Is it possible to mount a physical disk (/dev/mapper/ disk) on one of my Oracle VM server

I have a physical disk that I can see from multipath -ll  that shows up as such
# multipath -ll
3600c0ff00012f4878be35c5401000000 dm-115 HP,P2000G3 FC/iSCSI
size=410G features='1 queue_if_no_path' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=active
| `- 7:0:0:49  sdcs 70:0   active ready running
`-+- policy='round-robin 0' prio=10 status=enabled
  `- 10:0:0:49 sdcr 69:240 active ready running
That particular is visible in the OVMM Gui as a physical disk that I can present to one of my VMs but currently its not presented to any of them.
I have about 50 physical LUNs that my Oracle VM server can see.  I believe I can see all of them from a fdisk -l, but "dm-115" (which is from the multipath above) doesnt show up.
This disk has 3 usable partitions on it, plus a Swap.
I want to mount the 3rd partition temporarily on the OVM server itself and I receive
# mount /dev/mapper/3600c0ff00012f4878be35c5401000000p3 /mnt
mount: you must specify the filesystem type
If I present the disk to a VM and then try to mount the /dev/xvdx3 partition -it of course works.  (x3 - represents the 3rd partition on what ever letter position the disk shows up as)
Is this possible?

Its more of the correct syntax. Like I can not seem to figure out how to translate the /dev/mapper path above into what fdisk -l shows. Perhaps if I knew how fdisk and multipath can be cross referenced I could mount the partition.
I had already tried what you suggested. Here is the output if I present the disk to a VM and then mount the 3rd partition.
# fdisk -l

Now if I go to my vm.cfg file, I can see the disk that is presented.
My disk line contains
disk = [...'phy:/dev/mapper/3600c0ff00012f4878be35c5401000000,xvdh,w', ...]
Multipath shows that disk and says "dm-115" but that does not translate on fdisk

I have around 50 disks on this server, but the ones of the same size from fdisk -l from the server shows me many.

How to translate the /dev/mapper address into the correct fdisk, I think I can then mount it.
If I try the same command as before with the -t option it gives me this error.
# mount -t ext3 /dev/mapper/3600c0ff00012f48791975b5401000000p3 /mnt
mount: special device /dev/mapper/3600c0ff00012f48791975b5401000000p3 does not exist
I know I am close here, and feel it should be possible, I am just missing something.
Thanks for any help

  • What is the difference between Logical Disk and Physical Disk?

    Hi.
    When I do Performance Monitor, I got Logical Disk Avg. Disk sec/Write counter and  Physical Disk Avg. Disk sec/Write counter.
    But I can see the different Avg. value and Max. value. 
    Even if Logical and Physical Disk are one-to-one mapping.
    Why did i get the result?
    One the other hands, I got a same result that Logical Disk Avg. Disk sec/Read counter and  Physical Disk Avg. Disk sec/Read counter's Avg. value and Max. value.

    Physical Disk refers to an actual physical HDD (or array in a hardware RAID setup), whereas Logical Disk refers to a Volume that has been created on that disk.
    So if you have one disk with one volume created on it then the values are likely to be 1 to 1, but if you have multiple volumes on the disk, for instance a physical disk with C:\ and D:\ volumes running on it, then the logical disks relate to c:\ and d:\
    rather than the disk they're running on.
    See

  • Powershell- Associate Mount Point to Physical Disk

    I need to be able to associate mount points (Get-WmiObject -Class Win32_MountPoint) with the physical drive on which it resides.
    Scenario: I have physical disks (SAN LUNs) mounted as folders on an E: drive (also a SAN LUN) of a server.  I need to be able to, via a PowerShell script, associate the "folder" name to the physical disk (i.e., Harddisk4 or PhysicalDrive4).
    I can get Mount Point associated with the Volume, etc., but can't make the link to the physical disk.
    Any help is appreciated.

    Unfortunately there isn't an association class between mount points and physical disks like there is between logical and physical disks. I did a blog about finding partition alignment which required using Win32_LogicalDiskToPartition class. One of the comments
    suggested using Sysinternals diskext as workaround. See comments:

  • Upgraded to 10.4.9 on MBP 15", now, I can't mount external hard disk!

