• How to-disk snapshot RDM in physical mode and RDM issues.

  Hi all

  I want to upgrade a few VMS version 4 to 7 production equipment, so I can save them using vDR.

  One recommendation is to take snapshots of the necessary virtual machines before the hardware upgrade, I'm unable to do so because of the disc RDM in physical mode.

  I'm looking for the answers to the following questions:

  -How do we or can we change disc RDM in physical to virtual (all risks, process involved, etc...)?

  -How a US dismantle and mount RDM disk without losing any data?

  -Can we dismantle and mount RDM disk to a different virtual computer?

  -We convert RDM to a normal virtual disk on vmfs data storage?

  Enjoy your time reading/response.

  Hi dia,.

  Please find the answers online.

  -How do we or can we change disc RDM in physical to virtual (all risks, process involved, etc...)?

  Remove the drive from RDM virtual machine and add the ROW again using virtual mode.

  (Do not select the option Remove evil in the virtual machine and delete the files from disk)

  -How a US dismantle and mount RDM disk without losing any data?

  Same as above. (if I understand your question)

  -Can we dismantle and mount RDM disk to a different virtual computer?

  Remove from VM-1 and add the VM-2 by using the VM settings.

  -We convert RDM to a normal virtual disk on vmfs data storage?

  Yes, we convert RDM on the virtual disk using the Migration (SVMotion). To do this the virtual machine must be powered off the coast of the State.

  Let me know what answers your questions.

• VMotion VMs Wit RDM

  People,

  Can you vmotion a VM with RDM LUN inside from one node to another in a cluster on the fly?

  Also, I would like to know if I put the ESXi in maintenance mode, all virtual machines including those with RDM connected gets vmotioned to other nodes in the cluster automatically

  Rahul-

  Hi Rahul

  It is stated in the Documentation that you can use with VM with RDM vSphere vMotion.

  Documentation Center of vSphere 5.5 - on Raw Device Mapping

  With RDM, you can:

  - Use vMotion to migrate virtual machines using raw LUNS.

  
  

  If you use vMotion to migrate the virtual machines with RDM, be sure to maintain Consistent ID LUN for RDM on all participating ESXi hosts.

  Considerations of RDM & limits are listed here: Library of vSphere 5.5-RDM considerations and Limitations

• An error occurred in consolidating the discs: msg.snapshot.error - DUPLICATEDISK.

  Try to remove some snapshot using vSphere, it fails.

  Tried to turn off the virtual machine. Create a new one and then consolidate but it fails.

  «An error occurred by consolidating the discs: msg.snapshot.error - DUPLICATEDISK.»

  Any ideas?

  Do not know what is happening, I understand that the snapshots are in a bad state for a reason I don't understand, however, I just want to remove all the.

  Ultimately that I restored a backup that comes with Veeam this backup did not have snapshots but was the most recent copy.

  Restore the virtual machine, and there is no instant, there was no need to consolidate.

  Some people said that to fix the error, you must fix the instantaneous chain. Which is probably a particularly risky and complex process with multiple nested snapshots. I have this mark as resolved, but if someone wants to contribute on how to fix this problem manually, or simply to force a fresh copy and to ignore snapshots please post and share.

  Thank you

• Removal of VM snapshots will help to reclaim storage

  We found about 8.1 TB of data store space used by the VM snapshots that we asked teams to go and remove as many of them created long back.

  This will help me to regain the 8.1 TB of storage or only some GBs

  mubaraksardar,

  If you remove these snapshots of that space will be available on the data stores again. I hope that you have a version of ESX which is most recent few years that the remove snapshot feature has changed over the years.

• Recommended method to remove a snapshot of the VM?

  Recently, I tried to remove a snapshot of a virtual computer Manager of VM snapshots.  The virtual machine was 80GB in size with an existing snapshot of 50 GB, I gracefully shutdown the OS/VM before you remove the snapshot.  Once I started the withdrawal, all was well until we arrived at 95% (the number 95/99% we all know).  After some research, I decided to cancel the process and restart management via the host services.  This solves the problem and the snapshot appeared to remove.

  A few days later, I was working on another task and ended up experience of the 'an internal error has occurred... ". "Details: object reference not set.... error, this has taken a while to correct but has finally been resolved.  It showed me I thought the snapshot previously removed, not actually are deleted;  I have now lost confidence in the VMware Snapshot Manager!

  As I have to go through the process of elimination of many VM snapshots, in the coming weeks.

  I want to avoid having to experience this kind of problem again, I want to make sure that the snapshot of the virtual machine is deleted and as fast as possible.

