About troubleshooting automatic import jobs

The automatic import jobs that the storage lifecycle policy (SLP) components manage are different from legacy import jobs. Automatic import jobs asynchronously notify NetBackup that an image needs to be imported. Also, Auto Image Replication jobs provide catalog entries to the storage device so that the job does not have to read the entire image. An automatic import job reads the catalog record off the storage device and adds it into its own catalog. This process is so fast that NetBackup batches images for import for efficiency. A pending import is the state where NetBackup has been notified, but the import has not yet occurred.

More information is available about the import operation in an SLP and how to tune the batch interval of the import manager process.

See the NetBackup Administrator's Guide, Volume I.

The notify event from the storage server provides the following: the image name, the storage server location to read the catalog for this image, and the name of the SLP that processes the image. Images for automatic import jobs are batched by storage lifecycle policy name and disk volume. The import job consumes an input-output stream on the disk volume.

To view the images that are pending import, run the following command:

# nbstlutil pendimplist -U

The action to take on the automatic import job and the automatic import event depends on several conditions as shown in the following table.

Action

Condition

Automatic import jobs queue

No media server or I/O stream is available for this disk volume.

Automatic import jobs never start (copy stays at storage lifecycle state 1)

  • The storage lifecycle policy is inactive.

  • The storage lifecycle policy import destination is inactive.

  • The storage lifecycle policy is between sessions.

  • The image has exceeded the extended retry count and the extended retry time has not passed.

Automatic import event is discarded and the image is ignored

  • The event specifies a backup ID that already exists in this master server catalog.

  • The event specifies a disk volume that is not configured in NetBackup for this storage server.

Automatic import job is started but the image is expired and deleted to clean up disk space in some cases. The event logs an error in the Problems Report or bperror output. An import job runs, but the import for this image fails showing a status code in the range 1532 - 1535.

  • The storage lifecycle policy that is specified in the event does not contain an import destination.

  • The storage lifecycle policy that is specified in the event has an import destination with a residence that does not include the disk volume that is specified by the event.

  • The storage lifecycle policy that is specified does not exist. By default, the Storage Lifecycle Policies utility automatically creates a storage lifecycle policy with the correct name. Ensure that a storage lifecycle policy with the same case-sensitive name exists in the target master server.

    More information is available for the storage lifecycle policy configuration options.

    See the NetBackup Administrator's Guide, Volume I.

Look at the Problems Report or the bperror list for these cases.

To troubleshoot the job flow for automatic import jobs, use the same commands as you would for other storage lifecycle policy managed jobs. To list images for which NetBackup has received notification from storage but not yet initiated import (either pending or failed): use the commands that were previously noted or run the following command:

# nbstlutil list -copy_type import -U -copy_incomplete

To list the images that have been automatically imported, run the following command:

# nbstlutil list -copy_type import -U -copy_state 3 -U

The OriginMasterServer here is not empty, although it may be in some cases. In cascading Auto Image Replication, the master server sends the notification.
