PowersHell – Enabling FT Logging

Saturday, September 12th, 2009

I had a post/comment on my blog this week about enabling FT logging on VMKernel Port. It wasn’t immediately apparent how to do this – so I ask Carter Shanklin who is Product Manager of PowerCLI for a “how to“. True to form he’s come up trumps.  This is what he’s sent me. Not had a chance to test it just yet. But will be post it here for the folks who asked me…

# Enable or disable FT logging.
$esxHost = "192.168.1.11"
$vmKernel = "vmk0" # You can get these out of Get-VMHostNetwork
$enable = $true
$hView = Get-VMHost $esxHost | Get-View -Property configManager
$nicManager = Get-View $hView.configManager.virtualNicManager
if ($enable -eq $true) {
	$nicManager.SelectVnicForNicType("faultToleranceLogging", $vmKernel)
} else {
	$nicManager.DeselectVnicForNicType("faultToleranceLogging", $vmKernel)
}

Update:

Anyway, the original poster of that comment David Gontie got back in touch with me – with away of doing the same thing from the kickstart install %post script. Personally, I’m weening myself off my beloved COS in favour of Powershell. But here’s David’s full blog post on how its done:

vmware-vim-cmd hostsvc/advopt/update FT.Vmknic string vmk1

Where vmk1 is the second vmkernel port. I found you had to restart the management services to make sure the vSphere Client reflected the changes (service mgmt-vmware restart)…

Not used it myself – I passed the Beta Exam… But I think he’s amongst the first to produce such a practise test…

VMworld 2009: VMworld Party: Shout out to the lab guys

Monday, September 7th, 2009

Well, this blog post is for all the lab guys who did such a sterling job under terrific pressure at last weeks VMworld. I kinda skipped the VMworld Party, and saved the indignities of Foreigner. Instead I joined Mornay Van Der Valt (VMware’s Technical Marketing Manager) and the lab guys for dinner and on to the Lab VMworld VIP Party. We had a good old (but off the record) ching-wag about some of the challenges they had experienced in the week. Nothing I can repeat here, but contray to popular myth the challenges they had nothing to do with running “vSphere on vSphere”. That was proved to be successful in Canne earlier this year…

Anyway, I had one of those “British” moments where I used turn of phrase that made them all crack-up laughing. I was saying how something “honks”. Anyway, in case you don’t know when something totally “honks” it means it totally stinks. I thought I do a google-wack to prove my definition is true – it took a while but here it is:

http://www.peevish.co.uk/slang/h.htm

honk Noun. A bad smell. E.g.”It honks like shit in here, can I open a window?”

What I’m trying to work out is if it’s specifically an Northern-English term…. :-)

Anyway, after the dinner we went in search of the VIP lab party – we hung out in private area – and I got chatting to Adam Carter of Lefthand Networks/HP. For some odd reason there were rubber chickens everywhere. That put me in mind of that scene from Five Easy Piece’s where the Jack Nicolson asks the waitress to “hold the chicken between her knees…”

Here’s another video of one of the lab guys who had diner with that night. It was real good laugh. No marketing b*******t – just a bunch of guys swapping war-stories!

It’s Free – SRM Book Free PDF or at Cost Hard Copy…

Monday, September 7th, 2009

Now that VMworld is over, I will be beginning the early stages of re-writing the SRM book to be up-to-date with the SRM 4.0 product which is currently in beta. I always thought that soon as I started doing that I would make the first SRM book free to download. If you want to have a hard-copy of the book you can still request a print from LULU.com. I’ve made that to be an at-cost price (i.e the price is what it costs lulu.com print plus what ever your shipping costs are.

Update:

I dumped the previous links, because they didn’t appear to show the free PDF. This link is better:

VMworld 2009: Day Three – Meet the Publisher/NetApp Session/vExperts PowWow…

Monday, September 7th, 2009

In the morning I had a little chat with my publisher, McGraw-Hill. Nothing explosive to report except to say that we have chosen to lift the VMware View chapter out of the new book. Primarily, because I know a new version is on its way – and so I want to aviod it being “dated” before the book is even published. Secondly, both VMware and my tech editor both wondered about the placement of the chapter. Finally, it will help with page length – I need some wriggle room when the time comes for a 2nd Edition. Anyway, all is not lost. I will maintain the chapter, updating it when the next release of View comes out (4.0???) and release it as a free PDF probably around the release date of the vSphere book.

