Internal drive bays - (NF 8500R - Type 8681)

Internal drive bays

Internal drives are installed in bays .
The server comes with one 3.5-inch, 1.44 MB diskette drive, one CD-ROM drive, and two hard disk drive bays.

•  The server comes with a preinstalled 3.5-inch, 1.44 MB diskette drive and a preinstalled integrated  drive electronics (IDE) CD-ROM drive.
•  The server supports one diskette drive only.
•  The server supports one slim-high (1-inch), 3.5-inch, hot-swap hard disk drive with a filler bezel or one  half-high (1.6-inch), 3.5-inch, hot-swap hard disk drive in each hot-swap bay.
•  The hot-swap bays connect to a SCSI backplane .
   This backplane is the printed circuit board behind the bay. The backplane supports up to two hard disk drives.
•  Empty hot-swap bays and trays that contain slim-high drives must contain a filler bezel.
•  The diskette drive uses 2 MB diskettes. For optimum use, format 2 MB diskettes to 1.44 MB.

Hard disk drives

The server comes with a Wide Ultra-2 SCSI (LVD) controller on the I/O function card.

Notes:

1.  LVD = low-voltage differential
2.  If you plan to install both internal and external SCSI devices, you must follow the instructions in 'External options', in addition to the instructions in this section.

A 16-bit (wide) SCSI cable connects the hot-swap backplane to one channel of the integrated SCSI controller on the I/O function card.

SCSI IDs: Each SCSI device that is connected to an individual integrated SCSI controller needs a unique identification (ID) so that the controller can identify the devices and ensure that different devices do not attempt to transfer data at the same time.
(The integrated SCSI controllers operate independently.)
If you need to set IDs for SCSI devices, refer to the instructions that come with those devices.

The server automatically sets SCSI IDs for hot-swap hard disk drives.
The server uses the hard disk drive SCSI IDs to send status information to the indicator lights located on each hot-swap drive.

Note: Do not set the SCSI ID jumpers on hard disk drives.

The SCSI backplane in the server supports up to two hot-swap drives.
Table 12 shows the default SCSI IDs that the backplane assigns for hot-swap hard disk drives.

Table 12. Automatically assigned SCSI IDs 

Bay	1	2
ID	0	1

Note: The default SCSI ID for the SCSI backplane is 15.
The default SCSI ID for each SCSI controller is 7.

A simplified layout of the SCSI backplane is shown in 'SCSI backplane component locations'.

The processing sequence for SCSI devices is set through the SCSISelect Utility program.
The default sequence proceeds from the lowest SCSI ID to the highest (0 to 6, then 8 to 14).
The default SCSI ID for each SCSI controller is 7.
The default SCSI ID for the SCSI backplane is 15.

Termination: All the internal hot-swap drives in the server have automatic termination.

Preinstallation steps: Before you install drives in the server, verify that you have all the cables and any other equipment specified in the documentation that comes with the internal drive.
You might also need to perform certain preinstallation activities.
Some of the steps are required only during the initial installation of an option.

1.  Choose the bay in which you want to install the drive.
2.  Verify that all jumpers are removed from the drive.
3.  To install the drive, continue with (below following) 'Installing or replacing a drive.'

Installing or replacing a drive

Notes:

1.  You do not have to turn off the server to install hot-swap drives in these bays.
2.  If these bays are not connected to a ServeRAID adapter, shut down and restart the server.
3.  If these bays are connected to a ServeRAID adapter, you can use the RAID management software to bring the  drives online.

    Refer to the ServeRAID adapter option documentation for instructions on installing a ServeRAID adapter.

4.  You do not have to turn off the server to remove a drive from a hot-swap bay, when that bay is  connected to a ServeRAID adapter.

If the amber hard disk status light for a drive is lit continuously, that individual drive is defective and needs to be replaced.
For additional information, see 'Internal drives installation'.
For the location of the hard disk status light, see 'Controls and indicators'.

  -Attention-

1.  Before you hot-swap a drive, refer to the amber hard-disk status light for that drive to make sure  that it is defective.
    If the server has a ServeRAID adapter installed and you assigned RAID level 1 or 5 to the logical drives in the disk  array, make sure that the drive is defective.
    If you partially or completely remove a good drive instead of a defective one, the server might lose valuable data.
    However, the ServeRAID adapter can rebuild the data that you need, provided that certain conditions are met.
    Refer to the ServeRAID adapter documentation for further details.
2.  To avoid damage to a hard disk drive, do not remove the drive from the hot-swap bay until it  has had time to spin down (approximately 30 seconds after disconnecting).
    Handle the drive gently.

Before you begin:

•  Read 'Safety information'.
•  Read the documentation that comes with the drive.

1.  Determine the bay in which you want to install the drive. Otherwise, continue with (below) step 2.

    Remove the defective hard disk drive -2- by pressing on the lock to release the handle -3-, placing the  handle in the open position (perpendicular to the drive), and pulling the hot-swap tray from the bay.
    Continue with (below) step 3.

2.  Remove the filler panel -1- from the empty hot-swap bay by inserting your finger into the depression at the  left side of the filler panel and pulling it away from the server.

   Note: If you are installing a slim-high drive, you must separate the slim filler bezel from the tray, and  insert the slim filler bezel into the top of the hard disk drive cage.  Otherwise, store the filler panel in a safe place.

3.  Install the hard disk drive -2- in the hot-swap bay:
   1.  Remove the new drive assembly from the static-protective package.
   2.  Touch the static-protective package containing the drive assembly to any unpainted metal surface on the server.
       Then, remove the drive assembly from the static-protective package.
   3.  If you are installing a slim-high drive, separate the slim filler bezel from the tray, and insert the  slim filler bezel into the top of the hard disk drive cage.
   4.  Ensure that the tray handle -3- is open (that is, perpendicular to the drive).
   5.  Align the drive assembly so that it engages the guide rails in the bay.
   6.  Gently push the drive assembly into the bay until the drive stops.
   7.  Push the tray handle to the closed (locked) position.

4.  Check the hard disk drive status indicators to verify that the hard disk drives are operating properly.

   Note: If the server has a ServeRAID adapter installed, refer to the ServeRAID adapter documentation  for details about configuration requirements.
    Record the configuration information.
