Remove the OS disk

Dear all,

We plan to do these operations. Currently, we have two groups of disks for FRA:

-FRA - two members FRAVOL1 and FRAVOl2 drives

-FRA1 - drives a FRAVOL3 Member

Disk groups "FRA" is a former flash recovery area volume which is corrupt - clerical errors. We have created the second disk group to move the flash recovery area to it. Now we want to remove the FRAVOL1 and the FRAVOL2 system (FRA disk group is dismantled and removed), but we have some doubts about this operation. The FRAVOL1 is the disk/dev/sdb, FRAVOL2 is the disk/dev/sdc and FRAVOL3 is the disk/dev/sdd. One wonders what will happen if we remove/dev/sdb and/dev/sdc (Oracle Enterprise Linux) OS disks? / Dev/SDS rest as/dev/SDS and more importantly if the DSO will always see this drive as a drive of ASM members and we will be able to start the database.

Thanks for any help.

Best regards

It seems that you have defined the ASM starts as EXTERNAL redundancy.

To eliminate the disks, you must properly DROP DISKGROUP start.  Make sure that the DiskGroup is longer in use!  Check that you have correctly reset db_recovery_file_dest

As or if/dev/SDS home/dev/sdd, Linux can relabel discs to reboot.  That's why asmlib is used to label privately within the DSO OR udev rules are used (my guess is that you need to update your udev rules, if you delete/dev/sdb and/dev/sdc)

  • How do I change or remove the password disk HARD on my Tecra A9

    Hi all

    I looked for where I could, but didn't find any indication at all, so I'm asking here.

    I have a Tecra A9 in need of resettlement, what I like to do for me.
    I have a very good password on the HARD disk which I do not wish to give. So I want to change it or remove it completely.

    Please someone, how do I do? In the BIOS, I don't see that it has been defined, but all what I try, I can not change or get rid of it.

    Maybe I should add that since the original installation of the PC it was years ago and I don't remember not the 'Administrator' password.

  • Removed the HARD disk with MBR/BCD who installed Vista x 64 Business on the new HARD drive

    I have vista x 64 business installed on a HARD drive, but it was (and still is) installed on an older HDD aswell and the smallest, the result being that when I removed the old hard drive to put in another computer, I was unable to boot the copy of vista on the new HARD disk as the MBR or the BCD bit that allows me to choose what vista start is on the old HDD. Using the installation DVD I can get up the command prompt and run Bootrec.exe without the old HARD disk installed, which can find the vista installation, but fails to solve the problem. I'm not an expert so I can't properly use Bootrec.exe, and startup recovery also does not work, although it seems to say that something to do with the startup has been fixed. Is it possible that I can get the computer running without the old HDD without having to reinstall vista on the new hard drive? Currently, I put the old HARD return drive to start the new installation of vista.

    When you move an old hard drive to a new computer, the installed operating system will find new hardware (motherboard, etc.).

    A clean install is a normal requirement, as no drivers are installed for the new hardware on the operating system.
    Thus, it will not start.

    How to do a clean install:

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

  • How to remove the Firefox disk icon

    I uninstalled Firefox last week because I had problems with computer (fans) after the last update. Just a coincidence I think because I continued to have the same problems after uninstalling, so I reinstalled it today. However, I'm unable to remove an orange square drive? my desktop icon. I can only take it off if I leave Firefox. After opening Firefox again, I not only to get the icon back, but I also get training install area once again, that is to say... big box with blue and orange Firefox icon dictate to put in my file of the application. If I do this, Firefox re - install once again, and I start over. I restarted my computer hoping that would be useful, but it did not. If it's harmless, ok, but he was never there for the many years I have used Firefox and it's a pain to have to click on the box and also have the icon on my desktop, all the time.

    You're clicking on the stub Installer to launch Firefox after that you already installed. Please remove any installer stub after you have already added the icon in the Applications folder.

    You can then pin it to your doc so that Setup of heel will no longer launch icon.

  • Copy the old Time Machine files to the new disk TM

    Sorry people, I have to ask two (related) questions:

    (1) I have a WD My Passport for Mac drive connected to an Airport Extreme and 2 Macs use for backup via Time Machine. Now, the disk is full. I bought a WD My Book for Mac drive with a capacity of 4 TB and am ready to go.

    Question: can I copy the old files of Time Machine on my new book?

    (2) until now 2 different Macs used the My Passport as a Time Machine drive with no problems.

