3.4.2 Creating Shared LVs and File Systems
Use the smit crjfs fast path to create the shared file system on the source node. When you create a journaled file system, AIX creates the corresponding logical volume. Therefore, you do not need to define a logical volume. You do, however, need to later rename both the logical volume and the log logical volume for the file system and volume group.

Renaming a jfslog and Logical Volumes on the Source Node
AIX assigns a logical volume name to each logical volume it creates. Examples of logical volume names are /dev/lv00 and /dev/lv01. Within an HACMP cluster, the name of any shared logical volume must be unique. Also,
