vCOPs Custom Dashboard

Hi all,

 

first off hello, I am new to the field of VMware in a  corporate environment.

 

I have been experimenting with custom dashboards and have come up with some okay results, health and workload of the DC, scorecards to show remaining capacity in LUNS and so forth.

 

However I am a bit stuck and was wondering if anyone can help?

 

I was trying to design a scorecard that gives a count of what a DC contains, such as Clusters, Datastores, ESXI Hosts and VMs. As with all things that look simple it doesnt seem to be and i am scratching my head.

 

We are on vCOPs Version 5.7.0 Build 1073531 and the licence mode is advanced.

 

Thanks in advance for any help.

Fusion 6/6.0.1 and Mavericks Developer Preview 4 - Installer not creating Recovery partition

September 25, 2013, 9:00 am

I cannot seem to get a new install of Mavericks using the latest available full download from the Mac App Store (DP 4), to create a recovery partition during installation. I always end up with just an EFI and primary boot partition. The recovery partition is required to test new FileVault 2 features. Has anyone else seen this and/or found a solution? I filed a bug with Apple, but I feel like this is more of a VMware bug as the same installer on a physical machine did in fact create a recovery partition. I tried changing the hard drive type of the VM from SATA to SCSI, but that didn't make a difference.

 

Thanks,

- Mike

Peter,

 

Perhaps. I'll will give it a try. Though my problem is a change in VMware Tools, not the VMware View Agent. I'm using the same version of the VMware View Agent, and am instead upgrading to a newer version of VMware Tools to match the recently-patched ESXi hosts. I uninstall the View Agent, upgrade to the newer VMware Tools, and then re-install the exact same View Agent.

 

I do appreciate the KB and will research to see if it helps. Thank you.

As an example you can add the following options to the .vmx configuration file to set the Boot Order of the HDD.

 

bios.bootOrder = "HDD"

bios.hddOrder = "scsi0:0"

What are the differences in scale-ability and performance between the vCO appliance and a vCO Standalone server? I was able to find documentation on the standalone server, but did not see any documentation on the ova appliance. if anyone could point me to some specs on the ova appliance I would greatly appreciate it.

 

thank you,

Re: Reboot an UEFI VM with SATA CD/DVD

Here, we successfully launch a bootloader from the SATA CD/DVD:

 

2013-09-25T12:46:31.813+02:00| vcpu-0| I120: Guest: About to do EFI boot: EFI VMware Virtual SATA CDROM Drive (0.0)

 

... and it boots into an OS:

 

2013-09-25T12:46:36.804+02:00| vcpu-1| I120: CPU reset: soft (mode 2)

2013-09-25T12:46:36.815+02:00| vcpu-2| I120: CPU reset: soft (mode 2)

2013-09-25T12:46:36.827+02:00| vcpu-3| I120: CPU reset: soft (mode 2)

2013-09-25T12:46:36.838+02:00| vcpu-4| I120: CPU reset: soft (mode 2)

2013-09-25T12:46:36.849+02:00| vcpu-5| I120: CPU reset: soft (mode 2)

2013-09-25T12:46:36.861+02:00| vcpu-6| I120: CPU reset: soft (mode 2)

2013-09-25T12:46:36.872+02:00| vcpu-7| I120: CPU reset: soft (mode 2)

 

which runs for about two minutes before ejecting the disc...

 

2013-09-25T12:48:24.894+02:00| vmx| I120: CDROM: Guest eject on sata0:0. Disconnecting disc image.

2013-09-25T12:48:24.897+02:00| vmx| I120: CDROM: Disconnected cdrom: sata0:0

 

Three seconds after that, it reboots:

 

2013-09-25T12:48:27.440+02:00| vcpu-0| I120: CPU reset: soft (mode 1)

[...]

2013-09-25T12:48:27.466+02:00| vcpu-0| I120: Guest: EFI ROM version: VMW71.00V.0.B64.1308231723 (64-bit RELEASE)

 

... and we spend a few minutes searching for a boot device (skipping the EFI Shell), and then give up because we can't boot from an empty drive:

 

2013-09-25T12:49:43.438+02:00| vcpu-0| I120: Guest: EFI Shell inactive in default boot sequence.

