About Auto Image Replication import confirmation
When using targeted Auto Image Replication (A.I.R.), storage lifecycle (SLP) processing of each replicated image is paused in the source domain until a message has been received from the target domain that confirms that the image has been imported successfully. SLP processing does not continue for the image until the confirmation occurs. Import confirmation ensures that source domain images remain in place at least until those images have been safely imported in the target domain.
In the source domain, NetBackup keeps track of image copies that remain in import pending state for more than 24 hours. Whenever such images exist, NetBackup generates a message in the Problems report. This message indicates that import-pending images are present. You can configure a different time threshold for generating a confirmation message. You can also configure an email address to receive the same information send to the Problems report.
If you receive notification that images are in an import pending state, you can run the nbstlutil command. This command generates a report that provides details of those images. You must then investigate the cause of the import problem and address any issue that you find. The import-pending state is automatically updated when the imports are completely successfully. Alternatively, you may decide that import operations in the target domain are no longer needed, and you can then cancel SLP processing for those images in the source domain. This action also clears the import-pending state, but no further SLP processing happens for those images.
See the NetBackup Commands Reference Guide for details about nbstlutil.
Note:
A.I.R. operations require that a trust relationship be established before configuring and operating SLPs that perform targeted replication. In NetBackup 8.1.2, 8.1.1, and 8.1, these operations include import confirmation messages that are sent from the target domain to the source domain. Security changes that were added in NetBackup 8.1 require that this trust relationship be re-established before import confirmation can proceed.
Import confirmation operations are not enabled by default in NetBackup 8.1 or 8.1.1, regardless of whether the system is upgraded to NetBackup 8.1 or 8.1.1 or an initial install of 8.1 or 8.1.1 is performed. Refer to the following tech note for information about enabling the A.I.R. import confirmation feature in NetBackup 8.1 or 8.1.1:
