Replacing a hot-plug hard disk
1. Identify the disk that has failed as described in How do I know a disk has failed? (page 137).
NOTE: Remember you can use the Beacon LED to identify the physical disk in the unit.
2. HP D2D4100 Series: The hard drives installed in the server are labeled from device 1 to device
12, from left to right, top to bottom, when viewed from the front of the server.
HP D2D4300 Series: The hard drives in the internal shelf are installed in two columns in the
server and each column is physically labeled from device 1 to device 6, bottom to top. When
viewed from the front of the server, the disks 1 to 6 in the far-right column relate to disks 1 to
6 on the Web Management Interface. The disks 1 to 6 in the inner column relate to disks 7
to 12 on the Web Management Interface. In the expansion shelves, they are installed in four
columns and are labeled from top to bottom, left to right.
