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.
Local fix
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).
Temporary fix
