     I assume you mean IBM Enterprise Storage System(shark/ESS f20/800/ds8x00)

    1. You can not use RDAC and SDD together on the same HBAs, so the first
    thing that needs to happen is you need to either add HBAs for ESS
    attachment, or eliminate some HBAs from RDAC attachment and rededicate for
    ESS attachment.
    2. Once you've resolved the issue from step 1, and you have a physical
    connection to the ESS, and the switches are properly zoned, you will need to
    present LUNs from the ESS to the hosts.
    3. migrate (assuming aix) using migratepv, mklvcopy, or whatever other
    method you choose.
    4. if necessary remove the FASTt disk (then you can re-use the RDAC HBAs)

    this is obviously a 10,000 ft view of the migration, but this should get you
    started.

      Hi experts,

      Does anyone have steps or excel *** format if we plan to migrate from
    existing storage FASTt500 to IBM Enterprise Storage Manager.

      Any help is really appreciated.

      Regards
