IBM eServer OpenPower 710 Technical Overview and Introduction
The control panel and DVD drive share the same bay. The front bezel cover must be
removed to remove the DVD device and the control panel/media bay. This control
panel/media bay is controlled by the integrated IDE controller.
Table 2-5 Available and supported internal media devices
2.6.2 Internal hot-swappable SCSI disks
The OpenPower 710 server can have up to four hot-swappable disk drives. The hot-swap
process is controlled by the SCSI enclosure service (SES), which is provided by the
integrated SCSI Ultra320 controller. Table 2-6 lists available and supported hot-swappable
drives.
Table 2-6 Hot-swappable disk drive options
The system configuration shipped will have the first two SCSI disks installed in disk drive
SCSI IDs 8 and 5. The drives at ID 8 and ID 5 are hardwired to spin up immediately during
startup sequencing. The remaining drives will spin up under software control (typically 5
seconds intervals). The disk drive placement priority is SCSI ID 8, 5, 4, and then 3. See
Figure 1-2 on page 3 for each SCSI ID location.
Prior to the hot-swap of a disk in the hot-swappable capable bay, all necessary operating
system actions must be undertaken to ensure that the disk is capable of being deconfigured.
After the disk drive has been deconfigured, the SCSI enclosure device will power off the bay,
enabling safe removal of the disk. You should ensure that the appropriate planning has been
given to any operating-system-related disk layout.

1993 IBM 4.7 GB IDE Slimline DVD-RAM Drive
Note: The hot-swappable disk drive is only available with Linux 2.6 kernel. An OpenPower
710 server not running the Linux 2.6 kernel must be shut down and powered off before you
replace any disk drives.

Note: We recommend that you use the following procedure after the disk has been decon-
figred, when removing a hot-swappable disk:
1. Release the tray handle on the disk.
2. Pull out the disk assembly a little bit from the original position.
3. Wait up to 20 seconds until the internal disk stops spinning.
4. Now you can safely remove the disk from the DASD backplane.
