vExpert Lior Kamrat over at http://imallvirtual.com has posted a script for deploying VMware View Linked Clones.
I did a vBrownbag podcast at professionalvmware.com on a very similar technique of using Excel to create batch files for automatically generating all the PoSh and PowerCli code for deploying fully automated, non-persistent linked clone pools (with replica tiering) managed by a single AD Global Group.
Lior’s script is a great next step if you are ready to move past batch files, check it out.

I am very excited that I was awarded the the 2013 vExpert. This distinction rewards the contributions and efforts to advance the virtualization and cloud computing community. It really makes the the extra work put into social media, VMUG events for the Dallas-Fort Worth VMUG and public speaking events worth it.
Have I mentioned what a pain getting food delivered for 150 people can be? 🙂

So after an excruciating 3 week wait, I got the results of my VCAP-DCA exam. I was positive I had failed because I accidentally ended the test 30 minutes early!
After reading Sean Crookston and others, I used the strategy of quickly clicking through the questions in the exam and writing the tasks down, carefully noting if the task was a build task or an admin task, and tackling the build tasks first. The test was tough, but do-able.
When I got to the 30 minute mark, I decided to click through the 5 tasks or so I had left and pick the easiest. When I clicked on the last question, I accidentally clicked “finished”! There was no “Are you sure?”, just boom, done.
I walked out sure I had failed.
Three weeks of gnawing self-doubt later and plans on when to re-take the test ($400 man!), I got my notification that I passed. Whew. The moral of the story is- don’t be an over-clicker!

Here is the SlideDeck and the SpreadSheet from my presentation at the vBrownBag on “Automating View with PowerCLI”
If you have any questions after the presentation, or you’re a lurker like I am at professionalvmware.com and watch the recordings well after the fact, feel free to leave a comment or email me at root (at) vhipster.com.

I passed the VCP-IAAS test today. I wasn’t that bad of a test, as long as you have plenty of lab time. Make sure you really got your head wrapped around the networking of vCloud Director if you want to pass this exam.
The part I was weak on was the Chargeback stuff. It’s more expensive to license Chargeback, so I haven’t played with it much.
Quite a mouthful, eh? If you have a chance to add some SSDs to your blades, though, I think you will be happy with the results. See the VMware vSphere 5.1 Documentation Center for details on how ESX uses write back cache for virtual machine swap files.
First, get some SSDs and put them in your B2XX series blades and configure a local disk policy. I was lucky enough to get two drives per blades, so I set the local disk policy to RAID1.
You could go with RAID0, but I plan on using the local disks for A/V offload with vShield End-Point protection, so i wanted a bit more surety.
When the blade boots, you will be dismayed to see your new disks listed as “remote” during the ESX install. This is expected, see Scott Lowe’s post on it for an explanation. It isn’t a problem unless you are trying to use your disks for the ESX scratch disk- we are going to be using the disk for VM swapping, not the ESX Host, so we have one less step to do- see here for a vreference.
Finish your install and either drag the ESX box into vCenter or connect with the tools directly to the host. Create a new datastore from the local disks as you usually would. I recommend using a meaningful name, like _Local_SSD. If you use Host Profiles, you will want to uncheck the relevant checkboxes under Storage before pushing the Profile down to other hosts.
With your host selected, go to the “Configuration” tab and look under “Software”. You see a new link called “Host Cache Configuration”. Click it, and you will not see the disks you added.
Oh joy, we get to play with Putty. Connect to your host with Putty (don’t forget to turn on SSH in your security settings) and get ready to paste some commands. Leave your VMware tools showing “Storage”, you will want to refer back here for the super long naa numbers.
At this point, I could point out the numerous ways you could use PowerCLI, scripts or the vMA to do the same thing, but I think it better to learn how to do it from the command line first. Let’s get an understanding of the big list of values we are trying to manipulate first. We need to add a new value to the list of possible “Storage Array Type Plugins (SATPs)”. Refer to this great post by Stephen Foskett for more on SATPs and the PSA.
Type in “esxcli storage nmp satp rule list” into your putty session and hit enter to see all the SATPs your host knows about:
~ # esxcli storage nmp satp rule list
|VMW_SATP_ALUA_CX||DGC||CLARiiON array in ALUA mode|
|VMW_SATP_ALUA||NETAPP||NetApp arrays with ALUA support|

