Restore of MPX backups to tape fail after Solaris SPARC master server upgrade to NetBackup 8.3 (Etrack 4019326)
Abstract
Description
Veritas Bug ID: ET 4019326
Version: NetBackup_8.3
Problem Description:
Corrected a defect in nb/dblib/dbimageq.c where the MpxState field of DBM_ImageCopy table is incorrectly decoded as a short integer instead of integer. On Solaris Sparc this fails to convert properly and the MPX value is 0 instead of 1. This MPX value makes its way into the image database for MPX tape backups. The backup copies have correct backup headers. If those tape backups are duplicated to tape again, the backup headers on tape are incorrect.
Version 2 adds the following:
The bptm binary was modified to fail a read of an image where the data-stream doesn't match the MPX setting of the reader. Without this change, the duplicated copies of these images are corrupt.
