You have two options -
- Access the data as an Raw Device Mapping (RDM)
- Use the Microsoft iSCSI software drivers and access the LUN directly from the VM

Re: Backup Errors with backing up thin provisioned disks on ESXi 5.1
I too get this error with a customer setup. For a long time I suspected that 4 times the total backup (since ghetto doesn't remove the oldest backup until the newest is completed) was too much space for the destination, but that wasn't the case. I'm yet to find out whats causing this. Any pointers appreciated!

Re: MacOS Command-line syntax for OVFTool
WoodyZ nailed it! Thank you...
Just in case this helps others, I was not aware of the machine.vmx file. Further adding to my confusion, was using finder to view the files that were there. With machine.vmwarevm appearing in finder as a non-descript flat file (and being perplex about where the .vmdk file disappeared to), I assumed .vmx in the reference was a type used for ESX or another VMware product. Now that I know, I know!
It is also interesting that the find command (IE find / -name "*.vmx" - print) reports the contents of .vmwarevm "directories".
(It's always the smallest points that derail us.)

Re: Script to Generate IOPS Report
Wow, thank you very much! That was really helpful.
I plan on setting the minutes for 1440 to show me a daily report of MAX IOPS, is there a way to show the daily average IOPS as well on the next column over? Then export it to CSV, organize by average in decending format and send me an email every morning... Haha. I'm sure I'll be able to string together something using this very helpful script!

No internet in bridge on guest Linux - Can ping gateway
Hello all,
I've been searching high and low but I can't figure this out. I'm running VMware Player 5 with Debian 7 64-bit as guest OS and Windows 7 64-bit as host.
I can access the internet using NAT but I would like to have connect to it as bridge.
I only see the one network adapter in Configure Adapters and it's the correct one, the one I'm using to connect to the internet. I confirmed that the adapter has bridge protocol enabled. I tried checking the "Replicate physical network connection" box but it did nothing.
What I can do:
I can see the VM from my router and assign it a local ip without issues.
I can SSH into the guest OS (Debian).
I can ping the host (my Win 7 machine) and the router (DNS/Gateway)
I can do nslookup (ex. nslookup google.com)
What I can't do:
I cannot access the internet. I can't ping google.com (by name or IP) or download packages.
Please help.

Progressively degrading data transfer speed - losing my mind!
We are attempting to migrate a bloated 1.5TB Win2k3 VM from
one SAN to another so that we can do some capitol maintenance and
reconfiguration work on the SAN that is currently holding this VM. It being a
long weekend, I thought it would be the perfect time to undertake this project
but I am having major problems with transfer speeds starting out fast and then slowly
nose-diving into the ridiculous. I have been reading posts and articles all
night and I just can’t figure out WTF.
The setup:
Host Server is a Dell PowerEdge 2900 attached via Dual iSCSI
link to a Dell MD 3000i – high-end SAN packed with 15k RPM SAS drives with
RAID.
VMWare version is ESXi 4.0 Enterprise Budle
Virtual Machine in question is Win2k3 (not that it matters)
Destination is either a directly-network-attached 1Gbps Linux
NAS packed with a proper RAID controller and 6G SATA drives.
Another destination that I tried is the host server’s internal
15k SAS disks on its onboard array.
The problem is that no matter what method of moving this VM
I try, the data transfer rate starts out AWESOME, at 95MB/Sec or higher, but
over the course of an hour or so slows down to a crawl – 10MB/Sec or even
slower. Looking at the data transfer rates on the disk read/write or on the
NICs, the drop follows a smooth downward arc. The symptom is the same whether
we attempt to perform a backup job from within the VM’s OS, or whether we try
to “Clone” from within the vSphere Console, or run a backup via VMWare Data
Recovery appliance interface. The sharpness
of the curve’s slowdown in transfer rate is different depending on the method,
but it happens nonetheless.
When running a backup from within the VM’s OS, the speed
drops slowly, starting out at 80MBps, down to 60MBps within an hour, down to
30MBps an hour after that and eventually levels out at about 8MBps for the rest
of the duration.
When we try to use the Clone function from within vSphere,
the job times out within 2 hours or so but the curve drop is quicker. It starts
out at 95MBps and within an hour is down to 10MBps or lower. I read a post and
found a place where I think I can extend the timeout period, but it seems
idiotic to me that I cannot just turn off the timeout altogether to let the job
finish.
Trying the VMWare Data recovery, the transfer speed drops
MUCH faster and much lower; it starts at about 50MBPS, but nose dives to under
1MB/sec within an hour. Leaving it running overnight, I finally canceled it as
it barely moved 50GB.
I have looked at everything that I can think of to explain
this, but everything looks normal – I cannot find the bottleneck or explain why
the speed drops off like this. I have shut off all other VMs on the system. I
have tried moving the target VM with it off. It seems to make no difference!
All systems – the host, the SAN and the NAS have plenty of resources and none
of them are getting hammered. I’m just at a loss to explain what’s going on.
I read an article about VAAI causing something very similar to
this, but after some research, it seems that VAAI support didn’t make it into
ESXi until version 4.1 and I am on 4.0. I tried to look for the VAAI controls
within vSphere and did not see them. However this MUST be some basic and
fundamental communications/buffer issue and I suspect (given that I have tried
moving the VM to two completely separate destinations) that the problem is
between the $8,000 host server and the $30,000 SAN. Ironically, my home-built
$1000 host server and $2000 SAN works perfect fine!
Suggestions welcome!

