Error: Unable to power on Virtual Machine

I am unable to power on a VM on a production environment and the error received is:
 "No Host is compatible with the virtual Machine"

I migrated the  VM to another  Host in the cluster and then received the following error:
An error was received from the ESX host while powering on VM host xxxx.

We are using vSphere 5.1.

Event Details:  
Type ID: Info
Target Object Type: ClusterComputeResource
DataCenter Object Type: Datacenter
Host Object Type: HostSytem
Host Build: 838463
VM Object Type: Virtual Machine
ChainID: 3341944

Any idea how to fix this please.

Was the guest created on a different platform other than your production cluster? It could be a difference in virtual platform.

If problems persist, create a new VM and point it to the drives for the problem machine.

does it only occur with this VM or other VMs ?

have you changed anything on this VM, e.g. memory or CPUs ?

This is the status:

1. There is no additional space in SAN
2. Unable to  create a new VM and point it to the drives since Consolidation for this VM is going on to make some space
3. No changes have been made to CPU or memory
4. It is happening only to this VM

what is the storage free space on the LUN ?

is all the VM folder data?

did you know you have many snapshots on the VM ?
cgeorgeisaac

ASKER
1. Yes there were snapshot so we consolidated it.
2. When the consolidated took place it hung at 99%
3.  In the LUN - Capacity 1.46 TB and   Free 128 GB  (Type VMFS 5)
4. Yes the VM Folder is Data.
5. Also, one favor:
  Please delete the  Data which I posted:

Thank you
Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

Yes, okay this could be the issue with the Snapshots, they have not been consolidated....

and it's possible they still are consolidating...

what did you do, when it was at 99%

did you do anything?

you could have a hung VM, or Hung state ?

It is hung for the last 24 hours.
Did not do anything at 99 (except moved to another Host).  I guess I will wait for another day and see what happens. I did read your Snap Shot article "Be Patient".
Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

Something is very odd here, you would not have been able to move it to another host if a task was present!

can you check the disk properties, is it still on a snapshot ?
cgeorgeisaac

ASKER
Good question:

Originally the Disk was  Thin Provisioned
and now it is Thick Provision Eager Zeroed  - just do not know how it happened.
Your help has saved me hundreds of hours of internet surfing.

snapshot ?
cgeorgeisaac

ASKER
Yes could be.  Just do not know if it will automatically get fixed after few hours or it will remain stuck at 99%
Tried to power on now:    Message:   Another Task is already in progress.  An error was received from the host.
Will keep you posted.
Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

I need you to show me evidence, not guesswork...

screenshot of the disk properties within the VM, and then I can advise you...

Okay, another task in progress,,, is

1. Snapshot continues.
2. It's crashed and burned!

Please upload screenshot, and I also need a complete list of files in the folder. to check snapshot size...

free space on the LUN is what ?

Great advice. I will revert back after attempting to do as per your advice. Thanks again.

Meanwhile a quick question:

How come I do not see in the screenshot,  the  FLAT File  when the SnapShot is  created and running?
Also,  is the  -000001.vmdk the Delta File?
Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

-000001.vmdk the Delta File - yes that's the delta snapshot!

Because the screenshots were created by the storage API direct calls, by your backup application, they were not created manually by the GUI....

so, I can let you know how to proceed....(it's going to be a lot of hand holding..)
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

I have confirmed that  there is no backup.  Could you advise the next steps.
Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

We can try this a quick way....

Is it still stuck at 99%, or task in progress ?

before we do anything we need to clear this issue.
cgeorgeisaac

ASKER
Wow, I refreshed it and  now able to power on the machine.
Not too sure what may have happened. I guess all the SnapShot Files has been removed automatically.
However, could you advise what needed to be done if the issue had persisted?

Please check the virtual disks, if they are writing to a snapshot ?

snapshots needs to be dealt with?
cgeorgeisaac

ASKER
Positive. Only one .vmdk file all the  000001.xxx files (delta files) have disappeared. Thanks.
