Pinned topic topas_nmon locking vg and preventing powerha failover?

‏2014-02-01T12:55:27Z |

We are running nmon (from AIX 7.1 TL3 SP1) and PowerHA 6.1 EE (6.1.0 SP9).  Has anyone noticed that topas_nmon locks the volume groups and prevents a failover?

    I am assuming that you are talking about nmon in batch mode writing to a filesystem in the volume group ? can you clarify / explain your setup a little more ? 

    HA should kill and unmount any filesystems, however, if the i/o is stuck in kernel mode then killing the proc may not be within the required timeframe .. have you got any I/O issues with the underlying disks ?
