5.2.3.2 Shelf Address Reading Behavior
This subsection describes different scenarios for the reading of the shelf address by the FRUs
during system power-up. What happens if
 none of the shelf manager boards are accessible via IPMI?
 both shelf manager boards are accessible via IPMI but have different SGA settings?
 a shelf manager is replaced?
None of the shelf manager boards are accessible via IPMI
If the SGA has already been successfully read and cached in the SAM1410 shelf managers
before the two SAM1410 became unavailable, the SAM1410 uses this correct SGA. This means
that the SGA is not lost if both SAM become unavailable.
If the SGA has not already been successfully read before the two SAM1410 became unavailable,
the SAM1410 will not come up and the red LED will stay on.
Shelf Manager Boards have different SGA settings
If both SAM1410 are accessible via IPMI but have different SGA settings, the SAM1410 will not
come up and the red LED will stay on. In this case. remove one SAM1410 and boot the system.
Once the HPI daemon on the SAM1410 is up and running, the second SAM1410 can be
installed. It will assume the SGA from the first one.
Shelf manager replacement
If a shelf manager needs to be replaced, you need to wait for approximately 3 minutes after
shelf manager board insertion untill the HPI daemon is up. You then need to reboot the shelf
manager to make sure that the correct SGA is applied to the network settings.
5.2.4 IP Addresses
The following subsections describe the IP addresses of the shelf manager and the hub blade.
There are no pre-defined IP addresses for the node blades.