    Hi all,
    I have a LaCie 500GB drive that I've been using perfectly since I've gotten it, but alas, I upgraded to 10.4.9 and it no longer mounts either by it's USB interface or by its Firewire interface.
    My machine is a MBP 15" (2.16 GHz, 2 GB Ram), which works perfectly in all other respects and is now running 10.4.9.
    The symptoms are that when I plug it in, I usually get the message, "The disk you inserted was not readable by this computer" with the options "Initialize...", "Ignore", and "Eject". So far, I haven't pressed any buttons except Ignore or Eject. Sometimes, I do not get this message, but it still doesn't mount, it just silently does nothing.
    So, after pressing "Ignore", I've opened Disk Utility and had a look. The physical drive appears and there is one volume named "disk2s6" which for all purposes is probably my normal, logical volume (partition). However, last time it mounted on this machine, it was named "Archive". This logical volume is grey and will not mount no matter how many times I press the "Mount" button. It just does nothing.
    OK, so, while I'm in Disk Utility, I ran Verify Disk and, after the normal routine, it comes back with "No Repairs Necessary". I've also tried "Repair Disk" and this comes back "No repairs were necessary", again after the full, normal processing of the various things.
    I also performed a Fix Permissions on my startup-volume, but this didn't help either.
    Next test was to mount the disk on my MacMini (PPC) instead, also running 10.4.9. It mounts perfectly and it properly comes up with the name "Archive" as expected.
    I've then tried to mount other devices on my MBP including a USB memory key, and another external Firewire drive. These both mount perfectly on my MBP.
    While I was at this, I've also tried new USB and Firewire cables, this didn't affect my results in the least.
    I've finally verified that there is nothing in /Volumes out of the ordinary that might prevent it from mounting by doing a "sudo ls -la" whilst in /Volumes/. There's not a thing that would affect the mount-point.
    I then disabled my folder actions that I've been running on the directory /Volumes *I had an action used to backup my USB key). Unfortunately, I still have the same issue.
    Finally, I downloaded the Combo 10.4.9 installer, booted into Safe Mode (to trigger an automatic fsck), then rebooted and installed the 10.4.9 Combo installer, in case there was some weirdness in the Software Update upgrade to 10.4.9.
    What stone have I left unturned? Why won't this drive mount, but it works perfectly elsewhere? I want to get back to using Aperture on my MBP and my entire photo Library is on this disk (well, and backed up on another external drive, but it lives normally on my MBP).
    MBP 15" 2.16GHz + LaCie 500GB Ext Firewire drive Mac OS X (10.4)
      Mac OS X (10.4)  

    Here's some additional info...

  • Mounting an Apple disk image (Intel Mac) under other Unixes/Linux

    Hello,
    I have started my MacBook in HDD Mode and connected it via Firewire-Cable to my "Main-Server" (Slackware Linux 11.0).
    From there i created a "Disk-Image" from my MacBooks HDD using "dd"
    I can mount the disk image within OS X without any problems, but i can´t mount it on the Linuxbox.
    I have used this cmd under Linux : "mount -o loop -t hpfs image.dmg /mnt/tmp" But i am getting an error saying that it doesn´t seem to be a Apple File System Image.
    I have made sure that support for Apple FS is "compiled-in" in the Linux-Kernel. If i do a file image.dmg i get this:
    x86 boot sector; partition 1: ID=0xee, starthead 254, startsector 1, 117210232 sectors, extended partition table (last)\011
    Does anyone know how i can mount this image under Linux?
    Thanks,
    tyrtux.

    I can't offer any solution yet, but here's a bit of information that might prove useful in understanding the problem.
    "mount" on Linux mounts file systems, not disk images. A disk image is just that -- a bit-for-bit image of the sectors on what would be a physical disk. A file system is a portion of a disk structured in a specific way -- a section set aside for managing free space, a "root" directory, etc.
    A partition is a logical subdivision of a disk. Usually, each file system on a disk completely fills one partition; but partitions may overlap, and one partition may contain any number of file systems.
    A disk -- and therefore a disk image -- contains, within its first physical sector, a partition map. The map includes the start sector, size, and type of each partition. The type usually hints at what the file system -- if any -- of the associated partition is.
    When you connect a physical drive to a Linux system -- be it IDE, SCSI, USB, or CD-ROM -- Linux scans the partition table. You can then use mount to get access to individual file systems on the device. When you use "mount -o loop", you are asking mount to connect a loopback device to a file that represents not a disk -- but a file system. This is why your attempt is failing; the disk image doesn't look like a file system, it looks like a disk -- it has a partition table of its own.
    You might be able to map the file to a drive for VmWare, and access it from the virtual machine. Otherwise, I'd hunt around for software that deals with complete disk images, not just file systems.

