How to Create a ASM Disk Group

To isolate non-crucial backups from crucial data in the current disk group DATA, a separate new disk group with new disks is needed to put all backups. For meeting our new requirement, we plan to create a disk group called FRA, i.e. Fast Recovery Area, by ourselves. The utility that we are going to use is asmca which is a binary of user grid.

[grid@primary01 ~]$ asmca

Please note that, you have to call asmca by grid, not root.
