Boot Priority - HP NetServer LC 2000r Installation Manual

Boot Priority

This section details the HP NetServer's boot order by highest to lowest priority.
The NetServer's boot order (BIOS search order for a boot drive) should be
considered when selecting a slot on the system board. This is especially important
if you are installing a SCSI disk controller board. The disk controller's boot
priority is set by the board's slot location. See Figure 6-1.
The on-board SCSI consists of two channels, A and B. Channel A is typically
used to control the Hot Swap SCSI drives. Channel B is typically used to control
the internal non-hot swap SCSI drives. On each SCSI channel, the system scans
for a boot device starting at device ID 0 and works up from there.
By default the NetServer searches for boot devices in this order:
1. IDE CD-ROM drive
2. Flexible disk drive
3. SCSI A bus (typically the Hot Swap Mass Storage Cage)
4. SCSI B bus (typically the non-Hot Swap internal SCSI devices)
5. PCI slot P1
6. PCI slot P2
7. PCI slot P3
8. PCI slot P4
9. PCI slot P5
10. PCI slot P6
NOTE The NetServer can be configured to boot from a PCI accessory
board or PCI-based DAC, instead of the onboard SCSI
channels, by putting the board in one of the PCI slots. The
SCSI Configuration Utility can be used to configure the
NetServer to skip over the onboard SCSI channels and select a
PCI slot instead, when scanning for boot devices. For
instructions, refer to the SCSI Configuration Utility in Chapter
10, "Configuring the HP NetServer."
