Hard Disk Drives
Your system supports a variety of SCSI hard disk drives installed in the
system’s hard disk drive bay. Contact your sales representative or dealer for a
list of approved devices.
The 3.5-inch hard disk drive bay on the front of the server contains six slots on
which hard disks can be installed. A hard disk having the thickness of 1 inch can
be installed in each of the slots. The SCSI IDs of the slots are fixed to ID0 to
ID5 from bottom to top.
In the configuration at the shipment, the cable on the 3.5-inch hard disk drive
bay is connected to the Ultra320/160 SCSI (A) connector on the system board.
To provide the disk array configuration, connect the cable on the 3.5-inch hard
disk drive bay to the disk array controller. The SCSI standard of the hard disk
to be added should be the same as that of the existing disks.
A dummy tray is installed in an empty slot of the 3.5-inch hard disk drive bay.
This is intended to improve the cooling effect within the server. Always install
a dummy tray in any slot in which a hard disk is not installed.
IMPORTANT:
A specified dummy tray must be used.
Installation
If installing new drives, follow an installation scheme starting with the bottom-
most drive. Fill the bays bottom-to-top.
NOTE:
Hard disks can be installed or removed from the server only by
opening the front bezel. In the disk array configuration, hard disks may be
installed or removed with the power of the server on.
IMPORTANT:
In the disk array configuration, hard disks configuring a
specific pack should have the same specification including the capacity.
1.
See the section Preparing Your System for Disassembly and Reassembly
described earlier to prepare (in other than the disk array configuration).
2.
Release the lock of the front bezel by using the security key to open the front
bezel.
3.
Check the slot in which the hard disk is installed.
4. Remove the dummy tray. See Figure 4-19.
