Creating and Exporting LVM Volume Groups
Use the following procedure to create volume groups and export them for
access by other nodes. The sample script mk1VGs in the Samples
directory can be modified to automate these steps.
1. Define the appropriate Volume Groups on each node that might run
the application package. Use the commands:
# mkdir /dev/vgxx
# mknod /dev/vgxx/group c 64 0xnn0000
where the name /dev/vgxx and the number nn are unique within
the cluster.
2. Create volume groups only on the primary system. Use the vgcreate
and the vgextend command, specifying the appropriate HP-UX
device file names.
3. Use the vgexport command with the -p option to export the VGs on
the primary system without removing the HP-UX device files:
# vgchange -a n vgname
# vgexport -v -s -p -m mapfilename vgname
