IBM Partner Pavilion DS4100 manual Hot-swap drive bays, Front controls and indicators

Attention: The DS4100 single-controller storage server does not support hot-swap RAID controllers or power supplies. You will lose access to data if you attempt to remove or replace a functioning (non-failed) RAID controller or power supply in a DS4100 single-controller storage server without first powering down the storage server.

Hot-swap drive bays

The hot-swap drive bays that are accessible from the front of your storage server are shown in Figure 2.

The DS4100 supports up to 14 DS4000 1.5 Gbps SATA hard disk drives. These drives are preinstalled in drive trays. The unit consisting of the drive and the drive carrier assembly is called a drive CRU. The SATA drive CRU includes the drive tray, the SATA drive, and the hard disk drive (HDD) interposer card. You install the drive CRUs in the 14 drive bays on the front of the storage server. There are no serviceable parts in a drive CRU. If it fails, it must be replaced in its entirety (drive, interposer, bezel, and tray).

Attention:

1.Never hot-swap a drive CRU when its associated green Activity LED is flashing. Hot-swap a drive CRU only when its associated amber Fault LED lights and is not flashing or when the drive is inactive and its associated green Activity LED lights and is not flashing.

2.The SATA drive and its HDD card are digitally signed together at the factory. Do not swap drives and interposers between drive CRUs. Do not replace one SATA drive with another SATA drive. These actions will result in a drive CRU that cannot be recognized by the storage server RAID controller.

3.After you remove a drive CRU, wait at least 70 seconds before replacing or reseating the drive CRU to allow the drive to properly spin down. Failure to do so may cause undesired events.

Note: If the hard disk drive you want to remove is not in a failed or bypass state, always use the DS4000 Storage Manager client program either to place the drive in a failed state or to place the array that is associated with the drive (or drives) in an offline state before you remove the drive from the enclosure.
