Mapping between LUNs and LUN paths
To get information about the lunpaths of a LUN, run the following command:
o ioscan -m lun <persistent_dsf>
The example below shows the hardware path of disk20
( 64000/0xfa00/0x5), the hardware paths
of its 2 lunpaths (0/3/1/0.0x21000020371972eb.0x0, 0/4/1/0.0x21000020371972eb.0x0),
and its block and raw device files (/dev/disk/disk20, /dev/rdisk/disk20).
