Refer to the following guidelines when you configure the SCSI drive:
l Disable termination on the drive. The SCSI backplane board provides termination for the SCSI bus.
l Set the SCSI ID on all drives to 0. All SCSI ID numbers for the drives are set by the SCSI backplane board.
l Configure the drive so that the drive motor waits for a Start Unit command from the SCSI host adapter before spinning.
You may need to use different programs than those provided with the operating system to partition and format SCSI hard-disk drives. See "Installing and Configuring
SCSI Drivers," in the User's Guide for information and instructions.
When you format a high-capacity SCSI hard-disk drive, allow enough time for the formatting to be completed. Long format times for these drives are normal. A 9 GB
hard-disk drive, for example, can take up to 2.5 hours to format.
Installing a SCSI Hard-Disk Drive
1. If the system does not have a RAID controller installed, shut down the system.
2. Open the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").
3. Open the hard-disk drive carrier handle (see Figure7-2).
Figure 7-2. Installing a SCSI Hard-Disk Drive Carrier
4. Insert the carrier into the drive bay (see Figure7-2).
5. Close the drive carrier handle to lock the drive in place.
6. Close the front bezel.
7. Install any required SCSI device drivers (see "Installing and Configuring SCSI Drivers," in the User's Guide for information).
8. If the hard-disk drive is a new drive, run the SCSI Controllers test in the Dell Diagnostics.
Removing a SCSI Hard-Disk Drive
1. If the system does not have a RAID controller installed, shut down the system.
2. For systems with Dell PERC host adapter cards, power down the hard-disk drive bay and wait until the SCSI hard-disk drive indicator codes on the drive
carrier signal that the drive may be removed safely.
If the drive has been online, the drive status indicators will flash sequentially as the drive is powered down. When all indicators are turned off, the drive is ready