Re: Switches - best bang for the buck?
The fact you have dedicated switches for IP Storage and vMotion in my opinion makes Jumbo Frames more attractive, so that's one tick in the box.
Regarding your backups, by the sounds of it they are still agent based and therefor dependent on the network? This is something you should address as agent based backups (as you probably are aware) are a high impact to compute/network and storage and eliminating this overhead from your environment has numerous advantages.
For your W2k8 VMs, i would suggest upgrading them to VMXNET3 virtual nics as this will improve performance (where high transaction or throughput is required) and will allow you to custom set the MTU.
Here is an article explaining the various Virtual nic types.
However, if the processing is done on the VM and it does not have a dependency outside the VM itself, then I wouldn't expect the network performance for the VM (excluding for agent based backups) to improve with the VMXNET3 or Jumbo Frames as network traffic shouldn't be your bottleneck.
At the environment stands right now, I would investigate and confirm your not suffering any fragmentation, and if you are, lower the MTU until you can upgrade your switches.
You should also ensure the switches you buy meet your requirements and to do this, you should document your desired end state, and work backwards to ensure the new solution will achieve those goals. You also need to consider the fact your using 1GB, and how much more benefit you require from this upgrade. While its obviously more costly, moving to 10GB especially when using IP Storage (even when left on MTU1500) will give you a huge performance increase assuming your storage has 10GB ports.

So, I can´t use them without lost any file?

Re: esxi not recognize my hd with data
Not directly on the ESXi host - if you had shared storage and were able to add those disks to your shared storage you then would be able to present them as RDMs but this is not possible with Direct Attached Storage

Re: Backup Errors with backing up thin provisioned disks on ESXi 5.1
>However, when I start to create a backup, the process would terminate with an error :-(<
That is not correct. According to your post, you got to 66% before it terminated with an error.
I have the same problem. In my case, I make a separate virtual disk, and mount it with 2003 server to project an NFS volume. I use GhettoVCB, as you do. It uses the standard vkmfstools in the script to do the clone/backup. I've proven that the problem also happens when you use vkmfstools from the command line. GhettoVCB has a nasty habit of hiding from you the error code. The error code is that it ran out of disk space, which we both know didn't happen. Once the problem occurs, the only way I have been able to fix it is to delete the virtual disk, and start over, however, the problem will return. The problem didn't surface until I moved from ESXi 4.0 to 5.1 on the servers. Through this process, the hardware version off the VMs did not change, nor would I dare, since I may need to throw out 5.1 and move back to 4.x.

Re: No internet in bridge on guest Linux - Can ping gateway
Turns out it was my antivirus, Bitdefender Internet Security 2013, that was blocking the VM's connection.
To fix it I needed to set the network adapter VMware Player was bridging to as Trusted and Stealth mode off.

Hi!
I need to know if there is a link that says how to buy more licences for Mirage than the 10 you get from buying the suite.
I also need to know how to do the same for Workspace.
Any information is deeply appreciated
