Symptoms

NDMP backups are failing on the Oracle ZFS Storage Appliance. The backup application is Commvault.

The ZFS-SA has a HBA installed, with a number of tape drives presented to it via the SAN.

The tape drives appear in BUI Status/NDMP.

Most filesystems are backed successfully, but many are unsuccessful. When the unsuccessful filesystems are backed up individually, they will usually backup successfully.

This is the relevant information from the Commvault logs:

02.10.2015 - 10:56:28 - Backup begins
02.10.2015 - 10:58:03 - Tape (barcode MC0285L6) loaded
03.10.2015 - 08:09:13 - error writing chunk trailer to media (these are the errors that Simpana seems to get when it hits an issue writing that file system out to tape)

03.10.2015 - 08:38.42 - Backup completes

The ZFS-SA NDMP log shows:
