    In our scripts we first check disk paths by running the lspath -l hdisk#‌ " command, then in order to confirm if virtual fiber channel adapter is coming from both the VIO's we run "echo vfcs fcs0 | kdb | grep "host_name" to check the VIO server name. please let us know if there is any other command by which we can confirm in AIX 7.2 if virtual fcs adapter is coming from which VIO server.
