Error description
Error Description: During a full backup, IBM Tivoli Storage Manager for Mail Data Protection for Microsoft Exchange fails to inactivate incremental legacy backups of Exchange databases when the number of objects eligible for inactivation exceeds the value of the TxnGroupMax option. This problem occurs with API 6.3.x and higher. VSS backups are not affected by this issue. Note: The TxnGroupMax option is defined on the Tivoli Storage Manager server for the node that performs the backups. Tivoli Storage Manager Versions Affected: All versions of Data Protection for Microsoft Exchange which use API level 6.3.x or higher Other Affected Products / Components: All versions of Tivoli Storage FlashCopy Manager for Microsoft Exchange which use API level 6.3.x or higher. Customer/L2 Diagnostics: This problem can be verified by querying the Data Protection for Microsoft Exchange backups information. On the Data Protection for Exchange side, you will see incremental backups with no associated full backup. On the Tivoli Storage Manager server side, you will find that those same incremental objects do not have DEACTIVATION_DATE. These should show a date which reflects the full backup that deactivated the full it was bound to. Initial Impact: Medium Additional Keywords: tdp tdpexc incr expire
Local fix
Increase the value of the TxnGroupMax option for this node on the TSM Server. 1. From the Tivoli Storage Manager server command line issue: q node NODE_NAME f=d and take note of the current value for the Transaction Group Max Note: The NODE_NAME will be the node associated with the Exchange backups, not the localdsmagent. 2. Update txngroupmax for this node with a new value: update node NODE_NAME txngroupmax=65000 3. Run a FULL backup of the databases. The orphaned incremental objects will be deactivated and will follow the current retention settings. 4. Restore the initial value of the TxnGroupMax option (from step 1).
