I always forget where the patching logs are kept.
/var/sadm/install_data/ /var/sadm/install_data/s10s_rec_patchset_short_2013.10.26_02.32.30.log /var/sadm/install_data/s10s_rec_patchset_verbose_2013.10.26_02.32.30.log /var/sadm/install_data/s10s_rec_patchset_failed_2013.10.26_02.32.30.log /var/sadm/install_data/_patchadd_2013.10.26_02.32.30.log /var/sadm/install_data/_patchadd_subproc_2013.10.26_02.32.30.log
The individual patch log files can also be inspected under
/var/sadm/patch/PatchID/log
