Performing Bad Block Recovery with Oracle Enterprise Manager

The procedures that you use in Oracle Enterprise Manager to perform bad block recovery correspond to the steps that you could manually perform with the remap command using the Oracle ASM Command utility (ASMCMD). Use the following procedures to perform bad block recovery:

Access the Oracle Automatic Storage Management home page.

See "Accessing the Oracle Automatic Storage Management Home Page" for instructions.
Click the Disk Groups link at the top of the page.
If you are not logged in, then the Log In page appears and you should log in as the SYS user, connecting as SYSASM. Provide the SYS password for the Oracle ASM instance. This password was set up when the Oracle ASM instance was created.
Click a disk group name and Oracle Enterprise Manager displays the disk group home page for that disk group.
Click a box in the Select column to the left of a disk in which to recover bad blocks, then click Recover Bad Blocks.

Note:

You can only recover bad blocks for disk groups that you have configured with normal or high redundancy; you cannot use this feature for disk groups that you have configured with external redundancy.
