• VMware Paravirtual SCSI adapter

  Is there a reason the "VMware Paravirtual SCSI" is not to use it?

  I would use this adapter for each VM of data partitions (not partitions to boot).

  Reason: Have the hole identitical environment.

  I have only heard one drawback: VMs with e/s low will have no gain performance on the SCSI adapter which is usually used.

  Thanks for your review!

  Is there a reason the "VMware Paravirtual SCSI" is not to use it?

  If you do not need FT, I see no reason right now.

  See http://blog.scottlowe.org/2009/07/05/another-reason-not-to-use-pvscsi-or-vmxnet3/

  I would use this adapter for each VM of data partitions (not partitions to boot).

  I guess you know that, anyway.

  Reference Dell R710 Server

  I install WIN 2003 x 64 as a virtual server on ESX 4, when I select LSI logic SAS & LSI logic parallel it does not detect the hard drive, do I need driver if so where can I download?

  For parallel bus logic (not recommended for the guest operating system) & Vmware paravirtual, do I have to select this option for my win 2003 R2 x 64 edition?

  Please help on this issue.

  If you really want to use it for installation, you will need to extract the driver from the VMware Tools ISO and add it to a disk image.

• SCSI - LSI to VMWare Paravirtual conversion

  Has anyone out there converted from LSI to the Paravirtual on a production machine? It went smoothly?

  I have a Win2K8 R2 guest who lives on a 5.0 ESX host.  The guest is to serve a large number of LUNS via RDM.  Each of the LUNS is greater than 2 TB in size.  I ran into a bunch of related storage errors on the host.  Most of them were related to problems of journey with the backend and I worked with the storage vendor to solve those.

  The last numbers are now coming from LSI_SAS with the error, "restore the device, \Device\RaidPort2, has been issued.»

  The research that I did, the driver SCSI Paravirtual is supposed to help relieve the kind that I'll have performance problems.  My question is how the security is to convert the pilot on a production machine?

  My intention is to turn them off the prompt, change SCSI controller device in the comments settings and power and then turn.

  My concern is that the BONE will panic and not being able to see one of the disks.

  A further complication of the situation, is that there were a large number of ntfs.sys errors associated with a couple LUNS.  These LUNS must be chkdsk'd at the next reboot.  I am sure that ntfs.sys errors were generated by high latency problems with multiple paths of 90%.  These problems have been resolved.

  Well, the article is not very detailed. Here are the instructions:

  1. While the virtual machine is running, add a new drive with 1:0 SCSI ID (or 2:0 if 1:x already exists)
  2. This will also add a new SCSI controller. Before closing the dialog box change its pvscsi type.
  3 within the verification of the virtual machine with Disk Manager if the disc appears there (you may need to rescan or manually install the driver of pvscsi starting from the VMware Tools)
  4. when the disk appears pvscsi driver has been successfully added and activated.
  5. stop the virtual machine and remove the newly added disk (this will also remove the additional SCSI controller).
  6. change the type of the first SCSI pvscsi controller and power on the virtual machine again.

  Make sure you have scsi paravirtualized drivers installed on the client, otherwise it won't know how to join his drive.

  They are available in a disk image in the floppies/vmimages/directory on a host computer.

  Also, make sure that you meet the compatibility matrix as in this KB:

• Replace SCSI with PowerCLI paravirtual adapater

  Hi all

  I have people on my site that Canoe follow documentation, so I'm trying a little easier, but not having not much of chance.  After I install my servers ESX 1 update, I would like to automate the update of the comment tools and replace disk paravirtual cards.  The upgrade of the tools is easy because I see the cmdlet to do, but nobody knows how to determine the type of scsi adapter a virtual machine use and replace it with VMware paravirtual on Windows 2003 / 2008 Windows guests using powershell.

  Thank you

  Take a look at my script in the section failover to the Paravirtual SCSI controller.

• PvSCSI adapter for physical RDM expandable disk using?

  Hi all

  Can anyone here please indicate if the scenario below is supported for RDM physical disk with the extensible feature in the future?

  R2 Windows Server 2012

  Physical RDM: NTFS table partition GUID 2 TB which can be expandable to 12 TB + in the future

  SCSI controller: pvSCSI SCSI 1:1

  Because the KB article: VMware KB: configuration of disks to use VMware Paravirtual (PVSCSI) SCSI adapters says:

  • Do not use the PVSCSI on a virtual machine running Windows with split volumes. Data may become inaccessible to the guest operating system.

  
  

  Thank you

  If you use physical (amp) RDM, why would you use volumes split inside the guest?  You present a lun 12 to large or smaller and covering inside the guest OS?

