The backup server installed with the NetBackup6.5 and MS iSCSI initiator 2.05 is connected to the VTL3605 through the iSCSI. When you perform backups, some succeed but some not, and backup software shows the error information "media write error".
Step 1 Uninstall MS iSCSI initiator 2.05 and install MS iSCSI initiator 2.08.
Step 2 Restart backups
Backup software NetBackup6.5 and MS iSCSI initiator 2.05 are incompatible with the VTL3605. When one tape is used up and no new tape replaces it, the backup fails.
