APAR status

  • Closed as program error.

Error description

  • Some commands may hang, and paths fail after the
    following sequence of errors is seen in the AIX error
    log:
    
    FCA_ERR2 with sense data showing error 0x30 in the first
    line of sense data
    SENSE DATA
    0000 0011 0000 0030 ....
    followed by
    FCA_ERR2 with sense data showing error 0x51 in the first
    line of sense data
    SENSE DATA
    0000 0011 0000 0051 ....
    FCA_ERR6 with sense data showing error 0xC4 in the first
    line of sense data
    SENSE DATA
    0000 0011 0000 00C4 ....
    
    The problem applies to physical adapters in both
    standalone AIX hosts and to VIO servers.
    If the physical adapter is mapped to virtual adapters on
    an NPIV client, the NPIV client will lose access to
    the paths on this adapter.

Local fix

  • In absence of this APAR fix, the only way customer can
    recover
    system is to reboot it.
    

Problem summary

  • fcstat application running during link bounce events may hang.
