• Difficulty moving the computer virtual to another Cluster with script

  I'm trying to consolidate the 2 groups one and decommision the old cluster.  Here's a piece of my script, and I get an error message.

  SE connect-VIServer vcenter-Credential $ADCreds

  $vms = get-Cluster $Cluster1, $Cluster2 | Get - VM | Select name
  $vms | {foreach-object
  Move-VM - VM $_. Name: Destination $Cluster3-confirm: $false - RunAsync
  }
  VIServer disconnect

  Here is the error.

  Move-VM: 22/08/2011-10:38:39 Move-VM you have specified a Cluster as a destination, but the virtual machine that you want to move is not in this Cluster. Select a host to destination in this Cluster.
  Online: 4 char: 11

  Could someone please shed some light on this issue.  I know this is possible because I saw basically the same Move-VM command in this forum as a work order for others.  I know that I can do what I'm trying to do because I've migrated a simple VM through the client to the new cluster without any problem at all.

  I can confirm that there is indeed a bug when you use a cluster as a destination.

  You can try with the RelocateVM method?

  $vm = Get-VM MyVN
  $clus = Get-Cluster MyCluster
  
  $pool = Get-ResourcePool -Name Resources -Location $clus
  
  $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec $spec.pool = $pool.Extensiondata.MoRef

• Understand the RDM?

  Hello

  I just post because I have trouble understanding the principle and operation of the RDM

  Car if I understand it, this is a mapping of a normal linked storage OUTDOOR unit a file to the local drive of the ESX VMFS?

  Question but my large, l ' unit OUTSIDE of storage Mapper en RDM must it be l ' ext3 or NTFS?

  Thanks in advance

  The file system of the RDM depand of your guest operating system disk, view what you not normal a vmdk, all of the volume of your disk file is normal view your VM and is formatted by it. This mainly allows to make under Microsoft cluster with nodes located different ESX 2 or allow the possibility of recovered data from an old server or on the contrary of "be able to participate on a physical server data."

• understand the average physics to share the virtual disk

  Hello

  I wanted to understand the physical way to share a virtual disk by configuring the scsi controller.

  

  As you can see in the image as an attachment, I chose the option - "physical - virtual disks can be shared between virtual machines on a server any."

  So, I have a scenario and please let me know if the above applies or not?

  I have 2 ESX host. I have created a virtual machine on ESX host1 and now I want the virtual disk of the virtual machine to be shared and eventually used by the virtual machine on the other ESX host2. can I use the option above to satisfy my need?

  Also on a special note, 2 ESX hosts are not on the shared storage. they run with their own local disk.

  Still, I'll be able to do what I want?

  Thanks in advance.

  No storage shared or using the storage equipment. The 2nd esxi host does not see the local storage on the original host.

  Discover will have on the creation of a Cluster of Mirosft see how you can share disks. You can create a cluster in a box on the same host or use of RDM with shared storage to allow multiple vm' hosts aces acros the same storage.

• How to install DSO on the shared cluster no

  I am trying to build Oracle RAC on the shared cluster No.
  The cluster has multiple nodes and each node has a disc. (normal shared nothing cluster)
  
  Before you install Oracle Database and RAC, I tried to install Oracle Grid Infrastructure
  based on the guide. < http://www.oracle.com/pls/db112/portal.portal_db?selected=11 >
  As you know, Oracle Database is a shared disk architecture, so I want to create a (virtual) shared disk to ASM,
  but I don't really understand how.
  
  The Oracle Grid Infrastructure installation program has a node in defining, but only looking at disks on the node of the installer.
  Also, seems that Setup installs only one instance of AMS on the Installer node.
  What I want to do is install on each node of the ASM instance and connect them to create a shared disk.
  Is it possible to do so by the installer?
  Or is it possible to do it manually?
  I'll be very appreciated if someone gives me guides to follow to get there.
  
  Thanks in advance.

  Oracle RAC can run on a distributed as lustre file system?

  Yes. But not recommended.

  I first thought that OCFS is a file system distributed as gloss as aggreates local disks on a shared nothing cluster and create a virtual view of the disks but it is fake, right?

  Yes. OCFS is used on a shared cluster storage (scsi devices seen by all nodes in the cluster) to present as a cooked file system storage. Not recommended to use Oracle RAC.

  Oracle RAC is a single physical database, residing on the shared storage. Each cluster node has an instance of database engine that rises and opens this same database. Interconnection allows you to basically share the memory of these nodes (share data in memory cache and communicate with each other).

  The end result is a commune-all the cluster. The complete database is available on each node in the cluster.