|VMW_SATP_LSI||SGI||IS600||SGI InfiniteStorage 4600|
|VMW_SATP_LSI||SUN||SUN_6180||Sun Storage 6180|
|VMW_SATP_DEFAULT_AA||IBM||2810XIV||IBM 2810XIV arrays without ALUA support|
|VMW_SATP_DEFAULT_AA||Fibre Channel Devices|
|VMW_SATP_DEFAULT_AA||IBM||SAS SES-2 DEVICE||IBM SAS SES-2|
|VMW_SATP_DEFAULT_AA||IBM||1820N00||IBM BCS RSSM|
|VMW_SATP_LOCAL||RAID Block Devices|
|VMW_SATP_LOCAL||Parallel SCSI Devices|
|VMW_SATP_LOCAL||Serial Attached SCSI Devices|
|VMW_SATP_LOCAL||Serial ATA Devices|
We need to add a line to end of this list, so that your SSD disk (which ESX is seeing as a SAS disk on the SAN) can use the “VMW_SATP_LOCAL” SATP. First, we need to get the naa of your drive. Look in the VMware tools at your disk, click on “Manage Paths” and you will see the naa number. In this case, mine is “naa.600508e0000000006c793530aa10e80e”. You can get this in Putty, but I like to check in the GUI, because Putty can be hard to read. Don’t bother typing it out, enter:
~ # esxcli storage nmp device list
~ # esxcli storage core device list -d naa.600508e0000000006c793530aa10e80e
The “Is SSD: false” is what we need to change. We want to add a new rule for the VMW_SATP_LOCAL SATP, one that has option=enable_ssd
~ # esxcli storage nmp satp rule add -s VMW_SATP_LOCAL --device naa.600508e0000000006c793530aa10e80e --option=enable_ssd
If you up arrow a few times and enter “esxcli storage nmp satp rule list”, you’ll see a new line at the bottom.
VMW_SATP_LOCAL naa.600508e000000000bd5fc37cdb32b60d enable_ssd user
Now unclaim the device
~ # esxcli storage core claiming unclaim --type device --device naa.600508e0000000006c793530aa10e80e
and finally reload and run the claim rules
~ # esxcli storage core claimrule load
~ # esxcli storage core claimrule run
Now lets see if it worked
~ # esxcli storage core device list -d naa.600508e0000000006c793530aa10e80e
Now add some VMs and browse the datastore to see your new swap files, and make sure to show the SAN guys on your team how you’re saving precious SAN resources.
See New Live, Online Training Helps SMBs Running VMware Overcome Limited Time and Budget for Training for details. They left out the most important thing- does this qualify you to take the VCP exam?
Its the younger administrators in SMBs that need the VCP more than anyone else. I hope they are making it easier for people to qualify- please keep the test hard though!
I’ve done a ton of VMware View deployments, so I went ahead and got the VMware Certified Professional 5- Desktop. I wasn’t that difficult of an exam if you have experience with the product. The only part that was hard is the questions about sub-optimal setups- like doing full clone desktops. I hate full-clone desktops and always go linked-clone if I can.
I plan on taking the VCAP5-DT as soon as it comes out. Since I do a lot of PowerShell and real world deployments of View it makes since. my secret plan is to get the VCDX and be one of the first VCDX Desktop guys.

Better late than never, View 5.1 is now compatible with vSphere 5.1! I wonder if they share an interface now…
Posted in Uncategorized on October 18, 2012
I did my first production deployment of vCenter 5.1, and sure enough, there was a glitch. The admin of the system changed his mind on the VLAN scheme after Single Sign-On, the Inventory service and vCenter components were setup on a linked-mode DR vCenter. I didn’t have to do every step of KB 2033620 but it sure helped.
The new web interface sure is slick, but I keep bringing up up the old tried and true interface. VMware View sure has put me off of Flash, thats for sure.
SSO is not fun.
