If an automatic Replace Member occurs using a source drive that was originally a hot spare (that was used in a rebuild), and a new drive added for the Replace Member operation as the target drive, the hot spare reverts to the hot spare state after a successful Replace Member operation. Manual Replace Member Operation In addition to the automatic Replace Member operation, you can perform a manual Replace Member operation. Perform the following steps to carry out a manual Replace Member operation: 1 Select a physical disk in the left panel of the main menu screen. 2 Click the Operations tab in the right panel. The utility identifies the drives you can use to replace existing drives in the virtual disk. 3 Click Go to carry out the Replace Member operation. After the controller copies data from the commissioned hot spare to the newly-inserted drive, the new drive is part of the virtual disk and the hot spare reverts back to being a ready hot spare. Restrictions and Limitations The following restrictions and limitations apply to the Replace Member operation: • The Replace Member functions are restricted to one per array for RAID 0, RAID 1, and RAID 5, and two per array for RAID 6. • The Replace Member function and rebuild cannot run simultaneously on a RAID 6 virtual disk. The rebuild operation has a higher priority, and the Replace Member operation will be aborted if a rebuild begins. Changing Adjustable Task Rates You can change adjustable task rates for the Dell PERC 5/i controller and the Dell PERC 6/i controller. Follow these steps if you need to change the adjustable rates for rebuilds, patrol reads, and other system tasks that run in the background: 36 Configuration
