Recently, a customer has informed me, that copy sessions to encrypted devices failed, after he has made an update to Data Protector 9.07. The copy sessions failed with this error:
|Critical| From: [email protected]<hostname> "" Time: <Date><Time> |90:6111| Error retrieving encryption key.
The customer uses tape encryption. The destination for the backups is a HPE StoreOnce, and a post-backup copy creates a copy of the data on tape. Backup to disk was running fine, but the copy to tape failed immediately.
The customer has opened a ticket at the HPE support and got instantly a hotfix to resolve this issue. HPE has documented this error in QCCR2A69192. If you run into the same issue, please request hotfix QCCR2A69802. This hotfix consolidates QCCR2A69192 and QCCR2A69318 (The BMA ends abnormally during backup/copy to tape).
Thanks to Stefan for the hint!
