Multi path Support for Tape library -
Ursache
NVBU does not support multipathing to a tape library or device, so only one channel should be logically or physically configured for use to ensure consistent communication path

Lösung
Tape Device Multipathing configurations are typically Active-Passive in nature and most certainly requires I/O interruption. In addition, unless there is a driver provided an OEM vendor, an automatic failover is not possible. Most Operating Systems will provide separate device files for the same devices which are detected over different paths. These individual paths must be manually reconfigured when failover and failback occurrences need handling. This implies that most backup and restore operations will fail during a failover or failback situation and will require restarting the job and respective data transferNVBU does not support multipathing to a tape library or device, so only one channel should be logically or physically configured for use to ensure a consistent communication path.
However, an Enhancement request number (NVBU-16471,DNNDMP-739) has been submitted to Development for consideration in a future release of Netvault.
