    Hello all,

    We are needing to move some data from one lun to another lun on our SAN.
    Let's say the source is drive U: and the target is drive X:

    After we copy the data to fron U: to X: we need to change the drive letter
    on X back to U:. This sounds simple but I would think drive signatures would
    prevent this? Or is just as simple as copy data to X: change the drive U: to
    a different drive letter then change X: to U:?

  2. Dear Customer,

    Thank you for posting in newsgroup.

    According to the description, the issue seems to be related to changing
    drive letter of the LUNs. If I have any misunderstanding, please feel free
    to let me know.

    Yes. It is simple as you can copy data to X: drive, and then change the
    driver U: to a different drive letter and then change drive letter X: to U:
    The drive signatures wouldn't prevent this operation. The only thing we
    need to notice is that we cannot assign the drive letter which is already
    occupied by other driver.

    Hope it helps.

    One more question. What is the best method to do the file copy? Drag and drop
    or should I use xcopy from the command prompt? Or are there other better
    methods? I need to keep the perssions for the files and directories.

  6. Hello Steve,

    Thanks for the reply. According to the description, my understanding of the
    further question is that: you want to know what is the best method to
    perform file copy the files and folders from drive U: to drive X: while
    keeping all the permissions.

    Based on the research, "Drag and Drog" cannot preserve the permission
    settings. I would like to suggest that you use the "robocopy" utility to
    copy files and folders from drive U: to drive X: and it can preserve the
    NTFS permission.

    Here is an example just for your reference.

    Example:
    =============

    Ex. "robocopy U: X: /e /sec"

    /e: Copies subdirectories. Note that this option includes empty directories.

    /sec: Copies files with security

    Please ensure the local credential that you logon has the permission to
    read source directory and the create files on the target.

    For more reference, please refer to:

    Robocopy

    a-9d04-2d8c367b63541033.mspx?mfr=true

    Source of Robocopy:
    =====================

    1. For Windows Server 2003 operation system, we need to install the Windows
    Server 2003 Resource Kit Tools, which includes the robocopy utility.

    You may download the Windows Server 2003 Resource Kit Tools from the link
    http://www.microsoft.com/downloads/details.aspx?familyid=9d467a69-57ff-4ae7-
    96ee-b18c4790cffd&displaylang=en

    2. For Windows Server 2008 operation system, the robocopy utility is
    already built in the system, we may run it in the command prompt directly.

    Hope this information will be helpful.

  7. if doing a copy, with ROBOCOPY it does not copy over what already has been
    copied in a previous run (assuming the correct switches here). Sometimes you
    need to do multiple runs because the file copy stops, or the source is
    updated, etc

    Actually I do have another question. I have been looking at RoboCopy. Seems
    like a very good utility. I have a question about the syntax. You gave me an
    example of

    robocopy U: X: /e /sec

    I was wondering if I could accomplish the same with :

    robocopy U: X: /copyall

    or does this not acheive the copying all files and directories with all
    security and attributes?

    I was actually playing with :

    robocopy U: X: /e /v/ /s /copyall /R:10 /W:30

    But I think that may be overkill. Can you advise?

    Thank you.

  12. Hello Steve,

    Yes. You may accomplish the task with the command. And it will copy all
    files and directories with all security and attributes

    "robocopy U: X: /copyall"

    The above command is equivalent to "robocopy U: X: /copy:DATSOU"

    For your reference, I have list the syntax of /copy:DATSOU as followed.

    D: Data
    A: Attributes
    T: Time stamps
    S: NTFS access control list (ACL)
    O: Owner information
    U: Auditing information

    Based on the research, it is recommended that you not run the following
    command with the syntax /e /s concurrently.

    robocopy U: X: /e /v/ /s /copyall /R:10 /W:30

    /s :excludes empty directories

    /e: includes empty directories

    You may run the command separately according to the actual system
    environment.

    Hope it helps.

    Are there any special considerations needed for copying SQL files? Or does
    Robocopy treat SQL files as any other file type?
     
    Steve, Jul 21, 2008

  14. Hello Steve,

    For the files about the SQL server, you can treat them as any other file
    type with robocopy.

    Hope it helps.
