arp/rarp timeouts when attempting to boot from disk
DETAIL DESCRIPTION:
Boot fails with error "Timeout waiting for ARP/RARP packet"
as the user attempts to boot from a disk boot device. This
error indicates that the system is actually trying to boot
over the network.
This problem most commonly occurs after installation of a new
system, after a PROM upgrade, or after replacement of a cpu board.
SOLUTION SUMMARY:
There are 3 possible solutions:
1) Verify that the OBP environment variable "diag-switch?" is set to false.
If diag-switch? is set to true, extended post diagnostics will be executed
followed by an attempt to boot from the "diag-device" alias which is set
to "net" by default.
Check the value of diag-switch?:
ok printenv diag-switch?
diag-switch? = true
Fix:
ok setenv diag-switch? false
ok reset
2) The system's key switch is set to the diagnostics position. This is
the equivalent of having "diag-switch?" set to true. The diagnostics key
switch position is labelled similar to a ~ character.
Fix: Set the key switch to the on position (labelled with a vertical bar).
3) The OBP "boot-device" alias is set to "net" or "net" is in the list
of "boot-device" aliases to attempt to boot from and the previous boot
devices cannot be accessed.
Fix:
ok setenv boot-device alias
(where "alias" is an alias for the correct boot device)
ok reset |
