This procedure essentially instructs DMP to bypass all auto-configured devices. As a result, no DMP metanodes are created under /dev/vx/[r]dmp directory. VxVM names these devices according to their corresponding agile or persistent device special files (DSFs) assigned by the operating system.

CAUTION: Foreign devices are not supported as cluster-sharable disks. Do not perform this procedure on systems that require clustering features of VxVM (CVM).

NOTE: Irrespective of the mode set, if you use the vxddladm or the vxdisk list commands, only the new style DSFs are displayed after migrating to HP-UX native multipathing. Enclosure-based naming scheme is not supported for foreign devices.

NOTE: Administrative commands, such as vxdmpadm iostat or vxdmpadm setattr, which operate on the level of enclosures, controllers or dmpnodes, are not supported and will not work with foreign devices

Migrating from DMP to HP-UX native multipathing for systems that have VxVM root disks

Foreign devices are not supported as cluster-sharable disks. You cannot use this procedure on systems requiring clustering features of VxVM (CVM).

To migrate from DMP to HP-UX native multipathing, complete the following procedure:

1.To migrate to agile addressing mode, enter the following command:

#vxddladm set namingscheme=osn mode=new

2.To initiate the migration, enter the following command:

#vxddladm addforeign blockpath=/dev/disk/<root disk> charpath=/dev/rdisk/<rootdisk>

Following are the message that are displayed:

VxVM vxddladm INFO V-5-1-0 Transactions are disabled until the reboot.

VxVM vxddladm INFO V-5-1-0 Root device has been added to foreign device category changes will be effective only after reboot

VxVM vxddladm INFO V-5-1-0 Please reboot the system

3.Restart the system.

4.Complete the procedure listed in the Migrating from DMP to HP-UX native multipathing for systems that do not have VxVM root disks section.

NOTE: Administrative commands which operate on the level of enclosures, controllers or dmpnodes, such as, vxdmpadm iostat, vxdmpadm setattr, are not supported and will not work correctly on foreign devices.

Migrating from HP-UX native multipathing to DMP for systems that do not have VxVM root disks

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
