Boot Error Report
If an error occurs, a boot error report is generated only if the Remote
Annex 2000 has opened the boot file. The report is displayed using
the following format:
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 Remote Annex 2000 generates a boot error report for the IP address
from which it tried, and failed, to boot.
The error count pinpoints 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
Last ERPC Layer Invocation lists only errors that occurred during the
failed Read Request (see
Table 4-5 ). The report does not list errors that
occurred during any other Read Request (see Table 4-6 ) or during the
Open Request (see Table 4-7 ).
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.
