leqacy view & Legacy DSF + HP-UX 11i v3

[Grayh]

HP-UX 11i v3 introduces a new representation of mass storage devices called the agile view. In this representation, the device special file (DSF) name for each disk no longer contains path (or link) information. The multi-pathed disk has a single persistent DSF regardless of the number of physical paths to it. The legacy view, represented by the legacy DSF, continues to exist.

If I understand your question right, this may answer your question:

The command will list "old" and "new" device files for the storage devices, example:

# ioscan -m dsf
Persistent DSF Legacy DSF(s)
========================================
/dev/rdisk/disk10 /dev/rdsk/c1t0d0
/dev/rdsk/c2t0d0
/dev/rdisk/disk11 /dev/rdsk/c1t0d1
/dev/rdsk/c2t0d1

This is simply the device files and view you are used to, as used prior to HP-UX 11iv2.
for example /dev/rdsk/c0t0d0 or /dev/dsk/c2t6d0
