Using Serviceguard Extension for RAC, 5th Edition, June 2007

Serviceguard Configuration for Oracle 10g RAC
Displaying the Logical Volume Infrastructure
Chapter 2 85
# mkdir /dev/vg_ops
# mknod /dev/vg_ops/group c 64 0xhh0000
For the group file, the major number is always 64, and the
hexadecimal minor number has the form
0xhh0000
where hh must be unique to the volume group you are creating. If
possible, use the same number as on ftsys9. Use the following
command to display a list of existing volume groups:
# ls -l /dev/*/group
4. Import the volume group data using the map file from node ftsys9.
On node ftsys10 (and other nodes, as necessary), enter:
# vgimport -s -m /tmp/vg_ops.map /dev/vg_ops
