it's in symaudit (run it with -v). Here is HBA 1000000000000123 being added to an initiator group ig_sunserver   
Is there a log file/way to look at the symaccess command history?  I want to find out details about  hba's being added/deleted to/from a initiator group, logs of luns being added to a storage group. I tried symapi log files and symaudit but they were not useful for getting the info I needed.  Any input is greatly appreciated. Thanks in advance.
