Updating a Garmin Nuvi? Got "No detailed maps found that support routing. The nuvi cannot be used without them"?
However, I have a solution for you.
The update to your Nuvi failed, and the maps are not on it.
Take your Nuvi, and press on the message (which nearly fills the screen) for about 5-10 seconds. The message will then disappear. At this point you (if you have a password on it) will have to unlock the device.
Then attach it to your computer, it should now appear, and the updates (using garmin express probably) will then continue and complete.
Your brick should now be functional again.

#NetGear, #ReadyNAS, virtualisation and it's support penalties (a draft from a few months ago)
We don't yet know what went wrong, but we do know it stopped talking to the LAN for management and the Private SAN about 21 1/2 hours ago.
I got it working again by lunchtime, but then about 90 minutes later it dropped out. Permanently it seemed, so it was time to call out the big guns.
A tech support call later had someone on the phone from Holland to help sort things out, but that introduced some fun.
As the NAS supported the infrastructure at this site, including the gateway server, and email - there was to be no email, and no remote control sessions in the normal course of events,
And, as the ADSL links are in the other building a physical link into the back of the router was not possible.
This is what I needed to have working:
-1. A tablet working and connected to the Internet without using the main LAN
0. An email account (outlook.com at the moment) through which I can send and receive emails outside the infrastructure to the support team.
1. A laptop connected to the DMZ directly (which is physical, not virtual) and able to connect to the Internet.
2. A wireless connection to the internal LAN that could attempt to talk to the management interface of the ReadyNAS.
3. A serial cable to plug into the ReadyNAS for telnet connection and direct management.
4. A USB to serial UART converter
5. The drivers for the converter!!!
6. Network cables that would reach from the laptop to the ReadyNAS, from the laptop to the DM'S Hub, and from the ReadyNAS to the DMZ hub.
7. Patience (there was a nearly 4 hour break in communications with support when they did not answer my updates or emails #fail
8. Access to http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu for instructions on how to reboot the ReadyNAS into different modes (watch out for factory reset!!!)
So, would you be able to get this running in under an hour?
Do you even have a serial cable in the office now?
If you do, do you have a computer (that you can then connect to the Internet) with a serial port on it?
Thankfully I did, but I might easily not have.

Verified By Visa - a security joke. But, by the way, their normal UK landline is 0247 684 2063
- 12:04pm (2 minutes later!!!) £5 at a wildlife park – this went through
- At 12:07 just under £2k to a Barclaycard account (not mine) – this was blocked
- At 12:20 86p at Experian – this went through
- At 12:36 a second attempt at the Barclaycard account – still blocked

Device upgrade - how #Apple was a #Fail and #Microsoft was a #Success
Monday, November 07, 2011
With #Apple it doesn't "just work", in fact it can fail and they can't help you. Don't upgrade to iOS5 without reading this.
- Backups are hidden away in your application data folders on Windows machines.
- Backups may demand 20GB, but then only consume a few MB, but even if they only need a few MB you need that 20GB free first.
- The backup before an iOS upgrade may remove all previous backups so that you have no fall back to iOS 4.x
- The backup before an iOS upgrade is necessary (and if you cannot do it – you get a warning that it is a risk), however it is not verified, may fail, and you’ll not be told that the backup is bad before the Upgrade continues anywa, overwriting your setup.
- Whilst Apple completely control the environemtn (hardware, software, app admission) their Tech Support says that in-app data or settings may corrupt a backup and make recovery impossible. And that’s not their fault, or their problem to fix. Apparantly it’s mine.
- some (like iA Writer, PhatPad etc) backup into the cloud with DropBox
- some (like Pages etc) can backup through the File Sharing in iTunes (although in my experience not all your documents are exposed and therefore available to backup under iOS 4.x)
- some will have iCloud backup after you get to iOS 5
- some have the means to email yourself settings or data (and I do this)
- some apps will store your settings in the cloud at their own services (Echofon, Feeddler using Google Reader for instance…)
- Paid for Microsoft support
- An upgrade to an OS that fails
- Microsoft support talk you through using Microsoft supplied tools to backup the system and implement the upgrade
- The upgrade fails and you cannot restore your computer
- Microsoft say that the failure is no longer their responsibility and that you are on your own, and wish you good luck with it.
Where do iTunes backups go on a Windows PC with redirected folders? After 70 minutes with #apple support iTunes for Windows #fail again. #Mobius