  The key components for CARS are the interconnection and the shared storage.

  The recommended interface is Infiniband (QDR/40 GB) - or, failing that, GigEthernet (10 GB). Low latency is critical for performance as cluster logical I/O is done essentially in this infrastructure, and it must be much faster than the physical i/o over the layer of fabric I/O. In other words, it's the kind of stupid to use 1 Gb Ethernet for interconnection and then channels shared double fiber 2 GB by access to the storage node.

  Shared storage is the next component. The most common is to a storage array that provides the fiber channel connectivity (e.g., EMC and others). HBA (double fiber ports) cards are installed per server and connected to the switch of storage host. LUNs are published for these HBAs and all the server nodes can see the same set of table storare lun. MPIO (assuming that Linux) is used to deal with the multiple paths of I/O (via dual fiber channel ports) to the LUN.

  Another option is Infiniband connectivity and use the SRP Protocol (Scsi access remote direct memory access Protocol). Exactly looks the same conceptually than the fibre channel option, but simply travels Infiniband. Fibre channel is currently at close to 8 Gbps max I think. InfiniBand QDR (Quad Data Rate) provides 40 Gb/s. It is also what produces RAC Oracle h/w called Exadata Database Machine uses (the fastest CARS currently available h/s).

  Other options use iSCSI for example - storage over Ethernet. But this requires at least 10 GB GigE a private network dedicated to your layer of fabric I/O. If you think that any decent kind of performance from him.

  Then come the R & D. virtualization approaches - run 2 virtual machines on the same hardware and provide storage shared for these virtual machines (you can for example provide access to systems of comments directly to the device host system scsi drives gross). Or you can use Firewire 800 and a 1 TB drive wire to both RAC nodes firewire, the Firewire shared storage drive.

  Performance and robustness of oracle RAC are directly related to the architecture of interconnection and the shared storage. So if you are planning to hack which (such as the use of a system of files distributed like chandelier), don't wait not performance or a robust CARS. Or Oracle Support.

• Untrusted connection is missing section "I understand the risks".

  Run Firefox 33.1.1 on Windows 7, try to access https://code.google.com. I get the page "this connection is untrusted", (specifically sec_error_unknown_issuer), but there is no section "I understand the risks" to allow me to add an exception. Other posts have suggested trying to 'forget this page', who has not solved the problem, or "Ce Frame: Open image in New Tab", which does not appear on right-click in this case. I also tried to go in 'View Page Info' but there was nothing out there for me to add the certificate either.

• Warning about bad connections contains no option "I understand the risks", I can't move on

  I install Thunderbird on Windows 8.1. I am trying to add 3 accounts. When adding the second account that Thunderbird has warned by transmitting unsecured password. I clicked on "I understand the risks". No problem. When I tried to add my third account, I received the warning again, but this time there was no other choice, "I understand the risks". I can't click on 'Done', if I change the parameter that TB can not find servers. I'm stuck and unable to add my last story.

  I installed on my laptop that runs Windows 7 TB and had no problems. I use the same settings as in my version of TB on my laptop. The version of TB is 24.4 on both machines. Of course, the version of TB was younger, when I installed on the laptop.

  Thank you, in advance, for any advice.

  If I wanted to get the certificate warning when connecting to my email provider's e-mail server, I would like to seriously check the offered certificate. There should be no exceptions to this need in the first place.

  Certificates are there for a purpose, and is not simply to add an exception when it does not work.

• "I understand the risks" missing option - page is read from cache

  trying to access the Web site, I am facing a security warning because the certificate is self-signed.
  This is an internal site, which is currently the subject of tests - so it's ok to add an exception.
  the question is, the option to select "I understand the risks" is totally absent, the only available action is "get me out of here"

  Since it is an internal site under our control, I did a few tests more:
  It seems that firefox redirects the initial http request to https
  This does not happen on other browsers (chrome and IE), also tested in a clean install of firefox running without the extensions.

  even after completely cleaning the cache and temporary files, question remains.
  This site (over http) does not load on firefox, always redirected to https

  even after deleting the server mod_ssl apache and by eliminating completely any mention of the ssl on that server, connection with firefox always redirects http to https (now results in the error "Unable to connect to Server" - but still not to load the basic site http version)

• I do understand the benefit of "Options" tab utilities and want to remove it. How, please?

  I do understand the benefit of "Options" tab utilities and want to remove it. How, please? I tried this feature because the tab 'Fox' was no longer available with the 5.0 update.

