Setting Migrate Default Destination Options

Migrate Destination Options control how writes files during a Migrate operation.

To check the default migrate destination options or edit default migrate destination options:

1. Open the Configure Defaults window by selecting Configure from the Function Tab bar and clicking Defaults.

2. Expand the Manage Tape - Migrate options.

3. Click the Destination icon or name to select it. The selection is indicated by the selection check box next to the option icon, and the Migrate Destination Options dialog appears.

4. Optionally enter or revise each field:

• Tape Usage

  Determines whether or not to accept a tape with data on it.

  Use a new tape	Requires media with status New or Empty from the selected media pool. Media with status New is only be used if the option “Unlabeled Tape Usage” (defined below) is set to “Allow unlabeled tapes and label them.”
  Attempt to append data to available tape	Accepts a backup tape from the selected media pool with data on it (status Appendable) and writes to the unused portion of the tape. The appended data can have a retention period that differs from the data preceding it on the tape.

• Unlabeled Tape Usage Determines expected behavior when an unlabeled tape is found in the tape drive.

  Label unlabeled tapes	Label the unlabeled tape. This saves the step of labeling a tape beforehand.
  Reject unlabeled tapes	Do not use the unlabeled tape.

• Mark Original Offsite

  Determines if a backup tape is stored offsite. DPX adds the Offsite status to the tape.

  Yes	Indicates in the Catalog that the tape is stored offsite.
  No	Indicates in the Catalog that the tape is stored onsite.

• Append Offsite

  Determines if a backup tape with status "Offsite" can be appended to.

  Yes	Tapes in the library with status “Offsite” can be appended to. The Append Offsite field on the Edit Media Pool dialog must also be set to “Yes.”.
  No	Tapes in the library with status “Offsite” can not be appended to.

  The Offsite status of a tape can be viewed through the Operate Tape Library function, the Configure Media function, or in the media volume report. Note that when you use the Operate Tape Library function to import a tape with status Offsite, the Offsite status is cleared and the tape is available for use.

• Mark Twin Offsite

  Indicates in the Catalog the location of twinned tapes, if twinning is on.

  Yes	Indicates that the twinned tape (second tape) is stored offsite.
  No	Indicates in the Catalog that the tape is stored onsite.

• Tape EOJ Usage

  Determines what to do with the tape when the backup job is complete.

  Rewind Tapes	For a standalone tape device, this option rewinds the tape and leaves it in the drive. For a tape library tape drive, this option rewinds, unloads, and returns the tape to its slot.
  Unload Tapes	For a standalone tape device, this option rewinds the tape and ejects it from the drive. For a tape library tape drive, this option rewinds, unloads, and returns the tape to its slot. For DiskDirectory, this option causes empty volsers to be used before new volsers.
  Leave Tapes	For both standalone and tape library tape drives, this option leaves the tape wound to the point where the job ended and leaves it in the drive. The next job attempts to use the tape in the drive instead of mounting a new tape. In the case of standalone drive, if the currently mounted tape is unacceptable (for example, if the next backup requires a tape from a different media pool), the operator is prompted to mount another tape. In the case of a tape library, if the tape in the drive is rejected for any reason, it unloads the tape, returns it to its slot, and proceed to select another tape.

• Max Devices (Devices) Limits the number of storage devices valid for use with this job. Use this option if you want to stop DPX from using all the drives in the selected device cluster so that some drives will be available for other purposes.

• Min Devices (Devices) Holds tasks within a job until the number of drives specified are available for each task to use.

• Tape Mount Attempts The maximum number to check a tape in a standalone tape device.

• Mount Interval (Seconds) The number of seconds to wait between checking the availability of a tape in a standalone tape device.

• Early Device Release

  Controls tape drive usage.

  Select Yes to release the tape drive after the current task with a tape drive finishes so that the next job can use the same tape drive before completing the entire job.

  Or, select No so as not to make the tape drive available for the next job until the entire job completes.

  • Expire Source Tapes

    Determines whether a source tape should expire at completion of job.

  Yes	Indicates source tape(s) expire when job completes.
  No	Indicates source tape(s) do not expire when job completes.

  • Set Retention On The Basis Of

    Determines the basis for calculating destination tape retention.

  Tape	Indicates that all jobs on the destination tape that were part of this operation will expire on the same day as determined by the “Set Retention (Days)” Option.
  Jobs	Indicates that retention period for all jobs on the destination tape that were part of this operation will be increased by the same number of days as determined by the “Increase Retention (Days)” Option.

  • Tape Retention (Days)

    Determines the retention period for all jobs on the destination tape that were part of this operation. Enter a number of days

    • representing the retention period, if Tape was selected as the basis.

    • representing the number of days by which the retention period should be increased, if Jobs was selected as the basis.
