Make sure to copy the map files to all of the nodes. The sample script Samples/ftpit shows a semi-automated way (using ftp) to copy the files. Only enter the password interactively.

8.De-activate the volume group.

# vgchange -a n /dev/vgname

NOTE: With the introduction of mass storage stack’s Native Multi-pathing functionality in HP-UX 11i v3, it is no longer required nor recommended to configure PV links.

Configuring Volume Groups using Native Multi-pathing

Starting with HP-UX 11i v3, Secure Path is no longer supported. Use the Native Multi-pathing available on HP-UX 11i v3.

Complete the following procedure to configure volume groups using Native Multi-pathing:

1.Create the volume groups on the source volume which uses Native Multi-pathing.

The following commands are an example of how volume groups using Native Multi-pathing are created for the vdisk identified by WWN

6005-08b4-0010-203d-0000-6000-0017-0000:

#pvcreate -f /dev/rdsk/disk41

#vgcreate /dev/vgname /dev/dsk/disk41

2.Create the logical volumes.

#mkfs vxfs /dev/<vg_name>/lvol1

3.Install a VxFS file system on the logical volumes:

#newfs -F vxfs /dev/vgname/rlvol1

4.De-activate the Volume Groups.

#vgchange -a n /dev/vgname

5.Start the cluster and configure the Volume Groups.

#cmruncl (if cluster is not already up and running)

#vgchange -c y /dev/vgname

6.Test the Volume Groups activation with exclusive option.

#vgchange -a e/dev/vgname

7.Create a back-up conffile that will contain the cluster ID, already having an ID on disks/ luns.

#vgcfgbackup /dev/vgname

8.Use the vgexport command with the-poption to export the Volume Groups on the primary system without removing the HP-UX device files.

#vgexport -s -p -m mapfile /dev/vgname

Make sure to copy the map files to all of the nodes. The sample script Samples/ftpit shows a semi-automated way (using ftp) to copy the files. Only enter the password interactively.

9.De-activate the volume group.

# vgchange -a n /dev/vgname

NOTE: While creating a volume group, you can choose either the legacy or agile Device Special File (DSF) naming convention. To determine the mapping between these DSFs, use the # ioscan –m dsf command.