  Is there a better way to go through the snapshot deletion process?  Perhaps via the CLI or a tool/utility VMware or third?

  Is there a "verification process" that can be taken to ensure that the snapshot has been actually deleted?  It seems that I can't trust GUI/vSphere Client when it comes to check the instant withdrawal.

  Look at the Snapshot Manager is a reliable reference point in environments with fast, healthy and instant storage infrastructure that does not grow very large (50 GB is very large).

  As a.p., VMware snapshot handling is super reliable, so don't panic when the Snapshot Manager does not display what you expect.  ESXi is very strong in keeping your data via instant recovery logs.

  To answer your questions:

  "Is there a preferred way to go through the snapshot deletion process?  Perhaps via the CLI or a tool/utility VMware or third? »

  -The first step is to prevent snapshots more and more very large sizes and keep sufficient free space on your data for overhead warehouse operational.  Insofar as the preferred method, continue to use Snapshot Manager.  If you think that the virtual machine still works from a snapshot, you can see these files in the data store Navigator.  In the past, we had to use the CLI of ESXi to merge and clean up the trees in the snapshot safely.  VMware has introduced a version of this method in 5.x GUI.  It is called "Consolidation".  See this excellent KB article:

  VMware KB: Consolidation of snapshots in vSphere 5.x

  "Is there a"verification process "that can be taken to ensure that the snapshot has been actually deleted?  It seems that I can't trust GUI/vSphere Client when it comes to check the instant withdrawal. "

  Manager of snapshots and the field "A need for Consolidation" are your first indication.  Understand the snapshot files stored with the virtual machine will give you a greater level of comfort with the internal components.  I recommend this article:

• using snapshot script

  Most the script below for list of snapshots is spent for me (I made a few small changes) and it works fine except that it does not list the creator of the snapshot, but rather as the creator of the last snapshot even if there is not, instant vDP, for example.  In my opinion, it's how the Get-VIEvents is called instead to get the instant creator of the command get-snapshot.

  Is anyone able to point me in the right direction, or use another method to find the instant creator?

  Thank you.

• Alert shadow in vSphere PowerCLI script

  Hi all

  I have been using the script from this site with great success.

  http://vnucleus.com/2011/07/PowerCLI-script-to-alert-on-snapshots-in-vSphere/

  What I'm trying to understand it how to change the script, then he will send a report, even if there are no snapshots on virtual machines?

  Can you get it someone please let me know what I should do?

  Thank you

• On the deletion of the snapshot

  Hello

  I have a guest host ESXi 4.1 with a BONE (Cesto). The total space of the VMFS(data store) score is 550 GB. Out of 550 only 25 GB is now available. There are 4 snapshot of this OS (the last is 250 and the first 45 GB) Guest. I want to remove the snapshot 1.

  1. which is the best way to remove this snapshot?

  2. If I want to delete the snapshot using vSphere Client, what are the effects of negetive.

  The client is a server hosting with 200 clients, so I can't bare the downtime. Please give me a better way to do it. If possible, please provide the links to complete these steps.

  Thanks in advance.

  Basically, I agree with continuum and cloning would be the safest way to do this clean up. However if I understand the situation, you should be able to delete the snapshots with the virtual machine without interruption of service. What I realized, this is:

  • you run ESXi 4.1
  • data store size Go 550, 25 GB free
  • all snapshots appear in the Snapshot Manager
  • the virtual machine is the only VM on this data store
  • VM has a thick drive put in service (adding the size of the files, this should be the case)

  can you confirm this?

  In this case, you can remove the first snapshot (the one closest to the basic disk) without needing additional disk space, with the exception of the changes that go to the most recent snapshot. With 25 GB of free disk space, that should be ok! After the first snapshot was merged on the basic disk, you should have 80 additional GB of free disk space (according to timestamps, 000002.vmdk snapshot file is the oldest snapshot, the file names are not necessarily in ascending order), in which case you can now decide to continue to clean up snapshots by one or by using 'Delete All' to get rid of all snapshots.

• Creates a snapshot manually, now they continue to fill storage; suspension of error

  A few days ago I created manually a snapshot in vSphere 5.1 on my Exchange Server.  Soon after, my virtual shutdown due to lack of storage space.  I deleted the VMDK with 0001, 0002, etc. and because of the problems (of course).  So, I restored a snapshot of my SAN on the volume level and was able to consolidate snapshots and free up enough space to start the virtual machine.  Everything worked well for a few days, when I suddenly started getting this error again and stops the virtual machine.  In the last days this snapshot is repeatedly be recreated in some way, even if I don't have anything on demand (I can not even find WHERE them planning this!) and it takes my whole Exchange server down.  I begin to receive an error indicating that VMware may not be suspended, and then shortly after that the virtual machine stops again due to lack of space.  I already gave him more space to my SAN, but it continues to happen.

