Summary
This article outlines the specific requirements of tape device ID usage in Data ONTAP 8.1.x.
Symptoms
After upgrading a NetApp storage system from Data ONTAP 7.3 to 8.1.1, the local tape drives no longer functions with NSB. The device is a SAN attached NEO8000e tape library with 10 HP Ultrium LTO4 drives.
The NDMP backup to the local device path returns error RC 1104.
The job log displays the following messages:

Resolution
In the NSB management console, navigate to Configuration > Devices for each device path or SAN device path definition associated with the NetApp storage system running Data ONTAP 8.1.x. Change the definition from /dev/nrst#a to nrst#a.