#VMware #vSA appliance, the stupidest pricing decision I've seen in a long time...
Many installations of virtualisation have a bunch of servers, but no separately installed network storage on which the VM's can be stored. This means that VM's are tied to the host on which they are running. Amongst other disadvantages, it means that if the host fails, the VM's go. It's a bit like the old physical days, lose the server, lose the service.
In a decently configured SAN setup, HA will cause any guest servers to be restarted on other hosts, subject to certain conditions - but in principal provided you have both a) the capacity and b) configured it correctly; then your network servers will be back quite quickly.
If you factor in Fault Tolerance (or guest server level resilience like Exchange DAG's) then users might not even notice an outage. Perfect.
The vSA gives the owner of servers without a SAN the benefits. Internal storage on the host servers is consolidated into a single space available to all hosts. In the event of a host failure, the other hosts still have copies of the VM guests and can bring them back quickly.
But the conditions/requirements attached to this are somewhat, ahem, interesting,
1. You must have RAID10 configuration for the internal storage.
2. Each server must have 4 GB Ethernet ports to provide triangulated connections to the other 2 servers (the vSA is aligned with the SMB editions and only runs on 3 servers).
3. Best practice is that the vCentre should not run on the vSA. VMware staff at VMworld suggested it run on a separate box outside the cluster - how 2008!!
The consequences of this:
1. To provide (say) 3TB of usable storage the installation will need 12TB of raw disk space.
2. You need to re-use an old box (hardware support contract anyone? RAID support anyone? Driver support anyone?) to run the vCentre server. And don't forget, this "old" box has to be 64bit!!
3. You need to invest in 6 dual port NIC's (you could get quads, but better to spread the physical risk across 2 cards per server).
4. You should have a separate GB switch to link up the vSA so that there is no LAN traffic impacting performance, and your SAN traffic is secure.
You then get an under the covers SAN running across all the hosts and provisioning storage for your VM guests.
Lets's say £100 for each dual NIC card, and £200 for each of 12 1TB drives. That's £3,000 in total.
The alternative of say, a NetGear ReadyNAS 3200 (other SAN's are available!) with 6TB raw disk space providing about 3.5TB available in a RAID6 style configuration. This can be got for around £3,000. I'd put a second dual NIC card in the SAN to give resilience for the SAN connections, and another 2 resilient ports for a network management interface; say £175 (it's special, it's for a SAN). You'd need the switch still, and I'd certainly consider two NIC cards in the server for physical resilience. So let's say will still get the 6 dual NIC cards for £600 total again. You might also want a pair of disks in each server to provide a RAID1 mirrored boot drive, but as you can boot ESXi from USB I'm going to say no (we are in an economy drive after all)
This means the SAN is going to set you back about £775 more than the vSA cost (or about 25%).
Oh, but wait, i forgot something. The vSA licence costs money. A shade under $8,000, or say (and I'm being generous) about £5,000. But hold on, if you're a new customer and buying VMware for the project, they'll give you a whacking 40% discount. So let's call it £3,000.
Your 25% saving by not buying the SAN has just turned into a 125% premium cost.
What the %^]{ were they smoking when they came up with that idea???
Not only are you paying more but:
1. Your ESX servers are spending valuable computing resources managing a virtual SAN across themselves.
2. Your ES servers are also spending valuable computing resources handling data from the virtual SAN.
3. The setup is so intertwined (vSA is managed by vCentre, as are the ESX hosts themselves) that VMware recommend you host it off the cluster - so the vCentre server is more exposed to risk, and an additional cost and burden (which I've not coated)
4. By recommending a physical vCentre server VMware are exposing you to all the problems of a physical server - which they would normally rubbish.
5. If you hosted the vCentre on the VMware cluster then if everything was shutdown, you might not be able to start your servers up again. No risk there then :-)
I am appalled.
If the licence was a factor of 10 cheaper then it might be worth considering. But for any business looking at new kit for a virtualisation project, steer well clear.
If (as VMware said in targeting the product) you are worried about managing another box then a) you have to in this model - the vCentre and b) get some training or good support for the SAN. If you truly think managing the SAN is going to be a problem, then managing the ESX farm as well will be. So get someone in to do it for you.
VMware - I expressed concerns directly to you this week about your perception and targeting of SMB's. This proves it to me.

PS all numbers in the article are top of the head recollections not Internet searched latest figures. But they serve to prove the point.