I then hung about the solutions exchange, and more specifically the communities lounge – where I bumped into a couple of folks. The upshot being the idea of User Group/Summit roadshow for Spring of 2010. I’ve been to the North Carolina User Summit twice now, and will be there next year also. But this time around the idea is link a couple of events together to make the journey more worthwhile. My hope it to tie this roadshow into a general promotion for the vSphere4 book – with luck I will be able to get my publisher to cover the costs of the events – especially if VMware buy copies of the book as “giveaways” to attendees.

I also had a chat with some vExperts about the idea of sharing lab hardware. I’ve got quite a good lab environment, and there maybe a possibility that I will get the Cisco UCS kit into my labs. Of course I would love to have HP Blades in there as well – but space/cost make having every single OEM and storage vendor in a couple of 42U racks – as stretch too far. The idea is to a number of the more public vExperts/ Partners/ ReSellers to host this kit, and give other vExperts remote access via Citrix XenDesktop or View Desktop. Anyway, for the moment its a bit of pipe dream. But the idea is give folks access to hardware which would be normally be cost/space prohibitive…

By the late afternoon it was time to head down to Room 121 (not 101!) to do a co-speaker session with Vaughn Stewart of NetApp. The topic was about how storage faciliaties DR/BC. Generally, it was an overview of the various DR/BC technologies – and attempt to map their advantages/disadvantages. Vaughn was the host, and chipped in a long the way with various opinons and questions. I hope we were useful to the group. Generally, it seems clear to me that people need a blend of solutions – as there is no killer application here. But folks have got to appreicate the sometime contradictory requirements of one technology when used with inconjunction with others.

Directly after that event we were in the same room for the formal vExperts meeting – there was some 50-100 of use. We were presented with certificates and fancy vExperts pen. Steve Herrod of VMware was there too, unfortunately there wasn’t a formal presentation and photographer there – so there aren’t “grip & grin” photos of me with Steve Herrod. We were able to fire a couple of questions at the CTO, and of course I wasn’t backwards in coming forwards with questions and opinons!

Firstly, he made it clear that VMware has NO intention of offering its own in-house vCloud Express service. VMware is about creating products that allow partners to deliver the cloud – and guess the announcements the day before of a dizzing array of cloud providers using vSphere4 makes that plain. Steve also said that VMware are looking to decouple the vSphere4 client from .NET to allow for a client that runs on many platforms – (Ed, erm you mean Linux?). He poo-poo’d the idea of giving away VMotion and other features for “free” to more aggressively compete with Microsoft – but pointed to the existenance of various “essentials” packages and VMware GO – as signs that VMware are offering value for money for the SMBs. Finally, he acknowledged that more work has to be done with various VMware Virtual Appliances (vMA, MM, VDR) to standardise on a single GOS for these systems – to allow for better maintenance, patch management and updates.  After Steve Herrod left we given presentations by Steve Kaplin and Jason Boche. Whilst Steve Kaplin was very enteraining on the subject of evangelism, I’m not sure if I would 100% agree with his ethos. He suggest that being able to “use” other people to further your own career was a good thing – and that evangelism was about promoting oneself as much as the subject of evangelism. I know I’m no shrinking violet when it comes to self-promotion – but I had hoped my own evangelism was less self-serving. My pal Jason Boche was much more self-affacing, and such went up in already my high estimation. Jason is new blogging and twittering after being urged to contribute beyond his already active VMTN forum contributions by John Troyer. In his own laid back and laconic style, Jason explained how he’d accrued about 3 binds of useful/practical virtualization knowledge over the last 5 years. Basically, the basis of his blog is to convert that into electonic form we can all access. A man after my own heart – anyway, if you’ve not visited Jasons blog it’s here:

http://www.boche.net/blog/

On the subject of vExperts. I think its perhaps a good time to make clear what the programme is about because in away the title is perhaps a bit misleading. vExperts is not a technical programme – although it quite frequently has members who are hands on like me. There are some vExperts who have contributed to the VMware Community in other ways such as running user groups. So in away is more a community recognition programme.

