How To : Create a MetaLUN on an EMC Clariion CX4

Jeff Miller created a quick and dirty tutorial on how to create a MetaLUN on an EMC SAN. 

Here are the steps involved in creating a MetaLUN on an EMC Clariion CX4.
The steps below show creating 4 LUNs of size 6,400 MB which are then expanded into 1 LUN of 25 gigs.
Photos 1 and 2 will need to be performed 4 times in order to create all 4 LUNs, and I set these up as follows:

LUN 3924 Raid Group 27 raid 1+0 LUN ID 3924 6,400 MB
LUN 3925 Raid Group 26 raid 1+0 LUN ID 3924 6,400 MB
LUN 3926 Raid Group 25 raid 1+0 LUN ID 3924 6,400 MB
LUN 131 Raid Group 24 raid 1+0 LUN ID 3924 6,400 MB

I then expanded LUN 131 to the full capacity of 25 gigs by striping it across the 3 other LUNs.

Tweet, Tweet ; Just another Citrix Twitter List

imageIn a nod to Eric Siebert’s fantastic VMware Twitter list, I have put together a list of Citrix folks that I follow online.  Although Twitter seems to be popping up everywhere you turn, a lot of people find it hard to figure out how to jump into these conversations.  Sometimes, you just don’t know who to follow to get into the conversations you will find interesting.  Most twitter users become Qwitters after just a few months of joining.  I think this is primarily due to the fact that when you first start, if you are not following anyone, and no one is following you, you are basically just talking into an empty room. :)  

If you are interested in VMware or Citrix, you should check out these lists.  In my experience, most Citrix people do VMware and vice-versa and you will find some overlap between these lists.  TweepML.org makes it very easy to follow groups of people with just a click of the button.

Citrix Twitter List 2009  (70 Tweeters)                 
Eric’s Top 100 VMware & virtualization people

I think a good Twitter client is also very important for a successful experience.  I find TweetDeck to be one of the best Windows Twitter clients.  It definitely helps me organize everything via lists (Columns) and provides excellent searching capabilities.  Makes it much easier to sort through the noise.  I never really got into the mobile tweeting.. since that’s where I think a majority of the NOISE comes from.

In my opinion, Twitter catches a bad rap because of all the not so interesting tweets (I ate this, I like that, I am walking my dog, etc…), but with the right tools and a couple of useful tips pointing you in the right direction, you could have access to a wealth of information and people that you might not normally have access to.

XenDesktop Lock Group Policy Issue

image David Paoleschi sent over this great tip to be aware of when applying group policies for your XenDesktop environment. 

When locking the desktop down via GPO – if you don’t allow a user to lock the desktop then the Virtual Desktop Agent (VDA) can’t do so when you disconnect  -so the desktop doesn’t appear in the correct state to the DDC and therefore a user can’t reconnect.

While David sent this tip specific to XenDesktop, I’d be willing to bet the same behavior exists within the VMware View environment.  If anyone can test this in their View environment, please post in the comments. :)

SAN Headquarters (SanHQ) Program for Monitoring Equallogic Arrays

I’ve been meaning to post about this little utility for a while now (almost 7 months on the To-do list! Yikes!).  Chris Hahn sent me these screenshots for SanHQ for Equallogic Arrays.  The free little program gathers its data via SNMP, so you just need to make sure SNMP is turned on in the array.  If you have Equallogic PS arrays and are not leveraging this handy program, you are missing out.  Great reporting and analysis and tons of pretty charts to print and deliver to management. ;-)  Download from the link Above : SanHQ.
Check out the screenshots below :

Windows 7 64-Bit Citrix Access Gateway Client Released

Yesterday I saw some tweets about testing a Windows 7 x64 Bit CAG client :


and today I see that it has been officially released!



You might have to update your Access Gateway Appliance to support the new client though.  If you have been running Windows 7 64 bit, I know you have been waiting a while for this release to become official.  :)  Enjoy!

XenApp over XenDesktop; Are you getting the correct drive mappings?

In environments where you might be so inclined to run XenApp Published applications over your XenDesktop sessions, the default behavior for the ICA protocol is to map a client’s local drives all the way through the sessions. (Pass-through ICA)  See image below :


This may not be the desired user experience if the XenDesktop session is the user’s Main desktop.  Users might need to access files saved to the local XenDesktop drives from within their published XenApp applications.

Changing a quick registry value on the XenDesktop machine will correct this issue.  From the Support article : http://support.citrix.com/article/CTX238200

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\ClientDrive
Create the Reg Value: NativeDriveMapping
Reg Type: REG_SZ
Add the Value: True

This value will yield the desired results illustrated below :

Can’t get there with the Google Car? Try the Google Trike!

Although WAY off topic, what Google does is always interesting to me so I thought I’d repost a quick message from Marcos Velez on the Google Trike! 

From the geniuses at Google, now comes the Google Trike.  It is a bicycle modified to take the place of the Google Car that generates the Street View feature of Google Maps.  Their goal is to enable Google Maps to extend the Street View feature to bike trails and other locations where cars can't, or shouldn't, go.

If anyone is interested, click on the link below.  They are asking for suggestions on where to go next.  They also have a short silly video that shows the trike in action, and links to four locations that have already been enhanced to have Street View for non-street areas.

Help the Grassroots Citrix Community Effort


As many of you might know there has been a large movement within Citrix lately to highlight and support User Group activity. The Northeast region has always had a strong User Group in the Boston area and our local engineers are trying to build that same user community in NYC and NJ.

There is no question that a strong User community is a valuable resource to any engineer.  User groups are a great way to discover new technology uses and network with peers  If you are in the NY/NJ area, be sure to register and participate in this great event.

Click on the link to the right for all the details.

The upcoming meeting is on 10/21/09, 9am-11am, at the MSFT office in Iselin, NJ. The plan is to have quarterly meetings (perhaps shifting to every 2 months, depending on interest) and bring in additional vendors to educate on their solutions and how they complement Citrix technology/environments.

VMware Enterprise licensing rumors

imageA few of my enterprise customers have been asking me if I know anything about the recent changes in VMware licensing.  Specifically, that VMware was to discontinue vSphere Enterprise in an effort to upgrade them to the new Enterprise Plus versions.  At first, I dismissed this as harmless FUD but after a few more clients and some of my own sales reps began asking, I looked into it a bit more but couldn’t really find anything ‘official’ on VMware.com’s site.

Today on a Roundtable call with VMware, @Larstr pointed me to another blog post on VMGuy’s site that had some convincing information.  Although still not an OFFICIAL press release from VMware, this information comes from a variety of very good sources. :)

I won’t go into the gory details (you can read VMGuy's post for that) but in a nutshell, VMware WILL CONTINUE to sell and renew the Enterprise Editions of it’s vSphere license.  Rumors of its demise have been greatly exaggerated.

Hope this helps clear up the situation on licensing.   You can refer back to my vSphere Licensing Post for a refresher on the various editions and the features that they entitle you too.
