Use the following command to determine the version of a disk group:

# vxdg list <diskgroup>

To upgrade a disk group to version 160, use the following command:

# vxdg upgrade <diskgroup>

After you upgrade from a previous release of VxVM, HP recommends that you upgrade to the latest disk group version.

For more information on disk groups, see the Veritas Volume Manager 5.1 SP1 Administrator's Guide. To locate this document, go to the HP-UX Core docs page at: www.hp.com/go/ hpux-core-docs. On this page, select HP-UX 11i v3.

Native Multipathing with Veritas Volume Manager

By default, VxVM uses DMP to manage multiple paths to I/O devices. It is possible to configure VxVM to use HP-UX native multipathing instead by defining I/O devices as foreign devices, which are bypassed by DMP. To revert to using DMP, you must remove the I/O devices from the foreign device list. This section outlines a system-wide procedure to switch between using DMP and using HP-UX native multipathing using the vxddladm addforeign and vxddladm rmforeign commands. Using the procedure you can migrate all devices in the /dev/disk and /dev/rdisk directories. To migrate an individual device or only a subset of devices, see vxdiskadm3(1M).

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

CAUTION: Before switching between DMP and HP-UX native multipathing, ensure that no application is accessing the VxVM volumes and no file system is mounted on the VxVM volumes. Otherwise, you cannot complete the following procedure. The following procedure cannot be used on a system that has VxVM root disks.

Prior to migrating from DMP to HP-UX native multipathing, ensure that there are no applications accessing VxVM volumes and no file system is mounted on VxVM volumes.

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

1.Stop all volumes in each disk group on the system:

#vxvol –g diskgroup stopall

2.Initiate the migration:

#vxddladm addforeign blockdir=/dev/disk chardir=/dev/rdisk

#vxconfigd –kr reset

3.Restart the volumes in each group:

#vxvol –g diskgroup startall

The output from the vxdisk list command now displays a list of devices following the agile naming scheme of the operating system instead of the DMP metanode names

For example:

# vxdisk list