  • How to use several physical disk ??

    Hi,
    I'll use BerkleyDB to store millions and millions of records.
    These records will need at least XXX Go on physical hard drive.
    Currently, 300 millions of records = 60 Go.
    But the number of records will grow exponentially
    Is it a way to use several physical disk to store BerkleyDB environement and associated DBs ?
    If is not possible, what is the best practice ?
    Using several environment on different disk ?
    Tks for your answers !!
    Regards

    Is it a way to use several physical disk to store BerkleyDB environement and associated DBs ?You can to spread a BDB deployment across multiple disks by using multiple environments in your application. Each environment would specify a distinct environment home. Preferably this would be configured to share a common cache, in order to have the most effective use of memory. See EnvironmentConfig.setSharedCache in JE 3.3
    Note that transactions are per-environment; you can't include operations from different environments in a single transaction.

  • Unreliable mounting of Firewire disks and Finder crashing

    On both my MacPro3,1 and MacBookPro5,1 running 10.6.2, mounting of Firewire disks is unreliable. Sometimes a partition being mounted does not show up in the Finder (but does appear as mounted to the df command). When that is the case, launching Disk Utility will cause the mounted partition to appear in the Finder. On mounting the disk, the system log always shows these entries:

    Hi Dr. T,
    > There is an OnDemand key in there which looks
    like it may be doing something useful.
       I'm afraid that I don't know anything about the contents of those files but yes, an OnDemand key sounds like it might do what you want. Although I'm still fuzzy on this point, I gather that what you want is for the device file to be created in /dev but for the volume to not be mounted. As long as the device file is created, you can use the path to the device file as an argument to the "mount" command to mount the drive at any time. I assume that one of "the relevant parameters" in the fstab is the path to the device file.
       I don't know how well I understand what goes on "under the hood" here because I don't do this a lot. I was of the impression that if you eject or detach a drive, the device file is deleted from the device tree. However, if you merely unmount the drive, the device file persists and you can easily mount the drive again.
       By the way, it is supposed to be possible to use fstab with only data that persists between boots. You can use drive UUIDs or labels to refer to partitions. You can use the df command to discover the appropriate device files at the moment and then "diskutil info <device>" to get the UUID.

  • Shareable Physical Disks - Missing files

    Fairly new to FiberChannel Disks here, but we bought the FiberChannel Disk Enclosure to support Oracle VM.
    So we have 2 OVM servers, that are connected to the FC Enclosure. We have created Volumes on the FC Enclosure and those show up as Physical Disks to Oracle VM servers. I then select those Physical Disks for each guest. All seems great.
    We only have one Physical Disk that is marked as shareable and is a part of 2 "guests". In one of the guests, the disk showed up, I created a partition (only 500G) and filesystem, and then mounted the partition. On the other guest, I did not need to create the partition or filesystem as fdisk alreadys showed it was created as expected. I was able to mount the partition on the other guest as well. All files and directory seemed to be visible and are accessible.
    I just created a new file on one of the guests, but the files does not show up on the other guest. If I switch guests and do the same, shows up on the one I created but not the other.
    If I umount and then re-mount the filesystem, the files show up. On my NFS mounts, I do not have to do this.
    My question is - is there something in my configuration that I have done wrong? Is there something I need to do to have files created on one show up on the other automatically.
    Thanks for all your help and advice.

Anything else would be way more complex to use. Alternatively, instead of using shared disks, use NFS or another network-based solution as you appear to have experience with this already.

  • Windows 8 and Possible Windows 7 64-bit Disk? laptop

    Well unfortunately i downloaded windows 8 and not knowing that i completely installed itself over my previous OS.(Win7 Home Premium) I lost the disk i got with my laptop so i cant re-install windows 7 and seeing how i thought it was unfair for me to spend another 100euro or so on it i was wondering if i could possibly get another windows 7 disk sent to me. I think it would be best if a staff member of hp itself would reply to my question. 
    Thanks
    This question was solved.

