Addition of physical disk to the server

Here's my situation, and I hope you can help. I am responsible for the upgrade of one of our PowerEdge R520 with a new hard drive. The server is a simple file server with 2 4 than to of disks in a raid 5 array. The raid controller that we have is a Perc H710. Seeing as how there are currently data client on the server, and it is used on weekly, duration of operation and keep intact/intact data is very important. The only way I see myself being able to integrate this new hard drive, if I create a virtual disk to OSMA. My problems is that there is currently not a virtual disk to re - set up is not an option. If I create a virtual disk, you see him causing problems with the current configuration of the raid? I'm almost certain, I'm just too react here because I never heard talk about software raid being able to re - initialize a raid configuration, while the OS is running. Needs to be done using the raid during the startup. Once the virtual disk is created, I should have no problem adding this extra hard drive. Should the virtual disk created before installing the new hard drive or is it really important? Any help will be greatly appreciated.

In addition, OSMA can see the disk that is not part of the picture and he said that loan, the rest are online. Currently, all I can do using OSMA is assign the drive as a hot spare. While it is useful, I need to be able to use the disk for storage. Once again, any help will be greatly appreciated.

Thank you.

You have several bays RAID configured on the same set of disks.  It is "cutting."  Online capacity expansion does NOT work on arrays into slices.  This is done more often to avoid the limitation 2 TB on boot floppies and/or compatible BIOS systems.

So, if you want to add disks to your existing RAID 5, you would have only two options: 1, 2 and 3, remove 1) VD expansion through to reconfigure, and then recreate your other VD again; or (2) backup data, wipe all the VD to create new VD (s), restore the data to larger VD.

In light of your installation, sounds like it will be easier for you to simply add the new drive as his own VD (1 disk RAID 0).

  • Problem with VMWare Workstation combo, .vhd virtual drives and physical disks in the sector of size 4K?

    All,

    I suspect something wrong with some of my virtual machines.  I have been using these virtual machines for a while, and I see some weird behaviour recently.

    I see a lot of corruption in the virtual hard disk (.vhd based).  CHKDSK automatically gets performed many large files such as Oracle datafiles get damaged etc...  It all seems quite random and inconsistent, but I am using .vhd virtual machines in VMWare Workstation for years without problem.  This problem is new, and hard drives are basically unstable.

    I * think * (and I'm totally off base) that is perhaps the issue with my new external hard drives.  These discs have a 4 KB sector size, without e512.  Thanks to this architecture of hard drive, don't mount not the tools of Microsoft or manupulate .vhd files on these disks.  The questions seem to go away if I switch to vmdk or switch to the physical hard disk size-one-sector 512kb.  Because errors are not compliant, that I don't really have a way to document/prove that is the case, but it seems to be.

    I use version 9.0.0 on Windows 7 Workstation, and the guest is Windows Server 2008R2.

    My question is:

    (1) what meaning?

    (2) how I prove/document, since it is a contradiction?

    (3) is this a known problem?

    (Btw, switching HDD's vmdk is not an option in our case due to an obscure legal agreement with Microsoft.  I have to distribute my VMs in vhd format, even if they are designed to run on VMWare...)

    -> Adam

    These discs have a 4 KB sector size, without e512.

    (I've highlighted "without e512" in "BOLD" to key in my answer to the host operating system.)

    -L'OS is Windows 7 Enterprise

    According to the political support for the 4 K sector hard drives in Windows, Windows 7 does not support the native 4 K (logical 4 k sector size) but it does not support Advanced Format or 512th (size of logical sector physical and 512 bytes of 4 K) and that is can be the question.

  • Widen the space of hard disk of the server host.

    Hello

    I'm looking for a good resource document that details how to increase the size of the disk hard comment server.

    I have a server windows server 2003 in a 50 gigs disc which is now full, a lot of space on the data store so I can increase the size of this drive.

    This is a quick and simple process, or is it going to take a long time to complete if someone can help me that would be great.

