Hi, There are two VTL HBA ports. One of them should be set to initiator mode while the other should be set to target-mode. This will help segregate tape and disk transfers. The mode can be changed from the GUI "Access Management" page. Under "Target Port Configuration" for one WWPN click on Modify and select Initiator and for the other WWPN select "Target" The switch zoning can be changed appropriately to allow access for the hosts to only the target mode WWPN.
>From one of the drive statistics write_bytes_processed: 1335859200 write_cmds: 260910 This is an average of 5120 bytes per command which is very small. There were other backups but it looks like the system was restarted and this was the only backup for which we have stats maintained. Which backup application is used to copy files from the linux partition ? Is LTFS being used ?
