Physical disks in taking snapshots

I looked at some posts earlier, but I didn't understand about how to take a snapshot of a virtual machine that includes a physical disk.  In my case, the physical disk is a dd image file mounted, well I'm not sure it's important.  I see that I have no option to create a snapshot in the snapshot GUI Manager.  So, I tried vmrun, which seemed to work.  I noted, however, that vmrun created about 40 snapshot files, named in a convention of VMname-000001 - s001.vmdk, VMname-000001 - s002.vmdk, etc.  They each about 320 KB.  I created the capture instant vmrun when the virtual machine has been turned off.  I use 7.0.1 on a host of Win 7 64 and my guest is Win 7 64.  Thank you.

Hi Jimmy

as far as I know you always get snapshots in 2 GB slices when you work with physical disks.

Also 2 gb slices if you create snapshots with snapshotmanager.

I just did a test using two ways, and both times the VMDK was the same - 2 GB slices.

If you really really you can manually create the monolithic snapshots of rawdisks - like that

# Disk DescriptorFile
version=1
encoding="windows-1252"
CID=75ffb14c
parentCID=495c0932
isNativeSnapshot="no"
createType="monolithicSparse"
parentFileNameHint="rawdisk.vmdk"
# Extent description
RW 976773168 SPARSE "rawdisk-000001.vmdk"

# The Disk Data Base
#DDB

ddb.toolsVersion = "0"

attached to this parent

# Disk DescriptorFile
version=1
encoding="windows-1252"
CID=495c0932
parentCID=ffffffff
createType="fullDevice"

# Extent description
RW 976773168 FLAT "\\.\PhysicalDrive1" 0

# The Disk Data Base
#DDB

ddb.virtualHWVersion = "7"
ddb.uuid = "60 00 C2 9e 98 f0 c1 24-49 4a 2a d1 a9 b4 74 78"
ddb.geometry.cylinders = "16383"
ddb.geometry.heads = "16"
ddb.geometry.sectors = "63"
ddb.geometry.biosCylinders = "1024"
ddb.geometry.biosHeads = "240"
ddb.geometry.biosSectors = "63"
ddb.adapterType = "ide"

I just found out how to do it-hardcore - very experimental stuff

-You have a strange disk geometry

DDB. Geometry.Cylinders = "9767850".

DDB. Geometry.Heads = "32".

DDB. Geometry.sectors = '2 '.

ddb.geometry.biosCylinders = "9767850".

ddb.geometry.biosHeads = "32".

ddb.geometry.biosSectors = '2 '.

I've never seen such values before... If the drive behaves strange I would rewrite her to normal values

  • 6 - physical disk space - where she went from ESXi

    I use products VMWare 10 years and more, most of this being VMWare Workstation.  On my laptop (500G HD), I currently have about a dozen virtual machines of the 2012 to Windows XP for testing server.  I also have dozens of snapshots.  If I look at my physical disk used space, the foregoing takes 330G of space.

    I decided to buy a dedicated device and create an ESXi environment that more closely reproduce my customer environments.  I have a HD 500G with 16G memory on an i7 platform.  I downloaded the iso of ESXi, created a bootable USB key and installed.  Connected with vSpere Client and started installing VMWare customers.  After my 6th VMWare guest, I had 65G of free space left.  I installed the following

    4 Server HD 2012-60G each

    1 Windows 8-40G

    1 Windwos 7 = - 40G

    Even if all the virtual HD prealloue were (I don't believe that they are), the foregoing would be only = 320 G.

    If I look at vSpere, it says that I have a capacity of 458G with only 65G left.

    Thus, the question, it seems that its allocation of space for HD and with fees generals, I can see where the above figures comes, but is one of the benefits of virtualization to share the resources.  It is a framework in ESXi that does NOT allocate all the space when you create a virtual guest.

