Any ideas what I can do to get this updated?
I ran into this problem before too. You have to update the system BIOS and all other firmware first. Then, update the CERC controller firmware. Dell was very generous in helping me troubleshoot this issue and we were on the phone for several hours until we finally updated the system BIOS and BMC firmware and other things that the firmware update for the controller took. The symptoms were just as you described... the update program would say it completed successfully, but upon reboot it was still the same old version. > > 2) Is there any drive size limitation on the CERC that might prohibit > us from using Seagate Barracuda 1.5TB drives? Yes, I think there are limitations with the CERC 1.5/6ch controller. That controller is really poor anyway. I recommend that you get a PERC 5/I card and use that instead for your hard drives. We have a PE1800 with a PERC 5/I and it works great with 3.5TB of RAID5 that can do 500MBytes/sec sequential I/O; it is a huge improvement for the PE1800. > > Thanks! > Howard > -- > > Never interrupt your enemy when he is making a mistake > Napoleon Bonaparte > > Howard Powell > Computer Support Technician > Astronomy Department, UVa _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
