SCSI PCI HBA Documentation Correction
An error exists in the current manual for each of these SCSI PCI Host
Bus Adapters (HBAs): A5150A, and A5159A
In the chapter about installing the adapter, under the heading “Setting
the SCSI IDs,” the first paragraph states that if you will be booting the
system from a SCSI disk drive on the SCSI bus, you should give that
drive the lowest SCSI ID on the bus. This is not correct.
The correct instruction is as follows:
If you plan to boot your system from a hard disk drive on the SCSI
bus, you should assign that drive the highest priority available on the
bus. A device’s priority is determined by the device’s SCSI ID. The
order of the SCSI ID priorities (from highest to lowest) is 7, 6, 5, 4, 3,
2, 1, 0, 15, 14, 13, 12, 11, 10, 9, and 8. So, a device with SCSI ID 7 has
the highest priority, and one with SCSI ID 8 has the lowest. Note
that SCSI HBAs should always have the highest priority SCSI ID.
The following manuals are affected:
• HP A4800A PCI FWD SCSI Host Bus Adapter Service and User
Guide (A3725-96031, E0201), page 30
• HP A5149A PCI Ultra2 SCSI Host Bus Adapter Service and User
Guide (A5149-96003, E0201), page 31
• HP A5150A PCI Dual Port Ultra2 SCSI Host Bus Adapter Service
and User Guide (A5150-96002, E0201), page 35
• HP A5159A PCI Dual Port FWD SCSI Host Bus Adapter Service and
User Guide (A5159-96002), page 31
