ESX on Dell R710 – vSphere-client not connecting

admin — Tue, 22 Jun 2010 07:24:22 +0000

In my case it had something to do with the Drac-configuration. I had to disable “System Services” in the drac-menu.

The weird thing was, that i have 2 identical servers, and only one of them had them problem.

Know your way around in the vCenter GUI. There are some questions in the VCP4-test regarding what options you have different places in the GUI. Go through all menus and options, and know what they are there for.

An example could be: What is the default setting for “Default cluster settings” under VM monitoring in the HA-configuration?

1: Low

2: Medium

3: High

Free apps you cant live without as a sysadmin (Part 3)

If you have been fooling around with ESX(i) you might know putty. “PuTTY is a free implementation of Telnet and SSH for Windows and Unix platforms, along with an xterm terminal emulator” as the homepage states. I use this app every day to manage Linux-servers, firewalls, routers and offcourse ESX-servers. You can choose to install the “putty-package” with is a set of apps for use around putty.

I use pageant all the time. Pageant is “an SSH authentication agent for PuTTY, PSCP and Plink”. If you want to know about how it works take a look here.

First of all, know your maximums! Its not that big a part of the test but its is easy point if you can memorize them. Memorize this whitepaper and take the the practice exams that on Simon Long’s blog until you get them 100% right. That helped me alot.
