Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

If the migration involves a currently booted disk, you must reboot the system.
Specifying the –r option with the vxddladm addforeign command and the
vxddladm rmforeign command, automatically reboots the system.
See the Storage Foundation Release Notes for limitations regarding rootability
support for native multipathing.
To migrate from DMP to HP-UX native multipathing
1
Stop all the volumes in each disk group on the system:
# vxvol -g diskgroup stopall
2
Use the following commands to initiate the migration:
# vxddladm addforeign blockdir=/dev/disk chardir=/dev/rdisk
# vxconfigd -kr reset
For migration involving a current boot disk, use:
# vxddladm -r addforeign blockdir=/dev/disk chardir=/dev/rdisk
3
Restart all the volumes in each disk group:
# vxvol -g diskgroup startall
The output from the vxdisk list command now shows only HP-UX native
multipathing metanode names, for example:
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
disk155 auto:LVM - - LVM
disk156 auto:LVM - - LVM
disk224 auto:cdsdisk - - online
disk225 auto:cdsdisk - - online
disk226 auto:cdsdisk - - online
disk227 auto:cdsdisk - - online
disk228 auto:cdsdisk - - online
disk229 auto:cdsdisk - - online
When HP-UX native multipathing is configured, no DMP metanodes are
configured for the devices in the /dev/disk and /dev/rdisk directories. As
a result, the vxdisk list command only displays the names of the HP-UX
native multipathing metanodes, and cannot display legacy names for the
devices.
