Boot Error Report

If an error occurs, a Remote Annex 6300 boot error report is generated only if the Remote Annex 6300 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 6300 generates a boot error report for the Internet address from which it tried, and failed, to boot. Table 4-7 contains a description of the Errors from the Last Read Request; and Table 4-6 contains a description of the Errors from Last ERPC Layer Invocation.

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 4-6). The report does not list errors that occurred during any other Read Request (see Table 4-7) or during the Open Request (see 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.
