2.6 Administer the Storage Devices in an Exascale Storage Pool

Use the following procedures to administer the storage devices in an Exascale storage pool. If your system is configured to use Exascale and Oracle ASM (also known as a hybrid storage configuration), use these procedures in conjunction with the directions at Maintaining Oracle Exadata Storage Servers (in the Oracle Exadata Database Machine Maintenance Guide).

• Replacing a Failed Storage Device
  Failure of a storage device can affect performance and data redundancy. Consequently, a failed storage device should be replaced as soon as possible.
• Proactively Replacing a Storage Device
  You may need to proactively replace a storage device that has not failed.
