    Thank you for the update markbenson. I'm marking this as resolved for now since it sounds like a future update will fix this.

    Need your guys' guidance on a DA/DR project I'm working on. From what I understand, there are 3 possible ways to create an offsite backup for VMware: Replication/HA, Stretched Cluster, and Site Recovery Manager (too expensive for us). Any advice on which one is better for the situation described below?

     

     

    2 sites with 3 hosts at each location: (2) R630's and (1) PowerVault SAN)

    - Each site has identical hardware/software/VMs, etc.

    - We don't have a lot of requirements, other than the recovery site needs to come up within a few minutes of the primary site going down. Saving money trumps ease of use & recovery time

    - We have a redundant 1GB/s L2 (possible 10 gig if needed) connection between both sites

     

     

    -If I went with Replication/HA, would I need another vCenter at site 2? If not, would I just use the vSphere client to manage the VMs at the recovery site temporarily?

    -Will I need to buy & install additional ESXi on the recovery site hosts for both Replication/HA and Stretched Cluster methods?

    -Which one is easier to initially setup?

    -Will I need vSAN?

    -And lastly, do I need to buy an OS (Win Server 2016) for each logical processor to run ESXi on?

     

    Thanks guys

    did you really just mark your own answer as helpful and correct even tough it was suggested by me and RajeevVCP4 to do exactly that?

    you have no idea how this community works, do you? but i'm happy your problem was solved.

    Have you looked at a third party solution such as Zerto or Veeam? If you need a low RPO, then Zerto is probably your best option. I replicate cross country with sub 1 minute RPO.

    When I create every new VM for general purpose Apps (often not known HW geometry previously), I'm ask myself - how many vCPU should I create and how it must be balanced - more to sockets or to cores? And would scaling vCPU counts may take worse for VM working? Finaly, _what happening_ w/ guest's OS and apps - when I do it. I think it is not exact, like when we set second/third-fourth CPU to HW server in empty slot, or change CPU's (physical) w 6 cores to modern 8/12 etc.

     

     

    So I have couple questions set:

     

     

    Firstly:

    so f.e. (from one hands) should I create 2 vCPU -s better 2 sockets and 1 core per socket, or 1 socket w/ 2 cores. Or maybe better way make all of them in full set.

    From other hands, I was told on courses VMFT 5.5 that many vCPUs in rare case better than few of them (2-4), and more  in count of sets it maybe worse. So better way make 1-2 vCPU.

     

     

    Secondly:

    is well known OS-s (f.e. Windows Server 2008-2016, linux ubuntu /redhat 5-7, freebsd) sense vCPU's on setup, or works worse when I scale vCPU-s instead when i give them final set of vCPU? So maybe I should create VM w/ 4 vCPU instead 1 or 2 as minimum. And, secondly, is a different w/ starting 1 vCPU vs 2 vCPU.

    Also to Apps, is common purposed Apps sense that scaling? I mean such apps as windows services (WSUS, AD) or mail systems (windows exchange or linux sendmail/postfix) or webservices (Firefront, apache/tomcat). Also and more interest RDBMS apps: MS SQL, Oracle database (standalone/RAC), MySQL.

     

     

    P.s.: I did scale few times and didnt noticed smth especial w/ VM guest and apps internal. I didnt noted those events and didnt inspect VM health after that.

    But a question is ...

     

     

    TY.

    Dev team wants SSL to terminate at the NSX LB and then to initiate another

    SSL session from LB to the pool servers at 8443. In the past I've used

    passthrough and my first attempt is giving me a

    502 Bad Gateway

    The server returned an invalid or incomplete response. 

     

    Do I need to configure "Pool Side SSL" in the application profile used by the VIP?

    Any other tips for 443 to the VIP and 8443 on the back end?

     

    Thank you!

  • 06/21/17--11:51: Re: Jumbo frame questions
  • As per my understanding , jumbo frames should be enabled end to end to avoid packet drops also it causes bottlenecks

     

    consider you have a server and end point. Server has MTU 1500 and all other devices (switched till end point has MTU 9000) , when a packet sent from endpoint with size greater than 1500 to server , since server supports only MTU 1500, the packet gets dropped vice versa won't be an issue.

     

    so , its generally suggested to have jumbo frames enabled end to end so that there wont be any packet drops.

    Hi Jeremyb,

     

    Did you resolve this issue? I am getting the same errors. Using VDDK 5.5.0 U2 to connect ESXi 6.5.

     

    Thanks in Advance.

    If you have a VM that's managed by SRM and you change it's CPU count or amount of memory does it automatically update the vmx file on the site where it will be brought up if it fails?  Or do you have to manually update it?

     

    Thanks,

     

    Pete

    BenFB - Thanks for the information on this. Your detailed contribution here helped us to be able to reproduce the issue. If .pfx/.p12 upload fails in this way, one of the workarounds will be needed until the next UAG version. PEM files supported in all versions remains a fully supported and working option.

    PowerCLI would work great, especially if you use the Import-CSV command with files already populated with the ESXi hosts and NFS datastores.

     

    nfs-datastores.txt - Datastores to map.

    vmhosts.nfs - ESXi hosts to map datastores to.

