SCSI Hard Drives
This subsection describes how to install and configure SCSI hard drives in the system's internal hard-drive bays.
Before You Begin
Before attempting to remove or install a drive while the system is running, see the documentation for the RAID controller card ensure that the system is
configured correctly to support hot-pluggable drive removal and insertion.
SCSI hard drives are supplied in special drive carriers that fit in the hard-drive bays.
You may need to use different programs than those provided with the operating system to partition and format SCSI hard drives. See "Installing and
Configuring SCSI Drivers" in the User's Guide for information and instructions.
When you format a high-capacity SCSI hard drive, allow enough time for the formatting to be completed. Long format times for these drives are normal. For
example, an exceptionally large drive can take over an hour to format.
SCSI Backplane Board Configuration
The hard-drive bays provide space for up to five 1-inch SCSI hard drives. The hard drives connect to a controller on the system board or a RAID controller card
through the SCSI backplane board.
The system provides several options for hard drive configurations:
l SCSI backplane daughter card (see " Installing a SCSI Backplane Daughter Card "):
¡ 1x5 configuration, without the SCSI backplane daughter card installed
¡ 2/3 split configuration, with the SCSI backplane daughter card installed
l SCSI controller:
¡ Onboard SCSI controller
¡ Optional integrated RAID controller (see " Activating the Integrated RAID Controller ")
¡ RAID controller card (see " Installing a RAID Controller Card ")
l Cabling:
¡ If a RAID controller card is not installed, no cables are required to use either the onboard SCSI controller or optional integrated RAID controller in
either a 1x5 or 2/3 split configuration.
¡ If a RAID controller card is installed, cables can be connected from the controller card to SCSIA and/or SCSIB backplane board connector(s). A
backplane board connector that is not attached to the RAID controller card will use the onboard SCSI controller or optional integrated RAID
controller.
¡ If a cable is connected to the SCSIB backplane board connector, the SCSI backplane daughter card must be installed to activate the 2/3 split
configuration. Otherwise, the system will display an error message.
See Figure A -5 to locate the connectors on the SCSI backplane board.
Installing a SCSI Hard Drive
1. Remove the bezel (see " Removing the Bezel " in "Troubleshooting Your System").
2. Open the hard-drive carrier handle (see Figure 7 -1 ).
Figure 7-1. Installing a SCSI Hard-Drive
NOTE: You should only use drives that have been tested and approved for use with the SCSI backplane board.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.
NOTICE: When installing a hard drive, ensure that the adjacent drives are fully installed. Inserting a hard-drive carrier and attempting to lock its handle
next to a partially installed carrier can damage the partially installed carrier's shield spring and make it unusable.
NOTICE: Not all operating systems support hot-plug drive installation. See the documentation supplied with your operating system.
