Error description

  • A fix was needed to handle DS8000 8 port support when
    establishing from a DS8000 with 4 ports.
    This scenario requires special handling for path support on a
    target with 8 ports in order to establish paths.
    This special handling does not take in to consideration other
    vendors that do not require the special handling for more than 4
    ports at the target.
    
    Introduced when we fixed IT01752 in TPC 5.2.3.
    

Local fix

  • Please contact support for workaround.
    

Problem summary

  • | fix pack | 5.2.5-TIV-TPC-FP0000 - target 1Q 2015 |

    The target dates for future fix packs do not represent a formal
    commitment by IBM. The dates are subject to change without
    notice.
    
    Users who have Hitachi or EMC devices connected via zOS
    attachment who are starting a MM or Hyperswap session for the
    first time or trying to establish a path will fail because TPC-R
    is attempting to address an issue specific to DS8000
    compatibility of 4 port (on pre 8300 devices) to 8 port fiber
    channel cards. This causes the path establishment to fail on
    Hitachi and EMC because these devices do not have a requirement
    for special handling - but the special handling is applied
    anyway  without checking the device manufacturer.
    

Problem conclusion

Temporary fix

  • as a workaround and to prevent the issue from occurring, you can
    set the minimum code level required for this special handling to
    lower than the code level in the Tivoli Storage Productivity
    Center for Replication rmserver.properties file by adding the
    following property to the file:
    
    com.ibm.csm.server.hw.lic.ess.EightPortFeatureCodeService.MinCod
    eLevel=0.0.0.0
    
    This rmserver.properties file is in the following directory:
    
    Tivoli Storage Productivity Center for Replication:
    WAS_HOME/profiles/ReplicationServerProfile/properties
    Tivoli Storage Productivity Center for Replication for System z:
    WAS_HOME/profiles/ReplicationServerProfile/properties
    
    *Note that if  this setting is in place then path creation will
    fail when trying to establish a path between a DS8000 storage
    system using 4 port adaptors to 8 port adaptors.
