I have a linux VM that is using the Busilogic SCSI controllor that ESX 2.5 provides. I want to use the LSI SCSI controller is there a way to do this without re-installing the OS.  

When I changed the scsi controllor from Busilogic to LSI in the virtual center setting  and try to boot I get a kernel panic.

HELP

There are or used to be cautions about the LSI emulation but I don't remember the details.
The kernel has to have the appropriate LSI SCSI module either built-in to the kernel or in the initrd, so you are looking at some kind of kernel rebuild. All the LSI controllers seem to be RAID so you might have to reinstall your filesystem - carefully read the ESX documentation about this.
The kernel is panicking because it can't mount the root device.
Why do you want to change from BusLogic? Unless you have a really good reason, just stay with it.