• Performance problem with the guest operating system

  Hello gurus - I have one of the most unusual questions, I ran into a few time.   Here it is:

  I have a guest w2008R2 OS - installed in a 5.1 version of VM 7 vSpherer - which has an Emulex LPe 12002-E 8 GB dual HBA port is assigned to the as 2 PCI (1 device per port) via DirectPath devices

  The guest operating system has an application that performs backup tests.   WWPN of the HBA is zoned in the fabric and declared in the interface of Compellent Storage Center and everything is good here. the application creates a replay of a volume, mount it as a drive, read all the blocks, then dismantles and moves then repeat the process with what ever additional volumes should be safeguarded.   It is so cool I have do this with a VM right and not a physical host?  (would be cool if I had work NPIV but that's another story, not with technology HBA vendor support...)

  So, what's the problem?   Well, the bed the mounted disk backup will work extremely slow as slow as 5MB\sec flow, then during any other activity takes place on the system the flow jumps up to 150MB\sec all of a sudden and will continue to run fast for a long time and finish jobs on time with each work taking a little more than an hour.  But when the slow going the same work (all jobs are the same, they are simply by reading all the blocks of a bunch of 200 GB volumes and wrote a set of NULL value, do not forget this is just test) takes up to 10 hours to complete.

  I think that what is the culprit?   POWER MANAGEMENT.

  I have just about each performance counter and the journal of events known to man and I don't see anything abnormal on the table, ESXi virtual machine, nothing.  But what I see in the newspapers is any kind of activity that could happen in a transparent manner to save energy.

  FACTS on this case:

  -Reservation of memory is defined (it must be for directpath otherwise, you can't power on the virtual machine)

  -Booking CPU - has not been defined before an hour ago, I gave her just a small reserve for this rule, so I do not know if this will help alleviate the slow flow, or have an effect on what I think is a question of power (unit linked) management

  -windows power management is set to high performance never-ever - but not until an hour there doesn't I changed advanced settings for USB Disabled------turned off.  PCI peripheral energy saving setting was already off.  Which is in contradiction with my theory.  But maybe, just maybe, something is broken somewhere, or could be a bug... blah blah blah

  -the HBA, Emulex, as it appears in Device Manager in the guest OS doesn't have a power management tab to disable the feature, I don't see that the adapter VMXNET3 had this tab, and I turn off the power save setting to be conservative, do not think that it was the culprit, but as there is no real data running through the NIC.  The data is simply to be read from the disk mounted, not copied on any wire Ethernet.  never the less, in the Emulex properties is a Details tab and a selection of power data, and performance data indicate you what power mode, the device is, as well as feeding supported systems.  D0: full power, but D3, which shows as supported by the device, is an energy saving mode.   I could not yet attend the setting at the time of slow activity, my good intention as soon as possible. He is currently shooting in D0, full power.

  This is so what I have to offer on this, I hope that its just...   If I'm missing something, or if others have experienced this massive loss of unknown flow without reason and have resolutions, please share.

  If there is a way for me to disable power on the Emulex HBA management inform you please, I don't mind if I stop to enter the firmware, if that was even possible.  But if possible I would disable it immediately before any new tests are executed.

  The root cause of this issue has never been identified by VMware support which for me is a question of ugly.  Reservation of CPU for the VM using directpath IO with HBA installed in it corrected the problem.  I'd be leary with direct path IO.

• SCSI driver selectio VM version 7

  Hello

  I'm trying to find a consensus of the SCSI adapter to use, the operating system we have is Win2k3 WIn2k8 SP2, Win2k8 R2.

  For the system OS disk what is the SCSI driver that is recommended for this partition, I read some documents that mention;

  -drive system (Vmware Paravirtual) is not supported, so I guess that's out of the question for c:\ then to d:\ I assume that VMware paravirtual is recommended as it gives the best results.

  - but then for C:\ whats the recommended for Win2k3/wk8 'LSI logic SAS' or 'LSI Logic parallel' we do not use any Windows cluster or other simple stand-alone servers.

  -In addition to d:\ phsycial RDM I assume because I also use "Vmware Paravirtual" for better performance

  fix?

  In addition, once I changed my SCSI driver according to doco.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1010398

  How can I confirm OS, I use this driver for the disk D:\?

• Why do not the remove-hard drive remove a disc with a new SCSI controller?

  Hi PowerCLI gurus,

  I try to use PowerCLI to automate the solution for article configuration of disks to use VMware Paravirtual (PVSCSI) SCSI adapters (1010398).

  Remove-hard drive sometimes gives me a misleading error when I use it to remove a hard drive with a new SCSI controller.

  The FlatHardDisk specified 'Hard disk 3' no longer exists, or never existed.

  Can anyone here explain the error?

  My version of vCenter server is 5.1.0.

  My PowerCLI version is 2.0.

  Here's what I've done to reproduce the error.

  First of all, I connect to vCenter and stop the virtual machine.

  $TestVM = 'TESTVM '.

  $TestServer = ' vcenter - test.local ".

  SE connect-VIServer-Server $TestServer

  Stop-VM - $TestVM VM - confirm: $false

  I add a new hard drive and store it in a variable so I can refer to it for the next steps.