In case you missed my tweets yesterday from the #VMware Licencing session...
Message from #VMware ref licencing 5. It's so complex, we've written an plugin for it!
Message from #VMware ref licencing 4. We've introduced a paradigm shift where software can alert you to the need to send us lots of money...
Message from #VMware ref licencing 3. We really thought hard about making it easy, but thought you should have to think hard too.
Message from #VMware ref licencing 2. You really need to reduce the RAM assigned to your VM's until the pips in the guest squeak.
Message from #VMware ref licencing 1. We really want you to pay for your test labs/spare VM's that you spin up. Best minimise your VM farm.

Honestly #Apple are you seriously not letting me control content on an iPad
1. The iTunes PC that it connected to is no more. So now iTunes insists that the iPad is managed by another computer and my only option is to wipe and start again. No thanks.
Yes I can push most of my data into the cloud with the majority of my apps, but there are some that are on the iPad only, and they don't expose their documents to the download feature in iTunes. So unless I email content to myself from the iPad, I may lose data.
What is worse, I've no way of identifying what I shall lose until it is lost. I now need to laboriously go through apps to check content.
But I suppose at least the app store now identifies what apps I've not installed.
2. Volume of content. Photos and music I have a-plenty, too much in fact. So I wanted to remove some. Seems I'm not alone in wanting to do this, and not having the means.
It seems insanity itself, that if away from the PC/Mac that "owns" the iPad then I cannot remove photos I no longer want, remove albums that are only copies of CD's I own so that I can create free space for new content. Instead my device can just run out of space and the only route is to delete apps, which by comparison is a piece of cake.
Nanny state gone mad.
Add those two together and you get a seriously frustrated user whose previous jibes at the fanbois are going to take on a much more serious edge now.
It's ridiculous that the owner cannot exercise sufficient control of their device.

Hmmm #Windows8 #IE10 Certificate issues - anyone seen incorrect revoked
a) it works!
b) it boots in under 20 seconds (and that's with a normal BIOS, not UEFI)
c) it installed in about 15 minutes from a blank disk to a logon screen
However, working from home, I was working with Outlook on the box and got some problems so thought I would hit the OWA site for my email, when I did so, I got this:
That was a bit of a showstopper!
So I've done the usual google thing, nowt.
I've tried the Outlook Anywhere connection - fails.
I then VPN'd into the network, and hit the Exchange CAS server with the local name and logged on fine.
So the certificate is not revoked.
Further supporting evidence is the fact that ActiveSync is still working on the phones, and I can use OWA from the iPad.
So, anyone seen this? Got a fix? The only clue I can think of is that the certificate is for a non-standard name; it's not for www but owa.
Ta, Peter

#LFMF #PowerCLI Get-Folder contents #PowerShell
Because a “copy folder from the Datastore browser” backup of VM files is so inefficient, I’m writing a PowerShell process to improve my backups of the virtualised world. Because I can move VM’s around onto different storage locations a hard coded “goto this datastore, download these VM’s” is going to need rewriting every time I do this.*
So I resolved to use as a starting point the Get-Folder command (and spawn a generic process for each Folder) that I have.
So I started to look at a folder (from the VMs and Templates view, not Hosts and Clusters) to do some testing on. As the only, completely non active folder is Templates, I thought I’d start with that.
So the line of code I was looking at was something like:
Get-VM -Location (Get-Folder Templates) | Sort Name)
However I was getting nothing back, the code would run (there’s a lot more, but I won’t bore you with it until it’s all working), and there was a null result. I didn’t quite spend days and days looking at it (see King Crimson - Indiscipline, Lyrics here), but I did spend quite a while thinking I’d got something wrong.
Then I had a thought – isn’t there a Get-Template command too?
Coded like this:
Get-Template -Location (Get-Folder Templates) | Sort Name)
I get some results. Stupid of me to test a folder with wholly atypical contents
More later!
*I know some will wonder why I take flat file backups of VM’s. It’s because I’m paranoid OK? I copy them to external USB/FireWire drives for complete recoverability. It’s not like I do it every day or anything

What are #HP support returns smoking?
So today we are expecting the replacement which will, amongst other things, provide the returns packaging.
So I why, I wonder, did HP support email at 9:41 this morning complaining that the failed disk had not yet been returned? Their own call records should show that delivery is scheduled sometime today.
So soon after the TouchPad debacle, strategy changes, et al; HP's reputation at Corylus Towers is falling more rapidly than TouchPad stocks.
