Kernel: Version 2.2.18
Symptom:
During the installation process of SuSE linux on a Dell Poweredge 6450 ( with a SCSI-RAID System PowerEdge Expandable RAID Controller 2 Dual Channel PERC2/DC),
your harddisks can't be accessed properly.
Cause:
This controller uses an I2O emulation. Some unixderivatives as older unixversions can't access these devices. This misbehavior
depends on the kernel version. I20 is an architecture which was developed in order to reduce I/O conflicts. These types of controllers
include hardware components to support those functionalities outside of the regular kernel processes. I2O is also referred to as
an intelligent I/0 interface which is specially designed in order to collaborate with the PCI bus. The PERC2/DC controller
uses the I20 emulation as default.
Solution:
Please deactivate the I2O emulation in the bios of your controller.
Procedure:
-
Please switch your computer on and press the keys < Control > + < M > (the PERC2/DC bios will
will apear).
-
Please choose 'Objects' and then 'Adapter' from the menue.
-
Change the 'EMULATION MODE' from 'I20' to 'MASS STORAGE'.
-
Press < ESC > two times in order to save these changes.
