I have 2 dual port 6Gbps SAS HBAs installed in a 2950 connected to a TL4000 with 4 LTO5 drives. Each port on the SAS cards attaches to a different tape drive but my backup software only sees 2 drives available. Why?
First thing is what backup software are you using? Second in the PE2950 are both 6gb sas cards in the 2 8xPCIe slots? Also is your TL partition as more than 1 or is it just using a single partition? Are there any error on the TL4000?
Please let us know if you have any other questions.