    Thank you

    Clint...

    Yes, you use 'Change settings' for the virtual machine and change the disc to the new desired size.  Make sure you have instant not on the virtual machine, and you can also do with the virtual machine.  Once the disc is resized in the virtual machine, and then the operating system supports the rest - exactly as you said.  The fact that the virtual machine never has to be turned off for this extension is the true beauty of the usage extpart.

    I warn you that it is always a good idea to have a backup of any system before making these types of changes.

  • Physical disk of the VM Win7 host access?

    Is it possible to access a physical host SATA disk in the virtual machine operating system?  I don't need to install Windows on the disk physical I only need OS in the virtual machine to see the physical drive directly. The host is Win7 x 64 guest is Win7 x 86.  I saw some documents on this site, but it seems to be contradictory.   I noticed there is an option to add a physical disk, but I never got to actually do something.  So I was wondering if anyone here knows how to run?

    Putting aside the question this thread mentions new possible for rawdisk workaround access under Windows 7 if your talking about access to OS system disk the host as a raw simultaneously from the VM disk, even if it were possible, corrupt you the file system, as a BONE can directly control the physical hard drive at a time.  It must therefore be a second physical disk that was not the system drive, where the virtual machine may take control of the host.

    Hello. I use 3 Player VM and Guest OS Windows Server 2003. The host OS is Windows 7. I need to increase the size of the VM disk, so who can install several systems in the guest OS. If something bad happens during the expansion of the size of the virtual disk, the guest operating system and its Applications will not work. Thus, before expanding the size of the virtual disk, I need to back up the virtual machine hard disk external.

    I have check the disk hard host operating system Windows 7, the path is C:\VirtualMachine\WindowsServer2003\... When I get to the top of the virtual machine on the external hard drive, simply select the 'VirtualMachine' folder and save automatically. I have 3 questions as follows:

    First of all, if something bad happens during the expansion of the size of the virtual disk, the guest operating system and its Applications do not work. Can I just delete the folder 'VirtualMachine' in the host operating system?

    Secondly, the problem of the first question does not affect files in the physical hard disk to host operating system?

    Third, if something wrong happens during expand the size of the virtual disk of OS guest, I simply delete the folder 'VirtualMachine' in the host operating system and load the original 'VirtualMachine' from the external hard drive in the host operating system. Works correctly as long as one is the Virtual Machine before Stude the virtual disk size?

  • Comparing the use of the data store for the use of the disk on the server virtual computer: Match is not

    I'm a bit confused and could use clarification of a person.

    I'm looking to a virtual machine through the vSphere Client and it has an alert telling me that my free space data store is low. 17.55 free GB of 134,75 GB total capacity. I'm running ESX 4.0 for the host and my VM running Server 2008.

    I'm confused because when I connect to the virtual computer and check the use of disk in my computer, it does not reflect what vSphere tells me. This particlular VM is little used and the use of the disk under windows is very very low. About 20 GB.

    Can someone tell me why these numbers are not matching? I have other virtual machines that are in the same situation.

    Thank you

    Blake

    I think that you may be mixing two things up, the vSphere client will only warn about the data store, the VMFS volume, you have created and presented to ESX. You then create a VMDK file for your Virtual Machine to use. If you assign more than 80% of your data store to a VMDK or several VMDK then the customer will report a warning on its use. WARNING 80% 90% critical even if inside each VMDK file you may be using only a couple of GB.

    If you give a little more detail on the virtual machine and the data store, we should be able to get out.

    Hope this helps,

  • Hard to reformat the disks on the Server Blade

    We just installed a blade with 4 servers M620 m1000E chassis.  I'm looking at a variety of new Virtualization options.  One product claims a previous installation has failed and the obvious solution is to format the drive (mirrored 136 15K SAS) and reinstall.  The problem is, I have not met this before, and I am really uncertain how can I achieve this.  The installer doesn't have an option to reformat before you install it.

