There are four engineers traveling in a car; a mechanical engineer, a chemical engineer, an electrical engineer and a computer engineer. The car breaks down. “Sounds to me as if the pistons have seized. We’ll have to strip down the engine before we can get the car working again”, says the mechanical engineer. “Well”, says the chemical engineer, “it sounded to me as if the fuel might be contaminated. I think we should clear out the fuel system.” “I thought it might be an grounding problem”, says the electrical engineer, “or maybe a faulty plug lead.” They all turn to the computer engineer who has said nothing and say: “Well, what do you think?” “Ummm – perhaps if we all get out of the car and get back in again?
Customized Dell ESXi 5.0 image makes the 5.1 upgrade fail
When attempting to migrate a few hosts from ESXi 5.0 to 5.1 the update manager continuously failed. After a whole lot of searching and log combing I came across a Dell forum thread that shed some light on to the problem.
Unfortunately, Dell’s updated ESXi image still failed. At this point I thought I would need to take a trip over to the data center and use a USB drive to upgrade the hosts. As I read through the thread, I came across a solution by Harri T (page 5, second to last post).
In essence, use VMWare’s depot to patch the 5.0 install via SSH.
- Download VMware-ESXi-5.1.0-799733-depot.zip and copy it to a local datastore.
- Download tg3-3.124c.v50.1-841079.zip and extract tg3-3.124c.v50.1-offline_bundle-841079.zip to a local datastore. I’m not sure if this is needed because depot.zip above has tg3 already.
- Enter Maintenance mode.
- Enable SSH, log in and type:
esxcli software profile install -d /vmfs/volumes/DATASTORE_NAME/VMware-ESXi-5.1.0-799733-depot.zip -p ESXi-5.1.0-799733-standard --ok-to-remove
- After rebooting exit Maintenance mode and disable SSH.
Pro-tip: Don’t let your HP-UX /optim volume fill up. Your Blackboard Transaction System will go ape shit and then die.
Also, 146 GB isn’t enough. Kind of like the 24 hours in a day.
Wrote my first COBOL application last night:
[deploy@cobl COBOL]$ cat hello.cob
* Sample COBOL program
DISPLAY “Hello World!”.
[deploy@cobl COBOL]$ ./hello
I would bet my financial future that COBOL handles more financial transactions than any other programming language ever created. Too bad it’s a language that won’t see too much of the future.
I work with people just like this.
