slave: ever3b

6. Converting Disks from LVM to CVM

Use the vxvmconvert utility to convert LVM volume groups into

CVM disk groups. Before you can do this, the volume group must be

deactivated, which means that any package that uses the volume

group must be halted. This procedure is described in the Managing

Serviceguard Twelfth Edition user’s guide Appendix G.

7. Initializing Disks for CVM/CFS

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

8. 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 cfsdg1 c4t4d0

9. Create the Disk Group Multi-Node package. Use the following

command to add the disk group to the cluster:

# cfsdgadm add cfsdg1 all=sw

The following output will be displayed:
