Reusing FlashCopy Logical Drives: Additional Information for Solaris – VERITAS Volume Manager

Typically, after a has been created, it is disabled until a new point-in-time image of the same base logical drive is required. Use this procedure to create a new point-in-time image of the same .


Important:

Stop all activity to the base logical drive at this point (or data transfer suspend) to make sure that an accurate point-in-time image of the base logical drive is captured.

  1. Unmount the disk representing the base logical drive and the disk representing the flashcopy logical drive. At the host prompt, type this command, and press Enter:

    unmount mount-point
    

    In this command, mount-point is the name of the disk being unmounted.

  2. Perform a synchronize operation to make sure that all previously unwritten system buffers are flushed out to disk, which makes sure that all file modifications up to that point will be saved. At the host prompt, type this command, and press Enter:

    sync
    

    All unwritten system buffers are flushed.

  3. In the storage management software, re-create the flashcopy logical drives by using one of these methods:


    Note:

    If your plex spans across a number of , make sure that the procedure repeats for each storage subsystem.

  4. In the VERITAS Volume Manager System Administrator, mount the file system that is associated with the disk group by selecting the file system associated with the disk group, and right-clicking and selecting Filesystem >> Mount .
    The disk groups that are associated with the file system are mounted.
  5. On the host where the flashcopy logical drive resides, make sure that the file system was mounted correctly. At the host prompt, type this command, and press Enter:

    df-k
    

  6. Use the flashcopy logical drive with your backup application (or another application).
  7. After the flashcopy logical drive is no longer required, disable the flashcopy logical drive.

    If you disable the flashcopy logical drive instead of deleting it, you can retain the flashcopy logical drive and its associated flashcopy repository logical drive. Then, when you need to create a different flashcopy of the same base logical drive, you can re-create the disabled flashcopy logical drive. This action takes less time than creating a new flashcopy logical drive and stops any reduction in performance that might occur if the flashcopy logical drive remains available.
