Replacing An Existing Disk With a New Disk

To replace an existing disk with a new disk, follow these steps:

  1. Access the Oracle Automatic Storage Management home page.

    See "Accessing the Oracle Automatic Storage Management Home Page" for instructions.

  2. Click the Disk Group tab. The Disk Group page displays.

  3. Select a Disk Group. The Disk Group page appears which shows all Member Disks that belong to the disk group.

  4. Select an offline disk to replace. The Replace Disks page is displayed.

    Select a new disk of size equal to or greater than the original disk being replaced to ensure the same level of data protection.

  5. Select a new disk and then specify the options, such as Rebalance Power, and then click OK. The disk is then replaced. Rebalance operations redistribute data evenly across all drives. Oracle ASM automatically rebalances a disk group whenever disks are added or dropped. To manually rebalance all disk groups, you must specify the Rebalance Power. Higher values use more I/O bandwidth and complete rebalance more quickly. Lower values cause rebalance to take longer, but use less I/O bandwidth. Values range from 0 to 1024.
