There are a several good points made my new blogging buddy, Miguel. Number one, you don’t include in your design features for the sake of features. This may seem obvious, but perhaps for a passionate (maybe overzealous!) VMware Architect, implementing features on which on-site staff are not proficient or can’t manage is not a benefit. As Miguel shares in this “palm-to-face” anecdote, such features in the hands of untrained staff can have the opposite effect for which they’re designed. So take into account the staff’s abilities before including advanced features in your design. Number two, communication is key in any environment. Communicating to the customer the gravity of the decisions they make in regards to what’s included in the design and certainly sharing planned maintenance times with all stakeholders. A communication strategy and change control process are key to making this work. Number three, as Miguel shared with me, if an admin is looking at his virtual infrastructure like a hog looks at a wristwatch, well, things are pretty bad. And finally, always remember: VMware’s easy.
I had a long-term project at a customer site where I was to analyze, design, and architect a solution based on the equipment, environment, and requirements. Before I rolled in to the customer site as the new VMware SME, there had been a recommendation by a junior and recent VCP to implement distributed switching, linked vCenters and a few other feature sets of VMware and NetApp. There was not any experience with distributed switching by the on-site staff and their exposure to VMware was minimal, although many thought themselves as experts after a few weeks with the product. I kept hearing the comment that VMware was easy. I recommended a hybrid solution with the MC using standard switching, and VM network\storage on distributed switching as a compromise to a fully distributed solution. They decided against this even after I presented them with the advantages.
A few weeks later they had…

Replacing a Cisco Nexus 2224 Fabric Extender
Posted: January 14, 2012 Filed under: Cisco Nexus, Networking | Tags: 2224, cisco nexus, cisco nexus fabric extender, Fabric Extender, FEX, n2k, replace 2000, replace 2224 fex, replace cisco nexus fabric extender, replace fex, replace nexus, replace nexus 2000, sh few, show few 2 CommentsSo my team and I got a call to swing by a customer’s site on our way to another job. They told us half the ports went bad on a FEX and we were to install the replacement that just arrived onsite. In this post, I’ll explain how to replace the FEX (which is trivial) and more importantly how to verify that it’s working after installation.

Here’s an excerpt:

How to Configure LUN Masking with Openfiler 2.99 and ESXi 4.1
Posted: December 22, 2011 Filed under: Storage, VMware | Tags: configure lun masking, configure openfiler, esx, esxi, esxi 4.1, lun masking, openfiler, openfiler 2.99 8 CommentsThis is a duplicate post on this blog but for good reason. I’m back home for vacation and my on-ramp to the interwebs is finally high speed DSL and more reliable than when I first posted several months ago. Therefore, I’m able to include my original screenshots with this post. I had to remove the screenshots in the first post because they wouldn’t upload. I hope this post will give you that visual aid that’s so helpful in walkthroughs.
I passed the VCP 5 exam!
Posted: December 22, 2011 Filed under: Tid-bits, VMware | Tags: I passed VCP, VCP, VCP 5 Leave a commentA happy day for me, indeed! I passed my VMware Certified Professional on vSphere 5 exam today in Rolla, MIssouri. I’ve been studying vSphere 5 now for about 5 months.
Because my current project is implementing vSphere 4.1 data centers, I was planning on attending the Install, Configure, and Manage course for vSphere 4.1 – I even bought the 4.1 course. Then vSphere 5 came out and my course provider, Global Knowledge, changed my 4.1 course to version 5. That was ok by me. I just changed gears and started studying for vSphere 5. I’ve been able to set up version 5 test labs at different customer sites parallel to our 4.1 implementations. The test labs have all consisted of nested ESXi boxes.
Windows Server 2003 won’t boot after a P2V
Posted: December 6, 2011 Filed under: VMware, Windows | Tags: /burnmemory, boot.ini, burn memory, converter 5, p2v, p2v will not boot, physical to virtual, server 2003, vmware, vmware converter 5, Windows Leave a commentSo far, our Physical-to-Virtual migrations of Exchange 2003 on x86 Server 2003 Enterprise boxes have gone mostly smoothly – until this evening, that is. In the past, a failure soon after the P2V process started was resolved with a reboot or by disabling the TCP Offload Engine on the Broadcom NICs (this was easily accomplished with the cmd.exe command netsh int ip set chimney DISABLED).
This evening’s P2Vs were a bit more challenging.
Installing vCenter Server does not complete with Windows Server 2008
Posted: November 29, 2011 Filed under: VMware, Windows | Tags: 2008, fails, install, server 2008, vcenter, windows 2008, windows server Leave a commentThis is a quickie post to share what I found when installing vCenter Server on a 64-bit Windows Server 2008 Enterprise Edition virtual machine. This VMware KB article is the error we received.
Apparently, during the installation of vCenter Server, Active Directory Lightweight Directory Services is installed. I hadn’t noticed this before. We had no server roles installed prior to installing vCenter, but after clicking through the error boxes that appeared, we saw that AD LDS, sure enough, appeared to be installed.
Upgrading NX-OS on the Nexus 5020
Posted: November 24, 2011 Filed under: Cisco Nexus, Networking | Tags: nexus upgrade, nx-os, nx-os upgrade, nxos, upgrade, upgrade nx-os 1 CommentDuring another virtualization implementation at a customer’s site, I had the opportunity to upgrade Nexus 5020 switches. We upgraded from 5.0(2)N2(1) to 5.0(3)N2(1). The process was surprisingly simple. The steps include
1. Setting up an TFTP server
2. Uploading both the NX-OS binary and the kickstart binary
3. Installing the binaries
The Quick and Dirty (and Free!) IP Scanner
Posted: November 10, 2011 Filed under: Tid-bits | Tags: free ip scanner, ip, ip address, ip address scanner, ip scanner 1 Comment(edit: 12Aug24) PowerShell version:
& {for ($i=1;$i -le 254;$i++) {ping 192.168.86.$i -n 1 | Select-String “bytes=32”} } | out-file c:\temp\ping.txt
If, on occasion, you need to scan a range of IP addresses for live devices but don’t have access to the many tools for such a task, free or otherwise, memorize this little trick and move on to more important things!
Open a command prompt and type
for /L %i in (1,1,254) do ping -n 1 xxx.xxx.xxx.%i | find “Reply” >> c:\ping.txt
Be sure to replace the x’s in the above command with the correct portion of the IP address range you want to scan.
The output below is what the command looks like when it’s running.