     

    Connect-VIServer -Server vcenter01
    $dsin = Import-CSV nfs-datastores.txt
    
    $hosts = Import-CSV vmhosts.nfs
    
    foreach ($vmhost in $hosts){
     write-host Doing $vmhost.vmHost
     foreach ($ds in $dsin){
    
        $x = Get-VMHost -Name $vmhost.vmHost | New-Datastore -NFS -Path $ds.NfsPath -NfsHost $ds.NfsHost -Name $ds.NfsName    write-host $x     }
    }

    What about hard drive? A fast SSD usually helps a lot.

    I am doing something like this and it appears to be working the way that I have expected.  First thing, in your blueprint make sure the approval policy value is blank.

     

    Now I have a subscription that fires at VMPSMasterWorkflow32.Requested/PRE.  This subscription handles all the data processing that I did not need to do in the form and updates a bunch of values in the process.

     

    Below is the code from the subscription for the reservation piece:  I have a location value that is made up of different values and I split that value into an array to work with

     

    The value that I return is __ReservationPolicyID

     

    var locs = location.split(" ");

    if ( locs[2] != "Online" ){locs[2] = "dataCanter"};

    //var blueprint = System.getContext().getParameter("__asd_composition_blueprintId");

    //var component = System.getContext().getParameter("__asd_composition_componentId");

    var blueprint = bluePrintID;

    var component = ComponentId;

    var user = System.getContext().getParameter("__asd_requestedFor");

    var tenant = System.getContext().getParameter("__asd_tenantRef");

     

    var host = vCACCAFEHostManager.getDefaultHostForTenant(tenant , true);

    var reservationPolicyService = host.createReservationClient().getReservationReservationPolicyService();

     

    var reservations = System.getModule("com.vmware.vra.reservations").getReservationsForUserAndComponent(user,tenant,host, blueprint, component);

     

    // get reservation filtered by reservations

     

    var reservationPolicyFilter = getReservationPolicyFilterForReservations(reservations);

    var reservationPolicies = [];

    if (reservationPolicyFilter) {

                   reservationPolicies = reservationPolicyService.getAllReservationPolicies(reservationPolicyFilter).getContent();

    }

     

    //System.log("looking for policy with name " + locs[1] + "-" + locs[2]+ "-" + osType);

    var reservationPolicyProperties = new Properties();

    for each(var reservationPolicy in reservationPolicies) {

                   //if (reservationPolicy.getName().indexOf(locs[1]) >= 0){

                   //System.log(reservationPolicy.getName() + " / " + reservationPolicy.name);

                   if (reservationPolicy.name = locs[0] + "-" + locs[2]+ "-" + osType){

                                  reservationPolicyProperties.put(reservationPolicy.id, reservationPolicy.name);

                                  var ReservationPolicyID = reservationPolicy.id.toString();

                                  var policyReservation = reservationPolicy

                                  }

    }

     

    //////////////////////////////////////////////////////////////////////////////////////////////////////////

    function getReservationPolicyFilterForReservations(reservations) {

                   var query = new vCACCAFEOdataQuery();

     

                   var queryParams = [];

                   for each (var reservation in reservations) {

                                  queryParams.push(vCACCAFEFilterParam.equal("id" , vCACCAFEFilterParam.string(reservation.getReservationPolicyId())));

                   }

     

                   if(queryParams.length > 1) {

                                  query.addFilter([vCACCAFEFilterParam.or(queryParams)]);

                   } else if(queryParams.length == 1){

                                  query.addFilter(queryParams);

                   } else {

                                  return null;

                   }

                 

                   return new vCACCAFEPageOdataRequest(1 , 2147483647, query);

    }

     

     

    //---------------------------------------------------------------------------------------->

     

    Since we are talking about reservation Policies and reservations in general this might be worth sharing.  I actual pull the available networks from the reservation itself and use this code as the property action:

    Thanks markbenson, we are doing the later where we enter the AD username and password and the RADIUS server handles the workflow to do a device push for MFA. If that times out then the user is prompted to enter a passcode that is generated from the app installed on their device. I have the team that manages the RADIUS server looking at our options to respond with a Access-Accept instead of Access-Reject when the AD password is expired.

     

    One of the early engineers on the case suggested shifting RADIUS from the UAG to the connection server. The thought was that if the UAG is configured to only do pass-through authentication it would offload that to the connection server and then the connection server would enforce RADIUS. It sounds like we would have the same issue doing that as well?

    In 5.5 we had both the Syslog Collector and Dump Collector installer.  In 6.5 we don't have that any longer.  It appears that you can configure your VCSA, PSC, and ESX Hosts to use a syslog collector for logs and a shared diagnostic partition for dumps.  But there's no installer to setup a collector is that correct?  Is VMware trying to encourage buying Log Insight to collect the logs?

     

    Thanks

  • 06/21/17--12:40: Re: Raw Device Mappings
  • I think it will be deleted, because the RAW disk needs to be formated

    No, not at all. A Raw Device - i.e. the storage LUN itself - will not be touched, or modified by the Hypervisor (ESXi).

    With creating an RDM, ESXi only creates a .vmdk mapping file which point to this LUN. The file system, and the data on that LUN are exactly the same, no matter whether the LUN is presented to a physical server, or as an RDM to a VM.

     

    The only thing you need to ensure, is that the storage system is supported for the ESXi version you are going to use.

     

    André

     

    PS: Please ensure that the LUNs are presented to only one Windows OS (physical or virtual) at the same time to avoid possible data corruption!