2013-09-25T12:49:43.438+02:00| vcpu-0| I120: Msg_Post: Warning

2013-09-25T12:49:43.438+02:00| vcpu-0| I120: [msg.Backdoor.OsNotFound] No operating system was found. If you have an operating system installation disc, you can insert the disc into the system's CD-ROM drive and restart the virtual machine.

 

Do you know why the guest ejected the disc at 2013-09-25T12:48:24.894+02:00?  If you manually reinsert (reconnect) the disc again, does the VM boot properly?

 

Cheers,

Okay, I understand.  Doesn't resolve anything, but saves a trip into the BIOS.

Try something like this, it will display all LUNs that are visible on more than 1 cluster

 

$lunTab=@{}

foreach($clusterinGet-Cluster){
  Get-VMHost-Location$cluster|Get-Datastore|
  where {$_.Type-eq"VMFS"-and$_.ExtensionData.Summary.MultipleHostAccess} |%{
    $_.ExtensionData.Info.Vmfs.Extent|%{
      $key=$_.DiskName
      if($lunTab.ContainsKey($key)){
        $lunTab.Item($_.DiskName) =$lunTab.Item($_.DiskName),$cluster.Name
      }
      else{
        $lunTab.Add($_.DiskName,($clusterList))
      }
    }
  }
}
$lunTab.GetEnumerator() |where {@($_.Value).Count-gt1} |

There was a logic flaw in the script.

I corrected the code above, please try again with the new version.

I suspect it might be an issue with the Get-VIObjectByVIView cmdlet.

Do you also get the error when you replace line 12 by

$ghd = Get-HardDisk -VM $VM

Design cluster with active\active Behaviour

Hi guys,

 

So, I need to think about something like a Metrocluster, active\active, without using EMC VPlex (or similar).

 

Is it possible to create something like "vSphere HA multisite (geographically dispersed cluster)"?

Using EMC VNX, EMC Recover Point and/or EMC MirrorView in the middle?

 

I need some lights here to guide me (if it's possible of course). For a "active/passive solution" I already use SRM.

 

All of this using vSphere 5.1 or 5.5

 

Best Regards,

 

Pedro Pereira

Re: Esxi 5.1 pci passthrough broken

Yes. It solves my problem. Of course I had to convert my Windows 8 VM installation from BIOS to EFI, but after that it is working with GPU & USB Passthrough. In ESXi 5.0 it works out-of-box with BIOS firmware, and with ESXi 5.1 USB controllers passthrough does not work anywhere.

Same here Gregorcy, that error comes up via web client. I have not tried the other guy's fix yet. I still would like to try Srinu's fix (replacing the dll which he will provide us with). Lets hang tight.

Re: Schoose among the IDE, SCSI and SATA controllers

The best choice most likely depends on the guest OS and the nature of the I/O workload, and with hosted products (Workstation and Fusion) could also possibly depend on the host hardware and the host OS's driver stack.  It would be difficult to provide any sort of general answer.

 

My best advice would be to find the answer experimentally: Run some performance tests using the guest OSes and workloads configured as you intend to run in the VMs.

I didn't suggest that it would and was providing it as an example.  Obviously the value of bios.hddOrder can be changed accordingly.

 

That said, I would never under any circumsatnces in a physical or virtual machine attach two disks that have Windows OSes installed, with both having the boot flag set, on the same BUS.  I've seen bad things happen and as a result in the physical realm I always would put it in a Firewire/USB enclosure and attach it once the System was up and running.  Or I'd boot using a Linux Live OS where it would by default mount the NTFS Volume Read Only.

Calculate the size of a delta.vmdk on disk

September 25, 2013, 9:29 am

I read the result

hexdump -C -s 28 -n 4 name-000001-delta.vmdk

0000001c  b3 41 20 00                                       |.A .|

 

and convert that value to decimal - multiply it with 512 and then get a value for the size of a delta.vmdk.
The result is between 0 and 32728 sectors too small.

 

The difference seems to depend only on the size of data that has been newly added to the delta - not in the absolute size of the delta or the nominal size of the basedisk.

 

As snapshots can be larger than they should be without producing errors this rough formula works for now - but it would still be nice if I had a way to predict the exact size on disk of a delta.
If vmware.logs are available I simply look it up - in case I know which snapshot belongs to which VM.

 

But in worst case I only have the header of the delta file to determine the space on disk - so my question is:

 

is it possible to calculate the absolute size on disk when all you have is the beginning of the file and a vague idea of the max size ?
