Pinned topic nmon in recording mode keeps /dev/hdisk devices busy

‏2014-06-05T19:49:14Z |

After upgrading AIX to 6100-09-01-1341 (bos.perf.tools 6.1.9.1) and running nmon in recording mode (nmon -x -m /var/nmon), we find that nmon holds all the /dev/hdisk devices (that nmon sees at start) busy so that we can't run rmdev.  We have to kill the nmon process to remove an hdisk device.  I don't recall that previous versions of nmon had this issue.  Is there a way to run nmon in recording mode and avoid this issue?

    See APAR IV54958 - upgrade to SP3 is supposed to solve this problem.
