Utilities
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 8 lun 0 wwn 0x2000002037116008
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.
