Using Serviceguard Extension for RAC, 6th Edition, April 2008

procedure is described in the Managing Serviceguard Fifteenth Edition user’s
guide Appendix G.
• Initializing Disks for CVM
You need to initialize the physical disks that will be employed in CVM disk
groups. If a physical disk has been previously used with LVM, you should
use the pvremove command to delete the LVM header data from all the disks
in the volume group (this is not necessary if you have not previously used
the disk with LVM).
To initialize a disk for CVM, log on to the master node, then use the
vxdiskadm program to initialize multiple disks, or use the vxdisksetup
command to initialize one disk at a time, as in the following example:
# /etc/vx/bin/vxdisksetup -i c4t4d0
• Create the Disk Group for RAC
Use the vxdg command to create disk groups. Use the -s option to specify
shared mode, as in the following example:
# vxdg -s init ops_dg c4t4d0

# vxassist -g ops_dg make vol1 10240m
#vxassist -g ops_dg make vol2 10240m
# vxassist -g ops_dg make volsrvm 300m
