  • VCAP-DCA Study

    I found over the years that I don’t really know something until I can teach it to someone else. I plan on writing some new posts inspired by the VCAP-DCA blue print. Here is some good resources based on the VCAP-DCA Most of my old VCDX study notes are based on the VCDX3 path. http://www.simonlong.co.uk/blog/vcdx-study-notes/ […]

  • My Fun with the VMware Enterprise Administration and Design Exams

    Sorry I have been missing for a few weeks. I know many were quite worried why I hadn’t blogged for a couple weeks (not really). Back in February I sat for the Enterprise Administration Exam at PEX in Las Vegas. It was scheduled the day after the Super Bowl, what a bunch of distractions. Thankfully […]

  • ESX Commands: esxcfg-vswif

    The esxcfg-vswif command allows you to create and modify Service Console ports and their IP information. Many times I have to change stuff after the install process is complete and the only place is via the direct service console because network communication is not possible. This usually happens when the network team changes a vlan […]

  • ESX Commands: esxcfg-vmknic

    You need to have VMkernel ports to do VMotion, Software iSCSI and Fault Tolerance. These ports can be easy to create and manage from the command line. I generally can be found adding them for vSphere iSCSI. I especially use the cli for tasks that are repeated over and over. Creating multiple ports per ESX […]

  • ESX Commands: esxcfg-vswitch

    This is a command I use the most often. It is big when I configure Equalogic and MPIO in vSphere. Additionally, many times I show up on site and the network is not configured prior to my arrival. Even if I sent all the configs ahead of time. People like to wait until the last […]

  • ESX Commands: esxcfg-pciid,rescan,resgrp,swiscsi,upgrade, vmhbadevs

    I have been writing on ESX command line stuff for far too long now. I just need to finish it before ESX 5 comes out with no command line support and my year long series is rendered obsolete before it is finished. Here is a few more commands from ESX 3.5u4. They are pretty short […]

  • ESX Commands – esxcfg-nas

    esxcfg-nas Standard use of this command is to add or list your NFS mounts. List: esxcfg-nas –l Add: esxcfg-nas –a –o <host> -s <share> <name> Not much more I can say. A little more detail here: http://b2v.co.uk/b2vguide2vmware3.htm A thread in the communities about a problem someone had where the nfsclient wasn’t loaded: http://communities.vmware.com/message/864559 So go […]

  • ESX Commands – esxcfg-mpath

    It has been almost 1 year since I started looking at the esxcfg-* commands. It initially came as a look at the first part of the Enterprise Administration Exam’s Blueprint very first bullet point. In that post I talked about using esxcfg-mpath to identify which luns are fiber, iSCSI, NFS or local. Today lets look […]

  • Rescan All Hba’s Where are you?

    So I was updating some of my blog posts on the esxcfg-* commands with any changes in ESX 4. I wrote earlier I did not know much about the esxcfg-advcfg command. Since writing that post at the end of 2008, I found Duncan Epping used esxcfg-advcfg in 3.5 to set the option rescan all the […]

  • ESX Commands – esxcfg-module

    After the last two entries being somewhat boring and not useful at least in my opinion. I am glad this command has a little more to it. [root@esx1 root]# esxcfg-module -hUsage: esxcfg-module -g–get-options Get the options for a given module and whether it is loaded on boot. -s–set-options Set the options for a given module. […]