In the evening I hung out with Mornay Van De Valt and his Lab Masters. But that as they say is another blog post. Probably directly after this…

VMworld 2009: Day Two

Monday, September 7th, 2009

Well, I’m back in the UK but I thought I would catch-up on some blogging. On Wednesday I had a meeting with Hannah Drake of TechTarget.com. Just informal chat about the possibility of me contribiting to their site. I’ve got this idea for a VMware PowerCLI web-page that makes hyperlinks of all the cmdlets that currently make up the PowerCL (some 160 cmdlets in total). I got the idea from picking up a wall chart (now in up on my office wall). Idea would be to “mark-up” the wall-chart with each cmdlet having a link to a cool example – I want to try and aggregate some of the PowerCLI stuff from my own and other peoples sites – to give one handy place for sample and example. The other idea I had was a day-by-day or week-by-week guide to PowerCLI, starting with the absolute basics – following into step-by-step guide to the SDK.

The rest of this blogpost isn’t really technical but social – so read on McDuff if your bothered.

Halfmode’s XenServer Documenter

Monday, September 7th, 2009

A pal of mine has put me on to a new utility called XenServer Documenter. To quoth the blurb “provides a time saving solution for making detailed documents of Citrix Xenserver infrastructures. It highlights a plethora of configuration parameters in neatly formated tables and constructs a professional looking Microsoft Word 2003 or Word 2007 Document”

VMworld 2009: Day 2: Boob/Booth Babes

Thursday, September 3rd, 2009

My friend Gabe, and his partner are here for VMware VMworld. Gabe’s partner is called Brenda and she’s become the poster girl of the virtualization twitter community. When I first met them in Canne I dubbed them “Gabe & Babe” :-) Anyway, Brenda has anthropological so she has been studying the virtualization community for sometime. This kinda makes you feel like we are some obscure African tribe which has only recently been discovered in the mountains.

Brenda’s subject of study this year – is the “Booth Babe”. She’s been going around chatting/interviewing them whilst she fulfils her duties on the Veeam booth. I know what you guys are thinking. Gee, that must be so difficult going around interviewing this hot-chick who just can’t wait to enter you in a lottery to win a Segway. I don’t quite if Brenda has got round to definining what makes a booth/boob babe but she must be making progress. If you haven’t a clue what I mean. Here’s a sample of a booth babe. The strategy must work to pull in the guys otherwise these ISVs/OEMs would hire them. But its quite odd the way the fellas hang around them in a very sheepish (Ed. don’t mean creepy?) way!

Anyway, I asked this lady if I could put my hand on her shoulder for a nano-second for the photo. And I was told firmly, not very politely – NO. My reputation must preceed me…

VMworld 2009: Day 2: PowerShell Session

Thursday, September 3rd, 2009

Well, actually its day 4 now so I’m a bit behind in the blogging. Don’t worry I’ve made copious notes of the various things I’ve done. So there will be blogfest offline on the plane if the in flight movie options don’t do it for me.

So you know powersHell and the PowerCLI right? No? OK, don’t worry about that – I’ve got something in the pipeline planed that will act as a door opener for all those who have yet to dip their toe into the powersHell waters. For those you have. The news is that were will be a new version of PowerCLI – 4.1 by the end of the year. Expect all so that then there will be ESX4.1/vCenter4.1 release. More or less the powerCLI development is dictated by the release strategy of the platform it manages.

