All data from the array is lost, regardless of the RAID levels assigned to the logical drives. To replace a faulty drive: 1. Before you remove or replace a drive that you suspect to be defective, verify that the drive is defective. To do this: a. Check the drive for damage. b. Verify that the drive is positioned correctly. If the drive is not installed correctly, reposition the drive. c. Check the lights on the drive tray. (See the following information for a description of the lights.) Verify that you can remove the drive safely. The lights on the hot-swap drive tray provide drive status information, as follows: Hard Disk Activity Light: When this green light is flashing, it indicates that the server is accessing the drive. Hard Disk Status Light: When this amber light is lit continuously, it indicates that the drive has failed. When the light flashes slowly (one flash per second), it indicates that the hard disk drive is part of a disk array and is being rebuilt. When the light flashes rapidly (three flashes per second), it indicates that the controller is identifying the drive. The drive should not be replaced if this light is blinking; the drive has just been replaced and the disk array is being rebuilt. 2. Physically replace the defective drive or use an existing RDY drive that has a capacity equal to or greater than the drive that you are replacing as a hot-spare replacement drive. Attention Removing the wrong hard disk drive might cause loss of all data in the array. . a. To physically replace the defective hard disk drive, follow the instructions in "Internal drive installation" on page 197 and "Installing a drive in a hot-swap bay" on page 203; then, follow the instructions in "Understanding the drive rebuild process" on page 131. b. To rebuild the defunct drive to an existing RDY drive, follow the instructions in "Understanding the drive rebuild process" on page 131. 130 Netfinity Server HMM