    Hi:
    No one working for HP will respond to your request on this forum in an official capacity.
    You can purchase a recovery disk for your PC's by reading the info at the link below.
    http://h10025.www1.hp.com/ewfrf/wc/document?docnam​e=c00810334&lc=en&dlc=en&cc=us&sw_lang=&product=40​...
    Alternatively, I have a solution that is better than nothing if you don't want to order recovery disks.
    Download the ISO file of the version of Windows 7 that is on the Microsoft COA sticker on the bottom of your PC. It must also be the version in the language that your PC original operating system came with.
    For example, if your sticker is windows 7 home premium and the language was Danish, select the 32 or 64 bit download of the windows 7 home premium - Danish file.
    Burn the file to a DVD using a program that can burn ISO files in order that you can boot from the DVD.
    Install Windows 7. Then use the 25 character product key on the microsoft COA sticker on the bottom of your PC to activate the installation.
    Then go the the HP support and driver page for your notebook and install any drivers you need.
    Link to the W7 downloads is below.

  • Physical disk for OS and read only filesystem after live migration

    I am running OVM 3.1.1 connected to an EMC storage array.  I have a situation where physical disks are being used for OS and binary filesystems (i.e. /u01, etc..) rather than virtual disks inside a repository.  When a VM is migrated from one host to another, I sometimes get a message stating the size of the disk changed and shortly afterwards the filesystem is changed to read only and I have to reboot to fix the problem.  Is this an unsupported configuration or do I have potential problems with my LUN mapping?  Has anyone seen this problem before?

  • Time Machine and mounted sparse bundle disk image - file by file backup?

    I think I had this system working in Leopard, but upon upgrade to Snow Leopard it seems to have broken. Does anyone have any idea how I can get Time Machine to back up the contents of a mounted sparse bundle disk image in real time - file by file within the disk image? For example, I have a 2GB sparse bundle disk image that i keep all of my bank statements/files/records in. It auto-mounts on boot and stays mounted. I use the disk image to keep it password-protected, so if I unmount it it is fairly safe. In Leopard, I would exclude the .sparseimage file from backup, but it would still backup the mounted image itself on a file-by-file basis, so I could enter Time Machine and explore the image folder by folder, file by file (say I deleted an old bank statement by mistake, I could go into time machine and recover as if it were a normal file/folder).
    In Snow Leopard, after a clean install, and creating a new sparse bundle disk image and excluding the .sparsebundle file, I can't seem to get this to work even though the image is mounted. Is there any way to trick Time Machine into backing up the mounted image as it would any other folder? I know I can back up the .sparsebundle file incrementally but in order to recover a lost document I'd have to remount the old bundle and that seems rather roundabout.
    Thanks,

    I think you're trying to bypass the finder to mount the disk. Try this (I'll bold the key steps):
    - *Turn off Time Machine* in the System Preferences.
    - Option A: If you directly use a hard disk (not wireless) that has the sparsebundle you want to open, *connect the disk* but don't double click on the sparsebundle.
    - Option B: If you are using wireless, this means use shift-command-k (or shift-apple-k), and if it says "Connect As..." in the upper right instead of disconnect, then use that button to *connect to that wireless drive*.
    - Confirm the sparsebundle shows in that folder before proceeding...
    - *Open Terminal* (Applications>Utilities>Terminal.app)
    - Type: *hdiutil attach -noverify* (<-- notice a *space " "* must be included after typing this here but *DON'T hit return* yet.)
    - *Drag the sparsebundle to the cursor in terminal*, and it should fill in something like /Volumes/HardDrive/COMPUTERNAME.sparsebundle for you. Now you can hit return, and the disk will mount.
    - After you are done browsing sparsebundle's mounted image, *eject the mounted disk* like you would any other disk (not the sparsebundle image itself, just the disk icon that appeared if you successfully mounted it).
    - Turn *Time Machine back on* in the System Preferences.
    Hope this helps.

    Is it possible to install Lion on the second hard disk on my Mini (2010) Snow Leopard Server, and switch between Lion and Snow Leopard? I like those voices Lion has in speech.

    When baltwosaid NO emphatically, that was described as CORRECT ANSWER. Ditto in the caeses of the radically different answers from  Camelotand Matt Clifton
    Could it be that CORRECT ANSWER needs better defining by Apple?
    That apart, yes, switching might involve rebooting. About the voices, well, I was the other day adding voice to a commentary in a video I was working on. There's only American English accent in SL — Lion I believe has British ones as well.
    Why not, I wondered, try to install Lion purely for academic interest, maybe with an SD card (Sandisk Ultra II, 16GB) as Tom Nelson says is possible at http://macs.about.com/od/macoperatingsystems/ss/Perform-A-Clean-Install-Of-Os-X- Lion-On-Your-Mac.htm
