Change disk controller type into a linux distribution box

[nicolas_ruiz]

Hi all,

I would like to change the disk controller type from LSI Logic to Buslogic under my debian Etch box.

I think that my read-only files problem with it come from the driver.

But, how can i configure my Debian to restart with a new disk controller without panic ?

Thanks a lot for giving to me a way to search.

Hello,

Make sure there is first a buslogic SCSI driver in your Debian installation. It is not always there. Then make sure it is part of the initrd.

This is really a Linux OS issue.

Best regards,

Edward

Hello Edward,

I've saw an interresting secondary trick to my disk controller driver problems : http://www.tuxyturvy.com/blog/index.php?/archives/31-VMware-ESX-and-ext3-journal-aborts.html

To resume, the autor said that original LSI-Logic have a bug into the file "mptscsi.c". So, just change a line of response to a SCSI BUSY trigger.

On my linux box :

srv-groupware:~# dmesg | grep MPT

Fusion MPT base driver 3.04.01

Fusion MPT SPI Host driver 3.04.01

srv-groupware:~#

So, two solution, change ESX disk controller type to buslogic (as i heard this type is less efficienty than LSI) or modify the actual LSI driver and recompile kernel with it.

What do you think about this ?

There's a KB entry (including a solution) regarding the lsilogic problem.