  New hard drive '.

  -VM $TestVM '

  -Persistent persistence"

  -Flat DiskType '

  CapacityKB - 1024'

  StorageFormat - thin '

  -OutVariable TempDisk

  I make a note of its name.

  $TempDisk.Name

  Because my VM already has 2 discs, the output is "hard drive 3.

  Then I add a new SCSI controller on the hard drive.

  New SCSI controller.

  Hard drive - $TempDisk '

  -Type ParaVirtual '

  NoSharing - BusSharingMode

  Now, I try to remove the hard drive from the variable to remove the disc.

  Remove-hard drive - hard drive $TempDisk - DeletePermanently-confirm: $false

  It fails with an error that says "Hard drive 3" has already been removed.

  Remove HDD: 12/02/2014-18:51:33 remove-hard drive the FlatHardDisk specified 'Hard disk 3' no longer exists, or never existed.

  On line: 1 char: 1

  + Delete-hard drive - hard drive $TempDisk - DeletePermanently-confirm: $false

  + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  + CategoryInfo: ObjectNotFound: (3:FlatHardDiskImpl drive) [Remove-hard drive], VimException

  + FullyQualifiedErrorId: Client20_VirtualDeviceServiceImpl_TryValidateDeviceExists_DeviceDoesNotExist, VMware.VimAutomation.ViCore.Cmdlets.Commands.RemoveHardDisk

  But I see that there are still "hard drive 3"!

  Get-disk hard - VM $TestVM - name 'hard drive 3.

  CapacityGB persistence Filename

  ----------      -----------                                    --------

  0.001 persist... B-DATA-01] TESTVM/TESTVM_9.vmdk

  Is this a bug or am I missing something?

  I don't think that the cmdlet uses actually the UID, but more likely a MoRef to the vSphere object that represents the hard disk.

  Remember that under the covers most of the PowerCLI cmdlets do calls to the vSphere API.

  Change the Uid, property value indicates that the hard drive connected to the new controller is a new and different purpose.

  And this explains why the hard drive remove does not work with the original hard disk object, it no longer exists.

• Reviews of R2 Server 2012 - PVSCSI.flp - missing drive

  Hey all,.

  I'm having a problem with the installation of Server R2 2012 in ESXi 5.5 U1. I am running in a SAN environment. The hosts are connected to the San. Any assistance with this would be very helpful!

  I created a new virtual machine with all the basic settings. These are the changes to the SCSI card.

  Controller SCSI - 0

  Type of controller SCSI- VMware Paravirtual

  SCSI Bus sharing - No

  Hard drive 1

  Disk file - < SAN map >

  Disk configuration - Thin Provisioning

  Provisioned size: 40 GB

  Virtual device node: SCSI (0:0) hard disk 1

  Independent mode - < disabled >

  Guest BIOS:

  "Primary Master" - [no]

  Windows Server 2012 R2 Standard

  Image of disk pvscsi.inf file is found and installed.

  No disks are found.

  This problem has been resolved. It's a corrupt ISO that has been downloaded. The pvscsi.inf is correctly loaded once a new image Server R2 2012 has been downloaded.

  Only way I found out was when I loaded ISO in VMware Fusion. He said that the client tried to access the image beyond the size of the image. Unfortunately, ESXI has not thrown any errors similar to the following.

• Hardware certification - Question of Type of SCSI controller

  Controller SCSI of VM types are defined in the Certification Guide of compulsory storage?

  I installed Windows 2008 Server on a virtual machine with the type of LSI Logic SAS controller (that I see, I can't change it prior to installation) and after that the installation has been completed and VM booted ok I put off and then changed the type of controller for VMware Paravirtual. VM could not start. I changed the type of controller to LSI Logic parallel and got the same result - VM could not start Windows.

  Can I use LSI Logic SAS on all virtual machines where I can not change the type of controller or it will not pass the verification test?

  Thank you in advance.

  The reason why it cannot start, it is that there is no driver installed for it.

  To work around this, add another controller of the new type, start windows and install the driver, then stop switch the premiera autour and you should be fine.

• Go to vCenter Update 5.1 1?

  Hi guys

  I want to move to vCenter device 5.1 U1, consult vmware site for download I see this

  VMware-vCenter-Server-Appliance-5.1.0.10000-1065184-updaterepo.iso

  Comment says:

  VMware vCenter Server 5.1.0 Update 1 device

  This package allows to update VMware vCenter Server Appliance 5.1.0a, 5.1.0b to VMware vCenter Server 5.1.0 Update 1 device.

  For now, I have multiple vCenters 2 different builds

  VCDOMC - Version 5.1 build 799731 - vCenter Server Appliance 5.1GA

  VCDCRR - Version 5.1 build 799731 - vCenter Server Appliance 5.1GA

  So what is the 5.1 GA release upgade path then?

  to what I see, I can spend my VCPAM but what about the 5.1 GA release vCenter devices.

  Thank you