I forget exactly the current number of PowerCLI command lets (150/160) but even more will be added into the PowerCLI at the 4.1 release. Including cmdlet to handle iSCIS (Yeah!!!) and to handle the NIC Teaming Policy Settings (Double-yeah) all of which require good knowledge of the SDK, a map and torch OR alternatively you download mine or any number of other bloggers PS sample and pretend your boss you did it all by yourself. WE KNOW WHO YOU ARE! :-)

Also on show was a demo of Onxy, which has been put together by the Bulgian Dev team inside VMware [These guys are truely international!]. The demo wasn’t much more than what shown on the VMW site – which embedded into my blog a couple of days ago. In case you haven’t see it yet, Onxy is like a macro recorder which sits between the vSphere Client and vCenter “recording” all your interactions – leaving you with a cut and paste job on the PS code window.

http://www.rtfm-ed.co.uk/?p=1643

I made a point of attending the session so I could hand in my business card (actually tore strip of my paper keycard from the Marriot, and wrote my name on it) to be entered into a lotto to join the Alpha programme. Some of the PowerShell Gurus like LucD and Hal Rottenberg were a little word that exposing the SDK so easily might be a little “dangerous” in the wrong hands. But personally, the cmdlets can do as much (if not more) damage before you even get to the SDK. For instance I could write powersHell that shutdown all your VMs, deleted them and then your datastore. The only thing stopping that is a little old thing called a username and password.

Also on show was www.thevesi.org (free community supported product the brain child of VizionCore and Scott Herold – my co-author on the Vi3 book). Its much higher level version of the PowerGUI front end. Like Onyx, VESI gives you a graphic front-end (not the vSphere client) which carries many “bulk admin” tasks – and leaves you with a PS window ready to be cut & pasted into a PS1 file. I was quite empressed by the VESI. Especially the chart and VISO output features. It’s the kind of thing some folks wind-up paying for,  whilst the VESI is for free…

VMworld 2009 – Day 2: Keynote Steve Herod

Wednesday, September 2nd, 2009

Well, this is actually a bit of an experiment or joke if you like. I didn’t actually make the keynote. I was out drinking with a buddy from England last night who haven’t seen in 2 years. We had some great mexican food and got to shoot some pool. Almost won my game, but fluffed the finish on the black.

Right now I’m in bed in the hotel, I ignored the alarm I set for 7.00 to get me to the keynote at 8am. Never understand the conferrence circuit. They get you drunk on the evening, and then expect you up at 8am. Personally, I think conferrences should run more like 11am-2am (the next day). Giving attendees plenty of time to process their alcohol intake.

But anyway, I’m not at the keynote – but I’m going to write a blogpost based on the twits of my fellow bloggers. Hey, maybe I will do this next year – after all you don’t have to write anything original if your a blogger just canibalise everyone else material. Right? ;-)

So anyway, Mr Herrod has stepped up to the stage. And right of the bat present the standard vMware slide – you know the one with vSphere4 in the middle and individual piece plug in like parts of the jigsaw. To the sound of “I like to move it, move it”. He announced that VMware will be extending the functionality of DRS to include the SVMotion of VMs from one datastore to another to improve performance. As with VMotion/DRS subtle calculations based on the IOPS of each VM will be used to control if the VM gets moved – in a process dubbed “datacenter defrag” (I heard that buzz word yesterday at the private press (non)event.

Next Herrod demo’d config control. It has a web-based admin tool that seemed to irratate some of my fellow twits/bloggers. The argument being that this marks a deviation from the vCenter plug-in strategy. Personally, I’m in two mines. Web-interfaces means I don’t have to worry about install/upgrading client front-ends – and conflicts in versionings (Vi Client anyone?) but the problem with WI is they tend to be a bit clunky, lack in feedback – and fininky about what browser your using (does anyone like me have 3 different web-browers installed in case one doesn’t work well with a web-site?)

It was this time I lost site of the VMworldPress Wifi in my hotel room. So I had to stop. I will continue when I get reconnected.

Anyway, then I got back on by then. The keynote had finished, but fortunately tweet deck still captured all the tweets. It sounds like Herod repeated the stuff at the Paul M session yesterday – Iaas, Saas, Paas. The alphabet soup prompted some commentors to demand BaaS – (Breakfast as a Service!). Clearly this early morning session had denied them the sustance they needed. Meanwhile I had my breakfast in bed. Yum. Also Herod demo’d the long distance VMotion that was shown at Paul M session. Somewhere in the break outs is a “Long Distance VMotion” session. It’s TA3105 on Wednesday (today) at 4.30pm. My pal Chad Sakac is there, (un)fortunately I will be co-presenting – so I will have to get a re-wind on the session when these videos appear on the VMworld 2009 website…
