Boot Error Report
If a boot error occurs, a RAC boot error report is generated only if the
RAC opened the boot file. The report looks similar to this:
BOOT ERROR REPORT (for BFS files only)
Boot attempt from host nn.nn.nn.nn:
Errors from Last Open Request:
0 ARP errors 0 ERPC layer errors 0 Aborts rx’d
Errors from Last Read Request:
0 Msgs w/ wrong size 0 ERPC layer errors 0 Aborts rxd
Errors from Last ERPC Layer Invocation:
0 H/W errors 1 Msgs from wrong host 0 Rsp T/O’s 0 Msgs of wrong type
TFTP error reporting complies with the standard, predefined
TFTP error codes.
The RAC generates a boot error report for the IP address from which it
tried to boot.
Table 4-6 contains a description of the errors from the last
ERPC layer invocation field; Table 4-7 contains a description of the errors
from the last read request field.
The error count indicates the error that caused the boot failure. For
example, if the boot failed during a read request due to excessive
Expedited Remote Procedure Call (ERPC) layer errors, the errors from
the last ERPC layer invocation field lists only errors that occurred during
the failed read request (
Table 4-6 ). The report does not list errors that
occurred during any other read request ( Table 4-7 ) or during the open
request ( Table 4-8 ).
The open request and the read request layers communicate with the block
file server (BFS) on the host. The ERPC layer resides below the open
request and the read request layers. It is responsible for sending a given
message to a specific host UDP port, and for receiving the correct
response to that message from the port.
