I tried migrating to legacy ddsf to persistent dsf by using following command,
rmsf -L (Which removes all the instances of the legacy dsf from the system)
Afetr running this command there were no dsfs found in the path /dev/dsk, as rmsf -L removed all the legacy devices.
After this when I ran ioscan -funC disk command, to scan the and list devices, I was not able to see any disk devices. Can some one tell me what went wrong here?

In HP-UX 11i v3 Persistent DSF Migration Guide, they say that after rmsf -L you won;t be able to list the disk deices. Then how admin can identify the disk devices?
Can some one guide me here?

Note that DRD guide notes that Legacy I/O must be enabled. This is certain for VxVM boot systems, and a probably for LVM(I have not checked.).
Also, there is an Ignite bug I learned about the hard way, with legacy I/O the system was unrecoverable. That was also a VxVM booted system. I don't know what the impact is on an LVM booted system.
Migrator be forwarned.
