Your system features ten standard internal SCSI hard-drive bays. Systems with an optional RAID controller card or optional ROMB support hot-plug SCSI drive operation.
The system's two peripheral bays can accommodate up to two 5.25-inch form-factor devices (such as tape drives) or an optional 1x2 SCSI backplane to enable installation of two additional SCSI hard drives.
Installing SCSI Hard Drives
Figure 7-1 shows the SCSI ID numbers of the ten standard drive bays. (SCSI ID 6 and SCSI ID 7 are reserved for use by the system's integrated SCSI host adapter and SCSI enclosure management controller.)
Figure 7-1. SCSI ID Numbers for the Standard Hard-Drive Bays
Before You Begin
SCSI hard drives are supplied in special drive carriers that fit in the hard-drive bays.
NOTICE: Before attempting to remove or install a drive while the system is running, see the documentation for the optional RAID controller card or optional ROMB to ensure that the host adapter is configured correctly to support hot-plug drive removal and insertion.
NOTE: It is recommended that you use only drives that have been tested and approved for use with the SCSI backplane.
You may need to use different programs than those provided with the operating system to partition and format SCSI hard drives.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.
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. A 9-GB hard drive, for example, can take up to 2.5 hours to format.

came with the drive.
Unpack the tape drive (and controller card, if applicable) and configure the tape drive
according to the documentation that came with the tape drive, based on the following
guidelines:
Each device attached to a SCSI host adapter must have a unique SCSI ID number. Set
the drive's SCSI ID to avoid conflicts with other devices on the SCSI bus. For the default
SCSI ID setting, see the documentation provided with the drive.
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.
SCSI logic requires that the two devices at opposite ends of a SCSI chain be terminated
and that all devices in between be unterminated. Therefore, you enable the tape drive's
termination if it is the last device in a chain of devices (or sole device) connected to the
SCSI controller.
If a controller card was included in the drive kit, install the card now. See "Installing an
Expansion Card" in "Installing System Components."
