    Admins:

    I need your advice in approaching a SAN Upgrade next
    weekend in our environment. I have several 8400s,7410s
    and Superdomes with redundant HBAs connected to the
    SAN Storage Units. I have checked that all the servers
    have Primary and Secondary Links. The SAN guys are
    upgrading the TOP FABRIC one weekend and the BOTTOM
    FABRIC the next weekend.

    We are expecting a change in cXtYdZ numbers. My plan
    is to move the primary/alternate links with pvchange.
    That way I will minimising the downtime and the users
    can use the Filesystems with only one path. Can anyone
    advice me/guide me with the lessons they learnt with
    something similar