    When you work with work stations, it will create the files on disc as a provisioning. The default value in vSphere is to create disk thick available zero lazy. It will allocate all the space of the disk if you don't have a disk VAAI system api. When you create environments on your computer and ESXi is installed make sure you thin when, available when setting up servers or it will fill up fast.

    You will be able to choose the layout thin when you select the size of the disk when you create virtual machines in ESXi. There are 3 options thick available zero lazy, thick available zero willing and thin provision.

  • VMware Vista support physical disk device does not not for some VM.

    I handle Win2k8 64 bit vm on esx5.5 Update 2 which are evidence of "Disk of Vista VMware help" have the error "this device is not present, is not working properly or is not all its drivers installed." (Code 24) ». Versions of VMware Tools vary, either 9.4.0 9.4.5 build-1585188, build-1598834 or 9.4.10 build-2068191.

    Google missed most of the time. I can't find any information on what concrete this virtual device is or what it does in particular, except that it may be involved in the creation of snapshots suspended.

    In addition, the device seems to be attached to the vmrawdsk service, which does not exist on the server. These virtual machines were not P2V, they have been created since iso win.

    One guess what it is and how I might be able to fix it?

    I got it on a working server my copy on the file vmrawdsk.sys missing a server well-known, uninstall VMware Tools, restart, reinstall it and restart again. Then the VMware Vista support physical disk device / service vmrawdisk are working normally.

  • VDR 2.0.1 / dev/sdb /-physical disk not rise, destinations

    Hi all

    I have a problem with my VDR 2.0.1 last backup has been the failure due to power and after that problems on VDR destinations where I had destination normally one network, stay another one, physical disk no rise/dev/sdb /. I can not remove from vClient cause it says "destination is in use", but there is not any visible running task. This physical disk is exactly the same size as one of my VM who began with backup when possible failure has occurred. Also, under the VDR icon in vClient I see the same VM hard file.

    That's happened? How can I mage it?

    Concerning

    Kris

    Remove the disc from VDR-VM-mixer under 'Edit Settings' with Remove.

    That make a snapshot of the virtual machine affected and after that delete all the snapshots of this virtual machine.

    Normally this will solve these problems, if VDR was interrupted during backups.

  • Reference Dell MD3000i and degraded physical disk channel

    In this case recovery guru say "you must contact your technical support representative to correct this defect. Do NOT try to fix this problem yourself. So, how we can receive technical support recommendations and try to repair this failure?

    If you need more details, we can put any storage array profile output.

    Hello UtkinE,

    Yes, you will need to stop all iSCSI traffic so that you can update the NVSRAM.  With the timeout error you get all came from controller 1 & he had only discs 1 & 5.  The current version of NVSRAM you version 4 and the last one which is for the MD3000i is version 13.  With who have older firmware it was improvements to correct your problem in the latest versions of firmware.  I also had one of our analysts will confirm as well just to make sure that it is the best fix for your problem.

    Please let us know if you have any other questions.

  • Degraded physical disk channel MD3000i

    I get this error on my MD3000i we have a connected to the MD1000. All discs show optimal, but disk channel 1 shows optimal disk channel 2 shows degraded.

    Here a technician Dell here I can send zip support for?

    Hello grendels_Arm,

    What I would do, is to clear the statistics of physical disk channel. Here are the commands that must be run:

    SMcli n Pei password - c "clear stats allPhysicalDiskChannels;

    SMcli n Pei password - c "set physicalDiskChannel State [0] = optimal;

    SMcli n Pei password - c "set the status of physicalDiskChannel [1] = optimal;

    If you still get the error after erasing all channel statistics, then we need to look a your MD3000i support beam to see what the cause of the error still occur.

    Please let us know if you have any other questions.

  • MD3000i individual physical disk - gradient path

    Recently, we have replaced a failing in our MD3000i HARD drive. After letting it rebuild, all the disks are again in an optimal state. But the recovery guru still gives this error:

    Individual physical disk - gradient path
    Gradient of physical disk paths:
    Channel: 0
    Physical disks: (unknown)

    Can I support safely on "Check again", or what would be the procedure I should follow to get rid of this error?

