More on DL180 G5 Host Updates

Leave a comment

After using a CentOS LiveCD to update an HP DL180 G5 E200 storage controller’s firmware, without being able to recognize the 3TB SAS drives (625031-B21) connected to it, I went back to the well and updated the BIOS to 2010.10.25 (8 Dec 2010) using the same method.  I just re-used the USB stick and added the new update in a new directory.  But no joy on recognizing the drives.  This step was a bit scary as the DL185 G5 has a known issue with needing to go to an intermediate BIOS level.   Skipping that will brick the system.  But nothing like that is anywhere in the BIOS version history for the DL180 G5.  It didn’t get bricked.

By the way, after flashing the BIOS, the system fans ran at their highest RPMs continuously, making it sound like a plane was taking off in the rack.  Updating the BMC/Lights-Out 100 controller to 3.20 (B) (22 Jun 2010) fixed that.  That update wasn’t available from Linux.  It’s packaged as an executable that creates its own bootable USB stick.  After doing that (on yet another stick; how many of these things should I keep around?!), I ran the update, only to find it used FreeDOS as it’s boot environment.

Studies generico cialis on line buying here were conducted in which 500 couples from five different countries and regions participated.

The causes of erectile dysfunction generic for viagra are both physical and psychological. I really wish these things were all available as Linux tools.

This issue of not recognizing a drive that’s specifically mentioned in the E200 QuickSpecs document is pretty frustrating.  If one can’t trust that document, exactly how does one find compatible hard drives?

Firmware Updates on vSphere Hosts

Recently, HP and Dell have both come out with their latest generation hardware platforms (HP’s Gen8 platform and Dell’s 12th generation platform).  Along with those platforms come updates to embedded management features (HP’s iLO and Dell’s iDRAC 7).

Great stuff.  But sometimes in the real world, we’re faced with hardware that wasn’t manufactured this year.  How does one manage those platforms in a virtualized environment?

High blood sugar levels during the early weeks of pregnancy can raise the risk of birth defects, discount cialis you could try here miscarriage, and diabetes complications. Some couples claimed that they had enjoyed multiple orgasms after the use of levitra properien . levitra should be consumed after the prescription. MEDICATION – common drugs for blood pressure, antidepressants, antihistamines, appetite suppressants, tranquilizers, and cheap levitra on line an ulcer drug called cimetidine causes erectile dysfunction as a side effect. However, when a tadalafil cheap prices check these guys person comes under stress or pressure, which may be unsafe for those who take specific medications. The specifics of the problem that I faced are probably not that surprising.  I was adding storage to an HP DL180 G5 and the 3TB drives I was adding weren’t recognized by the controller.  Step one is to make sure that the drive controller firmware up-to-date.  The instructions on the HP website have a great procedure for downloading the Smart Update manager, using an HP utility to create a bootable USB drive with it, and adding the firmware update to a subdirectory.  In a note on the bottom, it indicates that this procedure won’t work for 100-series servers.  Oops.  However, there’s a Linux version.

After futzing around with some thin Live CD distributions, I finally downloaded CentOS‘s most recent, stable LiveCD ISO and created a bootable USB drive using UNetbootin‘s “from ISO” option, and put the firmware update software for Linux in the root directory.  When I booted into CentOS from the USB on the HP server, the USB was automatically mounted in /mnt/drive/sda1.  From a terminal window, I upgraded to root privileges (you don’t log in as root, do you?), and ran the flash utility.   It took less than a minute to run, and a reboot showed successful update of the controller firmware.
The drives are still shown as 0.0GB in capacity, but that’s another story.
Yet another reason why a LiveCD should be a standard part of the toolkit.
