    ****************************************************************
    * PROBLEM DESCRIPTION:
    * After using chdev to clear a pv (pv=clear) on a SAS RAID
    * Array, cfgmgr will clear the PVID value when it is next run
    * (even when the disk is available).  This can cause loss of
    * data in block 0 of the disk when the disk is used as a raw
    * device.
    ****************************************************************
    * RECOMMENDATION:
    * Install APAR IZ74810.
    ****************************************************************
    

Problem conclusion

  • During configuration (cfgmgr), do not check the pv attribute
    for any pending pv operations such as pv=clear when the disk
    is already in the Available state.
