    Got a question for you 2105 gurus...

    I have a 2105-F20 SCSI attached to several servers. I have several "hosts"
    defined. I want to add additional hosts because some of the hosts have
    multiple connections, and the connections have different VGs assigned.

    For example:

          HostA has 4 connections, 2 to one VG, 1 to another VG and 1 to the
    final VG.

    I want to change it as follows:

          HostA_VG1 has 2 conenctions
          HostA_VG2 has 1 connection
          HostA_VG3 has 1 connection

    Can I take the existing assignments and reassign the storage to my new host
    definitions without losing data? This makes allocating LUNs easier,
    because I don't have to look and see what VGs are on the SCSI ports at the
    Shark. I can know by the "host" name exactly where to allocate additional
    LUNs.

    Thanks, Bill.
