Cant Upgrade Centos 4.6 to Centos 5.3 with I2O subsystem

crackyblue · 10-08-2009, 05:31 AM

Hi,

I have a supermicro server with I2O running on an old Centos 4.6. I burnt a copy of Centos 5.2 on DVD and tried to upgrade the OS. But strange it didnt saw my harddrives and didnt even prompt to load a new driver of I2O, is there any way around? Strange but 4.6 seems to do this routine.

Thanks and more power

well seeing as it is NOT POSSIBLE to upgrade between MAJOR releases .
this is VERY well covered in the cent docs . VERY WELL COVERED .

do a fresh install.

Hi John,

You will have the same problem with a fresh install.

Try to type "linux noprobe" in the prompt at the beginning of the installation. The installer will ask you which device you need. At this moment, select "I2O Block Device" or something like that.

This is happening because this device driver is no longer loaded by default...
