Dual path with DPM and Tape library issue RRS feed

  • Question

  • DPM server has dual port HBA going to 2 fabrics. Library has a single drive and dual library ports to both fabrics.

    With one library cable, it works fine but to cable both library ports, DPM identifies the same device twice.

    HP MPIO software installed but we had to disable the MPIO services and reboot to get it back to having just one port working.

    Can DPM handle a dual path library?

    If it can, how might i fix this?

    thanks

  • Hi,

    You should never have a device exposed twice to the server without MPIO software installed.  Fix the MPIO software so you have redundancy for the fabric.
