Board numbering
When a system with multiple Osprey boards is first set up, the device numbers reflect the order that
the system identified and initialized the boards. The driver associates each device number with the
PCI address of the board to which it is initially assigned, and saves that information. Each time you
restart the system the same associations are preserved.
This initial ordering might not be the order you want. For example, in a system with four boards you
may want the boards ordered 1-2-3-4 from left to right or top to bottom of the chassis.
Click Board Numbering on the Device tab to display the Board Numbering window (Figure 33) for
renumbering the boards.
Figure 33. Board Numbering
Each line represents the information for one Osprey board. Only boards that are currently installed
and enabled appear. Also, only boards of one type at a time appear. For example, consider a system
with two Osprey 230e and two Osprey 440e boards. The two board types are numbered separately
– there is a board 1 and a board 2 of each kind. Which listing is shown depends on the context in
which you open the property pages. If you open them from an Osprey 230e context, you see the
two Osprey 230e boards. If you open them from an Osprey 440e context, you see the two Osprey
440e boards.
The information for each board includes the PCI bus and device address on the left, the serial
number in the middle, and the current device number on the right. For boards such as the Osprey
440e which span multiple PCI addresses, the PCI Bus/Slot information does not display.
You can edit the device numbers. You can assign each board any number from 1 to 64. All boards in
the current list must have different numbers. The numbers do not have to be in a packed sequence
1, 2, 3…
