# ioscan -m dsf /dev/disk/disk19
Persistent DSF Legacy DSF(s)
========================================
/dev/disk/disk19 /dev/dsk/c4t1d0
/dev/dsk/c5t1d0
• To view the persistent DSF corresponding to a legacy DSF (Note: A legacy DSF always
maps to a single persistent DSF)
o ioscan -m dsf <legacy_dsf>
# ioscan -m dsf /dev/dsk/c4t1d0
Persistent DSF Legacy DSF(s)
========================================
/dev/disk/disk19 /dev/dsk/c4t1d0
• To view mappings of all existing mass storage DSFs:
o ioscan -m dsf
# ioscan -m dsf
Persistent DSF Legacy DSF(s)

Mapping between legacy hardware paths and agile addressing
hardware paths
• To view lunpaths and legacy paths of a LUN. In the example below the LUN has two
lunpaths:
o ioscan -m hwpath -H <lun_hardware_path>
# ioscan -m hwpath -H 64000/0xfa00/0x3
Lun H/W Path Lunpath H/W Path Legacy H/W Path
====================================================================
64000/0xfa00/0x3
0/3/1/0.0x21000020371972ee.0x0 0/3/1/0.8.0.255.0.0.0
0/4/1/0.0x21000020371972ee.0x0 0/4/1/0.8.0.255.0.0.0
• To view the hardware path of the LUN, and the legacy hardware path corresponding to a
lunpath.
