the SCSI bus
– Partition on the hard disk drive
