APAR status

• Closed as program error.

Error description

• AIX 6 and 7 introduced a pseudo file system for performance
  called AHA.
  Currently, when SRAs are deployed onto AIX hosts with that FS
  enabled, TPC issues a warning
  for that host. However, that FS should be ignored and handled
  like other pseudo file systems
  ( e.g. /proc file system on Linux ).
  

Local fix

• Upgrade to the latest version containing the fix.
