Account Environment: AIX7.1 + Dual-node Oracle RAC 11.2.0.3
Since this set of RAC is not installed in its own department, it is installed by the development department and is now managed by the Operations section, and customers need to command the ASM DiskGroup Name Installation Department specification. The oasmdgdata1 needs to be changed to DATADG. Fortunately, Oracle's version is 11GR2, and in 11gr2, Oracle has a new feature that allows you to change the DiskGroup name directly using the RENAMEDG command. Here are the specific steps.
