Try looking at the BPTM and BPDM logs (T for Tape, D for Disk). I don't know if a VTL will go to TM or DM...I would assume TM since NBU thinks it's a tape still.
Sounds fishy since it changes drastically after the second 'tape' is mounted. Have you searched to see if there is a known issue?

I've noticed that when i start a job it jumps right up and the speed is 25MB - 40MB then after the "tape" fills and a second one is "loaded" the KB/Sec drops to 2MB - 4MB and the speed never raises for subsequent "tapes". However when I write directly to LTO5 the jobs average 40MB - 60MB. Using an EMC Clarion VTL. Any advice would be greatly appreciated. Is there a log in NBU that would indicate these write speed fluctuations? Any thoughts would be greatly appreciated. +---------------------------------------------------------------------- |This was sent by nmagsay...@gmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +---------------------------------------------------------------------- _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
