get_wwn
The get_wwn utility lists all discovered devices and their worldwide names. The utility is found in the /opt/TRSANfcd/bin directory. For example, with two controllers on the same loop, seeing the same storage, a result similar to the following appears:
apollo# get_wwn loop0
target 1 lun 0 wwn 0x2000002037119126 target 2 lun 0 wwn 0x200000203711534c target 3 lun 0 wwn 0x2000002037114102 target 4 lun 0 wwn 0x20000020371140ff target 5 lun 0 wwn 0x20000020371119a8 target 6 lun 0 wwn 0x2000002037119ba1 target 7 lun 0 wwn 0x2000002037116035 target 8 lun 0 wwn 0x2000002037116008 loop1

Note The get_wwn utility provides information from memory rather than doing an active scan of the loop. During a system reboot, get_wwn is updated to reflect the current SAN world wide name topology.
