APAR status

  • Closed as program error.

Error description

  • Currently, all traces generated aixdiskpcm component go into
    a single trace buffer. This causes some not-so-interesting
    traces (such as getting device's pprc info) to flood the trace
    buffer and causing important pprc traces (such as failover
    etc) to get overwritten.

Problem summary

  • Currently, all traces generated aixdiskpcm component go into
    a single trace buffer. This causes some not-so-interesting
    traces (such as getting device's pprc info) to flood the trace
    buffer and causing important pprc traces (such as failover
    etc) to get overwritten.
    

Problem conclusion

  • Add a new child component named "pcm_pprc" to the
    'aixdiskpcmke' component, with a dedicated buffer that will be
    used for critical PPRC related operations (ops that change
    the state of the disk/group on AIX and/or the underlying
    storage device).
