Publication Date:  2015-07-29 Views:  320 Downloads:  0

Issue Description

A template file is created on the Oracle database server and is backed up. The backup fails and the following error message is displayed:

INF - RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
INF - RMAN-00571: ===========================================================
INF - RMAN-03009: failure of backup command on ch00 channel at 02/16/2012 13:09:38
INF - ORA-19506: failed to create sequential file, name="bk_u0rn3fbfp_s27_p1_t775400953", parms=""
INF - ORA-27028: skgfqcre: sbtbackup returned error
INF - ORA-19511: Error received from media manager layer, error text:
INF -   VxBSACreateObject: Failed with error:
INF -   Server Status: no storage units available for use
INF - Recovery Manager complete.
INF - End of Recovery Manager output.
INF - End Oracle Recovery Manager.

Handling Process

1.  Log in to the NetBackup Administration Console on the master server as the root user.

2.  Double-click the backup policy. Select an available storage unit or Any_available in Policy storage in the Attributes window.

Root Cause

The storage unit selected based on the backup policy is unavailable.


If the location for storing backup data is not specified, you can select Any_available. The system automatically selects an available storage unit to store the backup data. In this way, the probability of data backup failure due to unavailable storage units is minimized.
