Configuration: TSM V 5.2 OS = Aix 5.1 3584 Library (latest Firmware) 2 Fibre Switches (4 LTO GEN 1 Drives Each) 8 LTO GEN 1 Drives 2 Fibre Cards Switch 1 (Drives 1234) Switch 2 (Drives 5678)
I just recently Added 2 new LTO Tape Drives to my 3584 Library. In doing this I had to add a new switch and decided to split the load on the switches to help throughput. In doing this I had to delay my backup stgpool jobs so that is currently running. In order to catch up on time I thought why not use the new drives. I Issued the command backup stg (Onsite Tape Pool) (Offsite Tape Pool) maxpr=3. Now the backup is running really slow if the process has tapes mounted on switch 1 and 2. If they are on the same switch they run fine. Am I missing some type of configuration here or something? Please assist as I was sold this as being a faster solution and then sold it to my Sup's as a faster solution. If more info is needed please let me know.
