Boot Failures
Micro-CS Installation Guide 4-7
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. The report does not list errors that occurred during
any other Read Request or during the Open Request.
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.
Table 4-5 Errors from Last Open Request
ARP errors
Address Resolution Protocol (ARP) errors indicate that
the Micro-CS is configured to boot from a specified
host, but the host would not transmit its Ethernet
address to the Micro-CS. Possibly, the Micro-CS
configuration includes the wrong IP encapsulation.
ERPC layer errors See Errors from Last ERPC Layer Invocation below.
Aborts rx’d
The host’s BFS transmitted an abort in response to the
Micro-CS’s Open Request. This often means that the
requested file does not exist on that server. Run
erpcd -D on the host to obtain more information.
Table 4-6 Errors from Last Read Request
Msgs with wrong
size The correct host responded to the Read Request, but
the data size is incorrect.
ERPC layer errors See Errors from Last ERPC Layer Invocation below.
Aborts rx’d
The host’s BFS transmitted an abort in response to the
Micro-CS’s Read Request. Run erpcd -D on the host
to obtain more information.
