The hwmgmtd utility might not provide accurate results when run on a SPARC T3 system. Some other Oracle Hardware Management Pack utilities (such as raidconfig, hwmgmtcli, storageviewer) can also run very slowly on a SPARC T3 system.
These problems are due to a Solaris issue documented in CR 6937169.