    Question: Should I partition the new drive (My Book) and every Mac uses its own partition as Time Machine or can proceed us as is?

    Thank you very much for your help!

    Question: can I copy the old files of Time Machine on my new book?

    Yes you can, but there is a lot of work, a little complicated, time consuming and not worth the effort for most users.  The main reasons for this are...

    (1) the older backups will take a good amount of space on the new drive, limiting the space on the disk again.

    (2) Time Machine backups for the old files will continue... it will make a new copy of every Mac and then go forward again with incremental backups.

    A better plan would be to keep the old drive on hand for a few months, in which case you need to go back and look for a file. After a few months, you will have a beautiful story from backup to the new hard drive and no need of older backups so you can remove the old disk and keep around as a spare part or use it for other purposes.

    Question: Should I partition the new drive (My Book) and every Mac uses its own partition as Time Machine or can proceed us as is?

    While you can partition the drive and save each Mac to a separate partition if you wish, there is really no need to do this since Time Machine will automatically create separate for each Mac backup files.

  • After removing the Dual Boot, I can't delete the old partition

    Some time ago I installed an SSD and I have Windows 7 installed in Dual Boot with the Windows 7 system.
    So, I had two versions of Windows 7, which worked well.

    Now I no longer use the old system, I disabled the function of Dual Boot. I want to format the old drive, but it does not work because Windows still sees it as active system partition. In addition, I can't delete the partition.

    How can I format or delete the old partition?

    I already tried Msconfig, Bud that did not help. Default Msconfig begins with 'selective startup' and an operating system that is displayed in the Startup tab. When I select 'Normal Startup' there are two operating systems that are listed in the Startup tab. When I delete the old and reboot, it is back again...

    Who has the solution?

    (1) create a system repair disc (if you do not have an installation disk for Windows 7 for the version of Windows you have installed).
    http://Windows.Microsoft.com/en-us/Windows7/create-a-system-repair-disc

    (2) then remove the hard disk you want to format. Now try to start the remaining version of Windows. You should see a missing bootmgr message. Proceed to step #3.

    (3) Bootmgr is missing, message or black screen with cursor flashing
    (See method #2 in this Wiki article)
    http://answers.Microsoft.com/en-us/Windows/wiki/Windows_7-system/Bootmgr-is-missing-message-or-black-screen-with/73fef5b7-5a7f-4910-a2b0-7219e9ec1646

    (4) after you have created the BCD store on the remaining drive (to step #3 above), it should start up on Windows and also be the partition 'Active'.

    (5) shut down the PC and set the old drive, turn on a load Windows and then delete all the remaining partitions on the old disk.

  • How do you insert/remove the HDD in the T5500?

    I want to remove and put back in a hard drive.   I don't know how many screws and which screws to remove to do.

    I can't remove the screws more that I need to.  And I see that maybe if I unscrewed the wrong screw then black Assembly will detach the metal grame.

    http://i.imgur.com/Yd70pVl.jpg

    In the photo below, see two screws on top that are fairly close together. I let them ' cos I think they can join the Assembly and I don't want to unscrew the Assembly - the brackets that hold the hard drive, I don't have to

    And to the bottom of the image, you see two screws unscrewed, but the one I found that I could not even remove the hard disk.  And there is a little black thing between them that looks like a screw, but is not.

    I guess I could remove all 4 screws, but then the Assembly could come off.   For now, I just want to remove the hard drive.

    http://i.imgur.com/65fGtgv.jpg

    The album came out without removing ONE screw.

    Lift the blue ejector arm and the drive is kindof pryed out.

    The ejector arms have a PIN that goes into the screw holes to hold the reader in.  Once you raise the Lock ejector you lift a little far and out on this side.  The other side has fixed pins.

  • Merger of the snapshot disks failed

    I tried to delete all the snapshots with the corresponding key of vSphere Client. But in the end, my data store was full. Some view-popup and check if there is enough free space would be great for the future.

    The disk is named as dish (vSphere Client and the file is called disk - flat hard). But the 12G drive is only about 2G of fat. I think that this problem was which extends the size of the disk (previously was a thin disk, it was named after its expansion in thickness). Someone of you did this, also?

    When a correctly created flat disc, is always possible merging without needing extra space?

