• CRIO several in the same project

  Hi all

  I work in a project that has the CRIO several but they all have the same code. Then... I have a project which include the CRIO. So far, I only worked by one. Yesterday, I create the new target CRIO and dragged the main code that him. When I saw the code, I discovered that it was necessary to recreate a link to FPGA code. Ok... Not a lot of work on this! But after that, all the Subvi become in error state saying that the FPGA reference type was incorrect.

  It is a scary idea, because the system wil consume a large number of CRIOS (maybe 10 or more) and when I change the code that I need a quick way to freshen up the whole system.

  Can someone help me on this?

  Hello and thank you for your well after!

  For now I think that my problem is solutioned your pointing to the 'bitfile' failure and using the name of the resource.

  I'll do some tests over to check if it's ok. But it looks good!

  Thanks again!

• Deploy multiple virtual machines on several hosts evenly?

  Hello people!

  I wrote a small script to deploy many virtual machines on several hosts at random.

  But I would rather deploy a virtual machine to each host in a table and then start over again until the number of virtual machines to deploy exhausted.  Distribution of the burden of deployment as evenly as possible.

  Anyone have a suggestion?  Example of nested loops?

  

  PowerShell beginner, here.

  Thank you

  One way to do this is with the modulo operator (%), something like this

  $numVMs = 11

  $tgtEsx = get-Cluster "Westcreek | Get-VMHost-name z420 *.

  1.. $numVMs | %{

  [New-VM-name 'Test $($_)' $tgtEsx[$_%$tgtEsx.Count - VMHost]

  }

• Deploying the cRIO controller host VI

  When I include a Variable Shared Network-Published in my host VI, VI wants to deploy on my cRIO.  Without the shared Variable Network-Published, it runs on the host as planned.

  Yes, the Sub host VI post work and VI RT is under the lens of the LabVIEW project.

  How to use a shared variable in a VI to run on the host computer?  I need to pass data between my RT VI running on the cRIO and a host VI running on a Windows host.

  Hello Shall12,

  I misinterpreted your posts original - this option should be changed to the target on which variables are deployed.  Based on your screenshot, the library is contained on the RIO and should be changed it.  The behavior you're seeing is described in more detail here:

• cRIO autorun host VI

  Hi, I am using a cRIO (9012 + 9102) with LV 8.5, build a project of QA control and data boarded for a hybrid race car.  I would like to be able to run this stand-alone without a connected PC.  I had my FPGA runs just fine on its own, download the bitfile, load automatically under tension and all that and the FPGA code runs fine without a connected computer.  Now I have a host VI on my controller, which stores the data on a USB key.  I am fighting to figure out how get the host VI runs automatically, just like the FPGA does, and I begin to feel that it is because you can not do this!

  I see in the host VI properties (right click on the host VI > properties) there is a category of execution, where I have the option to select "run opening.  It is great, but is there a setting somewhere 'open' the VI whenever the cRIO is turned on?  I have a digital built-in switch to turn recording on my USB on and outside, so I can stop writing about a file before deleting the key.

  Thanks for your help, I'm probably missing something pretty basic, but I've looked everywhere with all the keywords, I can think.

  The recommended way to create an application, which begins when a target time starting real LabVIEW, is to build in an executable and set it as start. You can do this by building the executable for the VI real time, right click on the VI and choose "set as startup" and deployment. But, you can now configure start screws as well although I think that it is much faster to create an executable file and the right way to do it:

  Startup configuration live on target time real LabVIEW
  Start screws vs executable startup on a real-time operating system

• several hosts aaa server for authentication vpn

  ASA5510 - 7.2 (1)

  Using the following configuration, I try to have several radius servers configured for authentication backup in case of failure of the primary vpn. This seems to work ok. But once the main server upward when the asa will begin to use it again. The release of "aaa-Server 172.25.4.20 host" said

  Server status: FAILURE, server disabled at 08:04:25.

  How do reactivate you it?

  RADIUS protocol AAA-server adauth

  adauth AAA-server 172.25.4.20

  key *.

  authentication port 1812

  accounting-port 1813

  adauth AAA-server 172.25.4.40

  key *.

  authentication port 1812

  accounting-port 1813

  tunnel-group group general attributes

  address pool pool

  authentication-server-group adauth

  by default-group-policy

  You can add the option in the Group aaa-server:

  "reactivation in timed mode.

  This causes a dead server is added to the pool after 30 seconds.

  The following link has some good info on the options available. I suggest looking for the doc for the "reactivation".

• Activation of the NAC HA puts several hosts and ASA with processor clocked at 100%

  I installed a NAC Manager and a NAC server in OOB without any problems, but when I configured the AP (high availability) with another server, my ASA and several guests in my network started work ant 100% of the cpu.

  I tried to configure each interface of the NAC on a single DMZ and the problem stops there.

• Configuration of the network with several hosts (dVS/EtherChannel)

  Hey,.

  Let's say that there are 4 hosts, each with 2 NETWORK adapter connected to a switch. On the side of ESX, all uplinks are added to a dVS and the port group is set to 'Route based on IP Hash'.

  Host 1 > change of ports 1 and 2

  Host 2 > change ports 3 and 4

  Host 3 > change ports 5 and 6

  Host 4 > change ports 7 and 8

  The switch (Cisco) must be configured as:

  Port channel 1: 1 to 8 Ports

  OR

  
  Port channel 1: 1 and 2 Ports

  Port channel 2: 3 and 4 Ports

  Port channel 3: Ports 5 and 6

  Port Channel 4: 7 and 8 Ports

  Thanks for any help.

