Issue

Backups failing with network error messages writing to remote tape library after CommVault SP Upgrade.

Tue May 26 07:03:40 PDT /SVM/VOLUME/Backup BKP-Info (replication_sender_error=25) Wed May 27 14:01:11 PDT /SVM/Volume/ BKP-Abort (SMTape Backup: Message from Write Dirnet: Interrupted system call)

These errors indicate a failure to send data over the network due to a failure to write to the tape(s) library downstream.
