Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

To migrate from DMP to HP-UX native multi-pathing
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
multi-pathing 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 multi-pathing 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 multi-pathing metanodes, and cannot display legacy names for the
devices.
