Veritas Volume Manager 5.0 Release Notes HP-UX 11i v3 (5992-1952, August 2011)

Prior to running this procedure, ensure that there are no applications accessing VxVM volumes
and no file system is mounted on VxVM volumes. To migrate from HP-UX native multipathing to
DMP, complete the following steps:
1. To stop all volumes in each disk group on the system, enter the following command:
# vxvol –g diskgroup stopall
2. To initiate the migration, enter the following commands:
# vxddladm rmforeign blockdir=/dev/disk chardir=/dev/rdisk
# vxconfigd –kr reset
3. To restart all the volumes in each disk group, enter the following command:
# vxvol –g diskgroup startall
The output from the vxdisk list command shows the DMP metanode names according to the
current naming scheme.
Output in the default old naming scheme:
# vxdisk list
