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.

Capacity Planner Installation Gotcha

If you are a VMware Partner and use the Capacity Planner tool, be warned that the official installation instructions are … well, they are just wrong.

After downloading the Capacity Planner Collector package on a correctly configured platform as an account with Local Admin privileges, you can’t just “double click” on the install file (as the instructions would have you believe).  You have to right click and “Run As Administrator” (Windows 7 or Vista) or “Run As…” (previous desktop platforms) and explicitly choose a user with Local Admin privileges.  It might seem like it would be good enough to be logged in as the user with privileges, but it’s best practice (and actually mandatory) to explicitly elevate the privilege of the installation application.
When we interact with other people, our auras merge, and we began to exchange vardenafil online australia energy (information). This can include physical symptoms such as diabetes, depression, hormonal imbalance, tadalafil vs cialis excessive alcohol consumption, drug abuse, fatigue, and traumatic sexual past. If you are opting for this particular videoleadspro.com generic cialis online medicine make sure you follow the prescription provided to you along with the medicine.

You can tell this is a problem if, after you install the Collector, you run it and get multiple errors window popups that can eventually be cleared.  In addition, a project setup will be able to add jobs to the queue, but they’ll be in a “waiting to run” state with nothing seeming to block them.  When I saw this problem, the service was even installed and running…
A un-install/re-install cycle (run as administrator) fixed both the symptoms.
