Error description

  • Sometimes, if an erratt occurs on the adapter during
    failover/
    failback, PLOGI to remote target may not complete fully
    and
    all further IO directed down that path may fail.
    
    There will be RELOGIN Timeouts logged:
    
    LABEL:          FCP_ERR4
    IDENTIFIER:     4B436A3D
    [...]
    
    Detail Data
    SENSE DATA
    0000 0010 0000 0029
    [...]
    
    along with FCA errors of the following kind indicating
    adapter
    ERRATT:
    
    
    LABEL:          FCA_ERR2
    IDENTIFIER:     D666A8C7
    
    [...]
    
    Detail Data
    SENSE DATA
    0000 0010 0000 0051
    [...]
    
    and
    
    LABEL:          FCA_ERR2
    IDENTIFIER:     D666A8C7
    
    [...]
    
    Detail Data
    SENSE DATA
    0000 0010 0000 0030 0302
    
    [...]
    
    The path will then not recover unless the adapter is
    reconfigured.