  A port for each host channel... This article shows an example with two hosts: example configuration of EtherChannel / switches control protocol LACP (Link Aggregation) with ESXi/ESX and Cisco/HP (1004048)

• I would like to revive the officer on several hosts

  I would like to revive the MA on different hosts, using a file entry for host names.  Does anyone have something similar to this or can point me in the right direction please?

  Thank you

  I suspect that might be a problem

  When the ESXi is not connected to the vCenter, the Get-VMHostService may not work.

  IMHO, there are 2 alternatives

  1) connect to each ESXi host with the Connect-VICenter cmdlet and restart once connected to the service in the same way as I showed

  2) connect to the interface of the ILO.

  If I remember correctly there is a PowerShell library for this.

  But I don't know how you can use this to restart a service on the ESXi.

• VMotion between several hosts

  I have just joined a company that executes 2 guests on ESXi 4.1 Standard, and both hosts have 1 CPU.

  I have get a business license for the two hosts to allow storage vmotion, but would welcome that bumping the hosts up to 2xCPUs (with additional CPU licenses).

  If finance means that I can't upgrade the two hosts, for example, if you had 1xCPU and the other 2, vmotion would fail? If so, will create a VCA basic iron out this problem?

  Thank you

  Hello..

  vMoton should work just fine for a long time the CPU being identical acrosse the two hosts and ofc with good installed licenses.

  It doesn't matter if a host has only one and another two physical processors. (Ive got a mixed cluster here with some guests with 2xCPUs and some CPU 4 x)

  VCA troubleshoots only presenting sets of features identical CPU on all hosts as long they are in the same family... See more details here: http://kb.vmware.com/kb/1003212

• Basin balanced on several hosts (No. SAN)

  Im running 4.6.  I have a pool of composer view limited to one host running the local storage.  I'm the ability for this host.  My question is it possible to allocate a second host, using its local storage space, have the pool balanced between the two hosts.  I'm guessing that he should create a replica for each data store.  Is it possible to Setup?

  TIA

  Tony

  Just to test this point for you, I created a test tank my view cluster and two of the local data stores selected as storage device.   The virtual machine was deployed in two stores of data with no problems and you are right that there is a replica on each data store.

• several host esx on an iSCSI LUN?

  I use openfiler as my iSCSI target, and I just traced all the space available for a logic unit number with the intention to use it for the three ESX hosts.

  Can I share a LUN on multiple ESX hosts?

  (or, I have to create three LUNS... one per ESX host).

  The reason I want to do a logic unit number is so I can bring up a VM on another ESX host without adding storage or move the files of the virtual machine.

  It is supported and even necessary for things like vMotion, etc.. Just make sure you have your SAN configured to allow simultaneous access to the same target.

• Several Host Isolation

  Imagine a scenario where we had a HA of four nodes cluster spread on a campus with two nodes in one place and two in the other. What would the host isolation response if the network connection between the two sites has been lost?

  If we lose a host then the TI is known to be isolated after 12 years and then failed aftet 15s. If we lose two, however, nobody is isolated and I am assuming that nothing happens.

  Now; Imagine that we have warehouses of data which are all shared, but some are in one site and some are in the other. Guests running on local data warehouses would be unaffected. Guests who are running on data warehouses remote fails. The question is: what will happen to the hosts failed?

  Thank you

  Warren Barnes

  Before you answer this in detail, I want to make sure I'm clear on my assumptions:

  1. There are 4 hosts in the cluster, two on each side of the stretch. If this is the case, then all 4 hosts are primary. (The first 5 guests in any cluster are primary, so you get only secondary when there are 6 or more hosts).

  2 If the network fails between the two sites, storage will be split-brain as well? I guess that Yes, based on one of your comments.

  If, in view of the #1 site hosts A and B, and site #2 a hosts C a D...

  If, after the split between site 1 and 2, and B can still heart rhythm with each other, and C and D can pulse between them then there is no answer tried insulation. Answers insulation kick only in when a host can not with any of the other primitives of the heart rate, and it can also ping the address of isolation (usually the gateway (s)) for networks that host is on.

  So what happens is that A & B site 1 to conclude that C & D at site 2 have failed. And vice versa. A and B will try to power - on the virtual machines that are running on C and D, even for C & D - they will try and power on virtual machines that have been on A and b. Now, because the storage of some virtual machines can be found at site 1 and storage other virtual machines are at site 2, some of the power-ons may fail because the storage is not accessible. But as A & B will attempt to power on the set of the VMS C & D and C & D will attempt to power on the set of virtual machines of A & B (that means that admission control allows all of these power-ons) then each VM will end up under tension correctly on each site 1 or site 2.

  Now for the ugly part - if any of the VMS to site 1 lost their storage in the score, or vice versa, then the vmware-vmx process who represent these virtual machines always operate on one or more hosts on the side of the partition that has lost the storage and there is now a process vmware-vmx representative the same virtual machine running on a host across the partition that has now acquired a lock on this VM. None of this is a problem until the partition joined. This is so the behavior described by Elisha happens - that is to say the virtual machine appears to bounce back between the two hosts until the answer to the question on the lock lost by pointing the VC client directly to the host. And as he pointed out, the question will be auto-répondu by VC to vSphere 4.0 U2 and above.
