What storage? What FC adapter?

I have tried enabling dynamic tracking and delayed_fail on the FC adapter and have played with numerous timeout setting but to no avail. AIX does not recognise when a failed path is available again unless I either reboot the host or initiate cfgmgr from the command line to force the FC adapter to rescan.
What needs to be changed to allow AIX to automatically recognise when a dead path is back online?
I am not sure what you mean by "
I have tried enabling [...] delayed_fail on the FC adapter". I'd try enable fast_fail of the fscsi device. Put all children of all fscsi devices in the defined state
# rmdev -l fscsiX -R
change the policy from delayed_fail (i.e. off) to fast_fail (i.e. on) on every fscsi device
# chdev -l fscsiX -a fc_err_recov=fast_fail
Run cfgmgr to reconfigure all devices back to the available state.
# cfgmgr