    Hello Diss,

    Since you say that when you look in MDSM all readers are also optimal then you should be able to do a recheck out the recovery guru & have it checked to confirm that all the drives are online & optimal.  If after you run the recheck if the cottage no matter what drive as still having problems, then what I would do is to recheck MDSM & confirm that the drive displayed as failed.  The error normally clears once a car has been replaced but in some cases I see need to run check again to clear the error recovery guru.

    Please let us know if you have any other questions.

  • AGAIN starts after only one physical disk has several partitions makes no sense to the production oracle database?

    Dear Experts,

    Don't + REDO1 diskgroup have only one physical disk has several partitions makes no sense to the production oracle database?

    For example

    • + Diskgroup Redo1 have 2 50 GB disks (fact these 2 discs are the same physical disk partitions OR these should be separate disk as recommended approach)?

    Hello

    Partitioning your disks for ASM configuration as 'A' might make sense. If you lose one disk, you have the discs to another.

    'B' totally make sense if you have lost the disc that you have lost all group ASM and you need to change this with something like 'C '.

    But obviously you need redundancy ASM configured appropriately.

    Kind regards

  • T310 degraded virtual disk, all physical disks 'online '.

    It is a PowerEdge T310 server. Physical disk 0:0:3 showed physical way errors in the past, but after reinstalling the drive, everything was going well for a while. Now Dell OM reports that the virtual disk is degraded, but all four disks are online reports and have this green check mark by them.

    Nothing shows expected failure and I don't see any disk medium error, the firmware is up to date - is their something I don't see as to why my virtual drive would fail? I think there is always a problem with PD 0:0:3 even though she does not appear in the newspapers. Any input would be greatly appreciated. Thank you.

    PowerEdge T310, degraded virtual disk as of 04 21, 2015:

    All the physical disks on the other hand are very well reports:

    Errors of the past and present newspapers:

  • Fusion Pro 8 still requires the administrator password to log raw physical disks at startup

    I'm 10.11.3 El Capitan server running in an instance of VM Fusion 8 running on a 10.11.3 host El Capitan.

    For performance reasons, I connect Raw / partitions of physical disk using the links generated with the vmware-rawdiskCreator command line tool and added to the .vmx file.

    My question is, since it is a server, I want it to load VMWare Fusion and start the virtual machine automatically at startup, but each time the virtual machine is started, a message appears stating "VMware Fusion requires administrator privileges to access Boot Camp disks.  Type your password for this purpose".

    Some research that it used to be far to say merge to "never ask" passwords, but this feature doesn't seem to be an option of Fusion Pro 8.

    Is there a work around to bypass the manual password entry requirement?

    OK, I found an answer to my own question...

    Although it doesn't seem to be an option to disable the prompt of the graphical interface of Fusion Pro 8, there IS one on the command line.

    First, find the UID of the user account that you launch VMware Fusion with the help of.

    ID

    (Often this will be 501 as the UID of the first user created on any mac).

    Then run...

    The official version said that WS allows only virtual up to 8 TB of disk.

    According to my own tests, it only limits the size of the VMDK for 'New - VM' Assistant.
    Once you have a greater vmdk - just tried a vmdk 10TB - WS won't complain about the size.
    I don't expect that WS will prevent the physical disks to use inside a virtual machine that is already configured.
    So in your case I think you started WS with a normal user account.
    Try to start as administrator WS - maybe even using the administrator account.
    I think that then it will work.
    Unfortunately, the error messages produced by vmware.exe are not really accurate-, so there is no way to know if you really have a bad super block.
    To test if this is really the problem and not just an error message - poor try to mount the drive directly.
    Please post the vmdk - want to know if there is something unusual about 5.5 TB in the disk.
