Hi,

The Adaptec and LSI Logic (formerly AMI) controllers use different technology. It is not possible to change the controller without loss of data.

Thanks for using the Dell Community Forums!

Great, thanks. I'll double check the firmware version. By the way, I think it was you I emailed a couple of weeks ago looking for the dset utility.

Hi Mark,

Thanks for the fast response. I found another 4300 that we could take out of service temporarily and robbed the AMI card out of it. Is there a procedure to bring the machine back up on the new AMI card without losing data?

Hi,

The only risk here is if the 2 controllers were at incompatible firmware revisions. If you keep your systems regularly updated, there should be no concern.

Install the new card into the system, but do not connect the hard drives. Boot the system to the CTRL-M Perc BIOS > Configuration and clear the existing configuration. Power down, connect the hard drives, reboot the system, again to the CTRL-M Perc BIOS > Configuration > View / Add Configuration. You may get a message asking to read from NVRAM or Disk, choose Disk. Make sure the configuration is shown as it was with the old controller, then escape and reboot.

Thanks
Mark
