Hi - we have 2 sites , one a W2K3 (SP1) storage node with a MSL5026 library , and the Legato W2K3 standard server with a MSL5052 library. Both libraries have 2 sdlt320 tape drives. The drives attached to the server show 128K block size, but the storage node devices are only 64K. Tapes written via the server cannot be read on the storage node device if we lose the other library. I have run scanner on such a tape and it fails immediately. What should I be looking at to get the storage node devices configured the same as the server devices? BTW these are both SAN attached -

 fiber switched etc.
