1. Backup

It is very important step. Everything is on you risk, but Always Always Always backup is needed in any circumstance. Don't make a situation to pull your hair in your failure. Definitely not a good thing.

We have installed Veeam FastSCP free version. Yes it does support Free ESXi 3.5 and 4.0. It is really fast compared to other ways to back up and restore.

Also, before starting upgrade your Free ESXi3.5, power down all the guest OSs and put your ESXi 3.5 on "maintenance mode"

 

 2. Download upgrade package

You need to download ESXi 4.0 upgrade package from the VMware website. The file looks like "ESXi-4.0.0-xxxxxx-upgrade-release.zip". You need to register, not just only get the package, but also getting ESXi 4.0 licenses.  


 3. Download Free vSphere Client 4.0 

You can download vSphere Client 4.0 from VMware website, or you can extract it from the ESXi 4.0 package using 7-zip manager. See the path to extract below picture.

We saw Solarwinds provides good free tools, and tried to test a Solarwinds Netflow Configurator, but never chance.

Today, we installed it as fly and then..... We got below alers while we were trying to test Netflow Configurator with Cisco 7200 with Version 12.2(13)T16.
 

"The specified credentials do not have both read and write permission on the device. You must specify credentials with read-write access."

Isn't that too real on subject? I hope! cisco_logo.gif

I believe that at least some of you guys agree with me here. If someone is preparing for CCIE lab exam, more than few hours typing same commands all over again. I don't want to use too many alias commands, but 5~10 alias for essential commands would be really help. You should try it.

Here is aliases I am using it.

s = show ip int brief
si = show run int
sr = show ip route
r = show run
proc = show processes cpu | excl 0.00%__0.00%__0.00%

Synergy software is well known utility for sharing keyboard and mouse while using two or more logo_Synergy.gifcomputers at the same time. I love this software rather than using KVM switches... try this it is really handy software. By the way, today I got weird error message while I was configuring Synergy software.  I couldn't save my configuration and kept on getting below message.

" Failed to save configuration: Access is denied "
