Using Oracle Enterprise Manager, you can monitor the total capacity of your disk groups, including the amount of unused space and the amount of unused space that can be safely utilized after taking mirroring into account.
To view Automatic Storage Management (ASM) disk group usage and free space:
Go to the ASM Home page.
Click the Disk Groups link to view the Disk Groups subpage.
If the Automatic Storage Management Login page appears, log in as the SYS user, connecting as SYSASM. Provide the SYS password that was set when the ASM instance was created.
The Disk Groups subpage displays all disk groups with their space usage information.
Note:
The Usable Free column displays the space in gigabytes (GB) that is actually available in the disk group. It takes into account the redundancy level of the disk group, and excludes the space that the disk group reserves for restoring full redundancy for all files in the disk group after a disk failure.
