Chapter 4 Maintenance Guidelines
24
o Use only HP Ultra-160 SCSI LVD (1-inch) low profile 3.5-inch hard disk drives for the removable
hard disk drive cage.
o Only use an HP Ultra-160 SCSI LVD drive as the optional third drive.
o The optional HP backup tape drive comes with a 50-to-68-pin adapter to connect to the 68-pin SCSI
connector on the SCSI cable used for connection of backup tape drive.
o The optional HP backup tape drive may slow down access time for the Ultra-160 SCSI hard drives.
If this is the case, HP recommends adding another single channel SCSI controller to control the
slower backup tape drive.
Boot Priority
The HP Server tc2100 is provided in two models, IDE or SCSI, and the model type affects the boot priority.
The HP Server searches for bootable devices in a specific order, which is set up in the BIOS Utility.
IDE Model Boot Order:
1. Flexible disk drive
2. IDE CD-ROM drive
3. IDE hard drive (boot drive)
4. PCI slot P1 (32-bit slot)
5. PCI slot P2 (32-bit slot)
6. PCI slot P3 (32-bit slot)
7. PCI slot P4 (32-bit slot)
8. PCI slot P5 (32-bit slot)
SCSI Model Boot Order:
1. Flexible disk drive
2. IDE CD-ROM drive
3. IDE hard drive (if boot drive)
4. SCSI devices
5. PCI slot P1 (32-bit slot)
6. PCI slot P2 (32-bit slot)
7. PCI slot P3 (32-bit slot)
8. PCI slot P4 (32-bit slot)
9. PCI slot P5 (32-bit slot)
The SCSI Controller in the Server scans for a boot device starting at device ID 0 and works up through the ID
numbers (0-15). The SCSI controller board is always SCSI ID 7. The optional backup tape drive will use
SCSI address ID 3.
NOTE The boot order can be changed using the Server's (BIOS) Setup Utility and the SCSISelect
Utility.
