    Hello,

    This may need some investigation though .. would like to understand some basics ..

    1. what is OS & SF version ?

    2. Is array configured as per recommended settings in HCL ?

    have you had a look at HCL below: (taking SF 5.1 in consideration)

    http://www.symantec.com/docs/TECH74012

    There is a firmware level mentioned for VSP array, does your array have that firmware level ?

    3. Read out  http://www.symantec.com/docs/TECH47728  

    Above article talks about Host and Storage Configuration Guide for DMP. Have a look at page 23 for VSP array settings which veritas recommends ...

    for e.g for solaris

    Solaris
    50-07-66-00 (USP/NSC)  >>>>>>>>>>>>>> min. firmware level
    09 (Solaris) >>>>>>>>>>>>>>>>>>>>>>> Host mode
    02 (Veritas Storage Foundation for Oracle Rac), 22 (Veritas Cluster Server)  >>>>>> host mode options
    A/A >>>>>>>>>>>>>>>>>>>>>>>>>>>>> DMP Failover mode ..
