Select three-ASM disk for the high-redundancy diskgroup
Oracle 12c R1 introduced the Grid Infrastructure Management repository (also called Cluster Health Monitor
(CHM) repository), which is a central database used to store all the metrics database collected by the System Monitor
Service process of the Clusterware in all the cluster nodes. Currently, this repository is configured during Oracle
Grid Infrastructure installation. Refer to the CHM section in Chapter 2. Figure 2-6 shows the Grid Infrastructure
Management Repository Option that you can select during Grid Infrastructure installation. If you select the Grid
Infrastructure Management Repository option, the diskgroup you are going to create needs to be big enough to store
the CHM repository as well as OCR and voting disks; otherwise you will get the error message shown in Figure
5-11
.
In my test run, I allocated a 20GB diskgroup to store CHM repository, OCR, and voting disks. Once I made this ASM
diskgroup a bigger size such as 100 GB, this issue was solved.

The diskgroup has insufficient space for the CHM repository
