Updating Java to 1.7 Breaks Dell EqualLogic VSM

I loathe updating Java because you never know what it will break. This morning, it was the Dell EqualLogic VSM plug-in for vCenter.

Upon launching the plug-in, I got these errors:

I thought to disable the current version and enable the previous version, but there is a way to add this URL as an exception.

Launch the Java control panel (I’m running 2008 R2) and click on the security tab.

Click the edit Site List button:

Add the URL in the above mentioned error, by clicking Add, then typing in the URL.I also added the IP to vcenter as well. Click OK.

One more warning about the HTTP location you’ve entered. Just click continue. Apply the changes and close the java applet. Be sure to close the vCenter client as well.

Launch the client and log into VSM as usual.

Update- info on Windows 7

In Windows 7, there is no exception list under the security tab. To add your site to an exception list, you can create an exception.sites file and add the URL.

win7-java-securitytab

Browse to this location: C:\Users\username\AppData\LocalLow\Sun\Java\Deployment\security

If  there is a file named exception.sites, add the URL to that file. One URL per line.

If not, you can create it and add your URL.

exception-site

The command has timed out as the remote server is taking too long

I’m running vSphere 5.1 and I can’t launch the vSphere Client. I am able to launch the web client just fine. Upon launching the fat client, I get an error:

vsphere client could not connect

We updated our domain from 2003 to 2008 R2 and replaced all old domain controllers  (DCs). I’d changed the primary and secondary server URL (there was no port number previously) during the cut over and all has been working well for the past 26 days and today, nothing.

I logged into the web client as admin@system-domain to confirm I was pointing to the new domain controllers and I was. So now I’m really stumped. KB article 203918 solved the riddle.

Web client login as admin

To view the identity sources:  Administration > Sign-On and Discovery > Configuration. Here you can view the identity sources. Click the pencil to edit and see more detail.

Here are my current settings:

Current Server URL

I added the port number to both the primary and secondary server URLs and tested the connection. Click OK to close the dialog box.

Updated URL with Port Number

I was then able to launch the fat client without error.

Don’t forget to log out of the web client as admin@system-domain.

It’s safe to assume when I installed 5.1, I didn’t enter the port number as suggested in the Configuring vCenter Single Sign on doc and it worked just fine. Upon upgrading, the port became a required setting.

I passed the VCA

I am officially a VMware Certified Associate  in Data Center Virtualization (VCA-DCV)!

VCA-DCV-sm

Last week I attended the VMware vSphere: Optimize and Scale (5.1) class at New Horizons and after hearing from a few of the attendees that the exam was a cinch if you worked with VMware and you sat through the online VMware Data Center Virtualization Fundamentals e-learning course, you could pass the VMware Certified Associate (VCA) exam with no problem. After watching the video, reading the exam blueprint, VMware vSphere Basics guide, and taking the practice exam twice, I was ready to schedule.

There is no class prerequisite to take the VCA like the VCP5 and such!

The test is administered by Pearsons Vue and you must request authorization from VMware first to schedule your exam.  There is a PDF that outlines the exam registration procedure in great detail. Once you’re registered, signed up with Pearsons and pay for your exam ($120) you’re ready to go. There are tons of discount codes out there that will either give you a 50% discount or maybe even a freebie. Check the VCA forums and see which one works.

The test was 50 questions, 75 minutes long and for but a few questions, they come straight from the e-learning course. My advice, read the question, re-read it and focus on the sentence in the middle that gives you the most clues about what the answer may be. Did I say READ the question?  To pass, you need to score a 300. The scale is 100-500 and I got a 420.

My next stop is to study for the VMware Certified Professional 5 – Data Center Virtualization (VCP5-DCV) exam. To obtain this one, you must have taken qualifying coursework prior to obtaining your certification. In the meantime, I’ll take the VMware Certified Associate – Cloud (VCA-Cloud) & VMware Certified Associate – Workforce Mobility (VCA-WM) as well.

I’ll post my training plan and will let you know of my progress. Good luck to you if you’re on the path to becoming VMware certified.