  Whenever I am able to simply consolidate snapshots with VMware, but it fell three times in the last twenty four hours.  How to stop these shots?  Help!

  If you don't create snapshots yourself that they are either created by a tool for automatic backup (misconduct) or Autoprotect.
  AutoProtect is rarely used on ESXi as well as your backup tools?

• snapshots are not 'live' using powercli

  Do not know what is happening, or maybe I'm just something missing. We wrote a few scripts to take snapshots and return machines on our esxi server. The scripts use the PowerCLI. Scenario: set up a group of virtual machines with a particular State (e.g. connected applications that are running, etc.) and take the shot. I want to be able to return to that State. It works fine when I take a snapshot using VSphere client GUI... take a snapshot, back to him, the machine has returned to is running and in the correct state.

  Problem is the use of the script of PowerCLI - snapshots say they are taken, but when I return to the rupture, the machine is broken and needs to be restarted.

  What Miss me?

  Thank you!

  You use the '-memory: $true' option?

• Snapshot TIME?

  Are there features of snapshot for vApps in vCloud Director?  What happens if I wanted to test something with a group of virtual machines or a single VM in a vApp, go back, and I had no access to the vSphere Client?  Is there a similar functionality as that of snapshots in vSphere?

  Unfortunately not. I hope that it will be available in a future release. The only option and it's not great, I can think of is to make a hot clone via the use of the API. There is a guide to the conduct of this orchestrator which should point you in the right direction but this isn't really a snapshot than a backup http://www.vcoteam.info/learn-vco/vcloud-director-vapp-hot-clone.html.

• problem with deleting snapshot

  Hi all

  I had a preview of the virtual machine on a server esxi 4.1, build 320137

  When I later (1 day) removed the snapshot (action to "remove all" in the snapshots in vSphere client Manager), I got an error saying:

  Delete all snapshots

  < myvmname >

  Cannot access the file

  < not specified

  file name > because it is

  locked

  root

  At this point is no longer the snapshot, according to the vSphere client as well as the command line:

  / vmfs/volumes/4cb6cf27-7 d 884680-68bf-00221965eca8 # vim - cmd vmsvc/snapshot.get 176
  Download Snapshot:

  (176 is the vmid of my machine)

  but in fact, the snapshot is always present, with delta 3 (one for each disc) of about 1 GB (it's a busy machine, with 1 disk 16 GB o.s.

  and 2 200 GB, nearly full drives)

  the question is: what can I do to merge the delta vmdk into their respective discs?

  Or what I can do to create 3 new discs containing all the data, for example using vmkfstools

  (then I'll replace it with these new old records in the vm configuration)

  Operations can also be done in turning off the State without any problem (night...)

  Thanks in advance,

  Andrea

  printing to see it regularly here :-)

  First, take a look at the contents of the virtual machine or watch the vmx to check file that VMDK is being used.

  one you have you need to consolidate the VMDK for this virtual machine must be downwards as in the contrary case, it locks files.

  and then you start vmkfstools-i/vmfs/volumes/datastorename/vmname/vmdk-from-vmx-file new.vmdk

  You will need to run it for all discs, you have on this virtual machine.

  This will consolidate the VMDK, but this alters the 'old'. You must then modify the virtual machine settings and remove the old drives and add custom discs using the new vmdk, you created.

  Once the virtual machine is running, you can clean the old files...

  Good luck

• How to set the number of unit and its maximum value in RDMS

  Hello

  I am trying to add RDM vsphere sdk using the code to return the controller below key and the unitNumber:

  length +1 ;

  if (retVal [1] == 7)

  retVal [1] = retVal [1] + 1;

  return retVal;

  }

  }

  return null;

  can someone tell me please:

  1 how to get units available, for example for example: 0-15

  2. how to get/set the limit (15)

  3. how to do ROW when the unitNumber reached 15

  4. how to ROW with the next value as SCSI1:0, after reached SCSI0:15

  Hello

  have you tried manually in your environment in order to add the new controller scsi as "scsi controller 1" for VM? First, try manually, then make sure that the scsi controller option is allow to add a scsi controller more for VM.

  And in your code

  scsiCtrl.setBusNumber (0); I think that the scsi controller 0 is already set. This is so it will be like this scsiCtrl.setBusNumber (1);

  scsiCtrl.setControllerKey (1000); This line will not come because after you add the scsi controller, it will generate key controller. It is not depends on user option

  Apart from that, I think that some description and label is not necessary.

  Thank you
