2-8 Removal and Replacement Procedures n Never remove a drive while another drive is being rebuilt. A drives' On-line LED will be flashing green whenever it is being rebuilt. A replaced drive is restored from data stored on the other drives. n Never turn a ProLiant Storage System off while the Server controlling it is powered on. Doing so will cause the server's SMART Controller to mark the drives as "failed." This could result in permanent data loss. n If an on-line spare drive is installed, wait for it to complete rebuilding before replacing the failed drive. When a drive fails, the on-line spare will become active and begin being rebuilt as a replacement drive. After the on-line spare has been completely rebuilt (On-line LED will be on solid), the failed drive should be replaced with a new replacement drive. Do not replace the failed drive with the on-line spare. n A POST error message (1786) will occur when the system is turned on if a drive(s) has been replaced while the system is OFF. When this occurs you will be prompted to: PRESS F1 TO BOOT THE SYSTEM AND REBUILD THE REPLACED DRIVE OR, PRESS F2 TO BOOT THE SYSTEM AND NOT REBUILD THE DRIVE(S). CAUTION: Pressing F2 will cause permanent data loss to the entire logical drive. F2 should be pressed only if all of the drives have been replaced or if complete data loss is desired. Replacing Hot-Pluggable Hard Drives The front access drive bay area is located behind the front bezel door and can hold up to four half height hot-pluggable hard drives. Figure 2-9.