    If anyone has a suggestion, or can point me in a direction I would be very happy.

    Darwin

    56Nine,

    What you would do is access to the controller on the M620 via the Control Panel, and then select device settings, then the Raid Controller in question. From there select Virtual Disk Mgmt and virtual disk operations. You will see the choice between fast, slow to boot initialization and check the consistency. Select the fast initialization and start again. Now a reminder, this will delete all data on the disks, so if these data are necessary Please save the first.

    Let me know how it goes.

  • Remote desktop / mapping of disks on the server 2.0 vmware instance

    Hi all

    First post so go easy on me!

    I have vmware server 2 is installed on a computer laptop windows 7. I have a windows server image 2003 running on it.

    When I'm on my home network, my laptop has an address IP (DHCP) and my OS VM also (also DHCP).

    I can map a network drive and connecting via remote desktop.

    If I'm not on a network, I can't do these things, my computer laptop operating system (windows 7) can not see my guest OS (windows server 2003). Is it because they have the 169.meta XXX address?

    I have to hard-code the IP?

    The idea is to be able to take your laptop anywhere, so not always connected to a DHCP server.

    Thank you

    Shaun

    That's how add a second NETWORK card, but it must be or NAT, not bridged, host-only so that the host always being able to connect to the client when you have no available bridged network. You will get the 169 address with full because your DHCP server is not reachable. Do an ipconfig/all on the host to see what subnet the adapter vmnet1 is about who is the subnet on which the guest will be too, since one of VMware DHCP server IP address.

  • 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...

  • Connect physical hard disks to the virtual machine (and leave the data intact)

    Hello

    I'm looking to virtualize a SOHO headless server, that I use mainly for secure file storage.

    Currently, the system runs Linux installed on a small disc and has two drives 1.5 TB, used exclusively for data, in a cluster of ZFS mirroring. (I use the ZFS-fuse Linux-based application).

    I want virtualization for two reasons. One is to make administration easier and safer - avoid having to connect a keyboard and the physical monitor to the box from time to time. The other is that the machine is a bit more powerful to handle the load, and I'm hoping to make it work on other, more challenging tasks.

    Now, there is a catch. These discs are as highly important. I mean the data on them. What I need is to convert the current Linux system to a virtual machine, or re - install Linux on a virtual machine (don't like that), then connect the physical disks to the virtual machine as if they were actually connected.

    I certainly don't want to vmware touches those disks somehow.

    I've read the documentation, but I'm a noob when it comes to server virtualization and system engineering and don't quite understand if this is possible or not. These discs are not a SAN, they are physically connected to the server, I want to install vSphere on. (Of course, I'll log out when I run the setup of vSphere. But I need plug them again later, and they need to be sure that vmware will leave them alone and pass them to the virtual machine transparent.)

    Sigmoid wrote:

    Oh yes, the cluster mirrored ZFS. It is essentially a software RAID type thingie.

    http://en.Wikipedia.org/wiki/ZFS

    A material, or the point of view of virtualization, it appears two hard drives with a single huge partition on each that is not transparent to anyone, except the implementation of ZFS.

    OK, means that you can break the RAID, connect the drives to different host and configure RAID once again, right?

    Let's do it this way

    1. We will need a disc player more for VM, cause on flash, we install ESXi
    2. I will share ZFS :-), all you need to do with that before you install ESXi
    3. make the BACKUP!
    4. Disconnect the data host drives
    5. install ESXi 4.1 U1 free version on flash
    6. Download the site VMware vSphere client
    7. Connect the VM disk to ESXi
    8. customer help create the virtual machine and install the OS on it
    9. stop the virtual machine and esxi
    10. connect DATA drives to the ESXi host
    11. begin to ESXi
    12. See how to add RDM on youtube, after client use, change first hardware VM--> add a new hard disk--> choose Raw Device Mapping--> (physical or virtual) mode--> store it with folder VM - FACT

    I installed 3 of the disks individually rotating as a single HARD drive with similar results.
