Installing A Hot-Swap Hard Disk Drive In Bay 5, 6, Or 7 - IBM 8646 - Eserver xSeries 220 Hardware Maintenance Manual

Installing a hot-swap hard disk drive in bay 5, 6, or 7

If the server is a hot-swap model, it contains hardware that you can use to replace
a failed hard disk drive without turning off the server. Therefore, you have the
advantage of continuing to operate the system while a hard disk drive is removed
or installed. These drives are known as hot-swap drives. If these drives are
connected to an optional controller, such as a ServeRAID controller, that supports
this function, and if one of these drives becomes defective, the ServeRAID
controller can rebuild the data from that drive onto another hot-swap drive. Refer
to the information that comes with the ServeRAID controller for details.
Each hot-swap drive has two indicator lights: the hard disk drive activity light and
the hard disk drive status light. When the green hard disk drive activity light is
flashing, the controller is accessing the hard disk drive. When this occurs, the SCSI
activity light on the front of the server also illuminates. The SCSI activity light is
illustrated and described in "Server controls and indicators" on page 7. If the
amber hard disk drive status light for a drive is lit continuously, that individual
drive is faulty and requires replacement. When the hard disk drive status light
indicates a drive fault, you can replace a hot-swap drive without turning off the
server.
Note: The hard disk drive activity light is also known as the SCSI hard disk drive
Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive
tray. The drive must have a single connector attachment (SCA) connector.
Hot-swap-drive trays come with hot-swap drives.
The hot-swap bays connect to a SCSI backplane. This backplane is the printed circuit
board behind the bay. The backplane controls the SCSI IDs for the hot-swap drives.
The following illustration shows the hot-swap-drive backplane component
locations, as viewed from the front of the server.
