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

Serviceguard Configuration for Oracle 9i RAC
Creating a Storage Infrastructure with CVM
Chapter 3174
Initializing Disks for CVM 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:
# /usr/lib/vxvm/bin/vxdisksetup -i /dev/dsk/c0t3d2
Creating Disk Groups 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 c0t3d2
Verify the configuration with the following command:
# vxdg list
NAME STATE ID
rootdg enabled 971995699.1025.node1
ops_dg enabled,shared 972078742.1084.node2