  I loved tab 'Fox '. A click and go on a site added you to 'top sites' before. The update 5.0, this feature is no longer available. It was a disappointment. There is a similar feature "add on" that is, as tab 'Fox' compatible with 5.0. If yes I would like to know about it. Or better yet... make it usable with Firefox 5.0 ' Fox' tab if upgrades cancel features previously downloaded that work really... What's the point?

  Please click the button solved it next to the answer that solved your problem of Firefox support, it appears when you are connected, so this thread is marked as resolved to help other users who may have this same problem.

• Difficult to understand the name of netbooks Toshiba

  It is difficult to understand the designation of toshiba netbooks for beginners is this prefix after etc. 500 550 nb-113 110 tell us about the battery? What is the best?

  Thank you and sorry for the bad English. What battery keeps arround 10 hours? Why NB305 (money) is more expensive than 500?

  Each Toshiba laptop inside has Toshiba label with basic information.
  It is written to the first name of the model: for example NB500-113
  Then you can see the number of pat s notebook: for this Satellite is PLL50E-xxxxxxx.

  Generally two numbers don t say much but for your info:
  The model name is depending on the country. For example, NB500-113 may be available only in Germany, but you won't find it in Spain. In Spain we NB500 - 22H. If the two laptops have the same reference number that designates two of them have identical hardware platform with identical inside hardware components.

  Toshiba NB500 offers three different numbers - PLL50E, PLL60E and PLL5ZE. With other words, you can buy NB500 with three different technical facilities. It is also possible that one of them will be offered in your country. It is defined by Toshiba s marketing strategy.

  What you need is good info on models available in your country. Please visit the support page of Toshiba for your country http://pc-support.toshiba-europe.com/ and option computers laptops & Netbooks.
  Compare all available models and look for info on equipment and the battery.

  I hope you now understand how it works. :)

• Understand the status icons

  I am struggling with the basics of Skype status symbols and understand what they restrict others to see, and can I be assuming that others can't see, with a host of other variables worthy of consideration when communicating with this program.

  One of the reasons is for example, the automatic switch of status for online, if someone has so much that even shifted they are mice. If a contact calls me, that I'd rather not talk with at the moment, and I refuse to answer, is there something I can do without wanting it, allowing them to know as?
  Without understanding the details of each parameter, it helps to talk to seems to me

  akin to play chess without knowing what can do the Queen.

• Do not understand the point of layout mode...

  I'm afraid it will make me look like an idiot, but... I just don't, so well, I'm missing something.

  Here's my situation: I have two USB MIDI devices connected to my computer, an edrum with 8 pads and a keyboard 25 keys, touch 16 and a bunch of buttons. Both devices allow me to completely configure the MIDI channel, note, the key pads, etc. and so on.

  So, ok, in my APPLICATION I plug just those, create a track for each instrument, I want to play, say each track to listen to a particular channel for a particular instrument, and I'm all set. The keys on the keyboard go to the channel where the synth plugin is listening, keyboard on another channel where a sampler is listening, and keys edrum go to a third channel where Superior Drummer is listening, etc. My edrums me has even let press a button to change between "kits", altering what channel/notes sends each pad, so I can load up, say, multiple instances of Superior Drummer and switch between them on the fly. Large.

  MainStage has much latency better than my DAW, so I'm trying to switch, but after searching around here, and by reading the manual (where the "Connecting MIDI instruments" section is literally just a diagram showing how to connect a MIDI cable and nothing else), I still feel stuck. It seems that I have to start by loading a concert (either drums or keyboards, but not two and no option for a clean slate), then shove a virtual representation of one of my instruments has not been included in the concert I have loaded and then link each individual pad notes not only a unit, not just a channel, but a specific (ditto the high/low notes on the keyboard).

  Why am associating notes with pictures of the pads when the whole point is that the notes are generated by the real thing?

  Why can't just say 'send some signals come from channel 1 device edrum to this plugin', and so on?

  Why am I spent the time to mount images of a keyboard and 24 portions on my screen (surprisingly difficult) when all I care gets ratings generated by a physical device to sounds generated by a plugin?

  Why this strange intermediaries?

  I know that mainstage is very well regarded by people who know more about this kind of things I do, so what I'm missing here? If I use the wrong tool for what I want to do, any suggestions for what I should try instead?

  If I understand the situation, all you really need to do is get rid of any control layout, you don't want, create the MIDI activity 2 monitors (1 for the keyboard, the other the drumpads), assign entries noon then label 2 devices for clarity.

  In edit mode, just do as you describe: assign one controls the activity of MIDI to a particular slice.
