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

Serviceguard Configuration for Oracle 9i RAC
Displaying the Logical Volume Infrastructure
Chapter 3 153
# 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 format:
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
