Planning and Documenting an HA Cluster
CVM and VxVM Planning
Chapter 4154
• The cluster lock disk can only be configured with an LVM volume
group.
• VxVM disk group names should not be entered into the cluster
configuration ASCII file. These names are not inserted into the
cluster configuration ASCII file by cmquerycl.
CVM and VxVM Worksheet
The following worksheet will help you organize and record your specific
physical disk configuration. This worksheet is an example; blank
worksheets are in Appendix F. Make as many copies as you need. Fill out
the worksheet and keep it for future reference.
This worksheet includes volume groups and physical volumes. If you are
using the cluster file system, begin planning your multi-node packages
here.
The Package Configuration worksheet (presented later in this chapter)
contains more space for recording information about the logical volumes
and file systems that are part of each volume group.