    The virtual machine still works, so I think that there is no loss of data (only some data is written twice-> in a single vmdk file and a parent). I have a space to another data store. I think that there are vmkfstools on the console hidden ESXi (or SSH). I can use them to create a vmdk file (descriptor of + - flat.vmdk file) to the another data store. Is this possible with the different delta-snapshot files or will it cause problems? Can I then use the unix mv command to move the data store original (after I deleted the old files) or what I need to change the descriptor file, or something similar?

    Thanks for your help!

    Post edited by: darkdragon001

    Reason: snapshots for vmkfstools

    To resolve the situation, I recommend that you create a clone of the disc on the other data store, test it and if it works, you can remove the old disk and copy/move the clone in the original folder.

    -Create a new folder on the second data store (for example ' clone')

    -stop the virtual machine

    -vmkfstools-i /vmfs/volumes/datastore1/YourVM/YourVM-00000x.vmdk d /vmfs/volumes/datastore2/clone/YourVM.vmdk thick

    -create a backup of the current vmx file

    -Open "Edit Settngs" and point the virtual disk on the cloned disk

    -test your virtual machine

    -If everything is ok you can delete files vmdk in the original folder, copy the vmdk cloned in this folder and change the settings of the virtual machine

    In the command "vmkfstools" you must specify the current instant vmdk file as the source. You will find the name of the snapshot in VM settings or in the vmx file.

  • Reconfigure the virtual disk using OpenManage of RAID 0, RAID-5

    I apologize for the spacing.  I'm having a little wrong with this forum edit my post.

    My small business has had a T610 run for a few years with the following configuration:

    T610 Server

    PERC 6 / i controller

    4 physical disk 1 TB

    Virtual disk 0 size 1 800 GB RAID - 5

    Size of the virtual disk 1 992 GB RAID - 5

    Virtual Disk 1 was running Exchange and everything else on VD 0.

    Last weekend, I had a breakdown of table flat due to the failure of a damaged drive on Windows SBS 2008, who couldn't recover. When I contacted support Pro and got a new drive, I was told not to recreate the same virtual drives and use one.

    The local tech and I have been quite underlined and used the Perc 6 / I BIOS to recreate the exact configuration. Then, we had to use Backup Exec 2010 to restore the data. Somehow, we have selected by mistake instead of RAID 5 RAID-0 on recreation of the two virtual disks.

    So now, I have the following configuration in OpenManage:

    Virtual disk 0 size 1 800 GB RAID - 0

    Size of the virtual disk 1 992 GB RAID - 0

    I called Dell and gave instructions in OpenManage on how to reconfigure a virtual disk by adding a physical drive and conversion to RAID-5. My problem is reconfigure is not an option in the dropdown menu, I am told, because I have two virtual disks that have stripes.

    I have the ability to drive to go to 1 single virtual disk, given only Exchange is on the second and I can move, then unmold Virtual Disk 1. So my plan is:

    Full backup tape.

    Move Exchange off the drive sitting in virtual disk 1 to disk on virtual disk 0.

    Remove the virtual disk 1.

    Add a 5th physical HD.

    I hope at this point OpenManage will then give me the option in the drop-down list to reconfigure Virtual Disk 0.

    The option to Reconfigure in OpenManage will appear after that he sees only 1 virtual disk?

    Hello

    KRoy66
    The option to Reconfigure in OpenManage will appear after that he sees only 1 virtual disk?

    Yes, the ability to reconfigure should be available as soon as you remove the second table off readers. Technicians are you talked with correct you cannot reconfigure a table in slices.

    I know that you went through the entire process of relocation and restoration of backup, but it is preferable that do you it again. Let me explain why your table has been configured in this way, and why you may need to reinstall again.

    There are limits on the partition. To create a partition more of 2 TB, it must be TPG. In order to boot the system from a partition GPT Board must be set to UEFI mode. The problem you will encounter when trying to create a large RAID 5 is that you will not be able to use more than 2 TB of it. You create a new table in slices to use the extra space.

    If the system card is already set to UEFI mode then you should be able to convert the GPT partition and expand to necessary to hold account space. If you have installed the operating system with the system of administration established on the MBR can change in UEFI and conversion of GPT likely to cause BONE to be unstable if you are able to boot on it at all.

    I think you need to save yourself a lot of hassle and do this upgraded correctly. I know it will be a lot more time to restart, but you should set the UEFI boot mode, remove the two RAID 0, create the new large RAID 5, reinstall the OS and then restore the backup.

    Do it right now probably will save you a lot of time.

    Thank you
