Solution
Linecards have a ROMMON variable
•
DL_DISABLE depending on which line card
auto boots or remains in ROMMON waiting
for manual boot. If DL_DISABLE is set to 0,
line card does not boot automatically but
waits for the user to manually boot with
respective line card image (from line card
console). Line card auto boots only if
DL_DISABLE=1. When DL_DISABLE=0
and line card doe not initialize, SCP
Keepalive Failure messages appear on RP
console.
• A line card is reset by the SP with messages
that SCP download failed or module reloaded
during reset. This occurs at the time of bootup
with a heavy configuration and a many line
cards. Execute the debug cwan oir command
to check the RP status. When a line card sends
a Find Master to the RP, some of the messages
are sent to SP to confirm if the module is
online. If the message fails to reach the SP,
then SP resets the module with message that
SCP download has failed. If the line card,
does not receive the response in the time, the
line card resets itself.
Reload the line card and connect the LC
•
console and check the status. If there is a
problem with ROMMON download of the
image from the SP, then the ROMMON of the
line card should then be upgraded to the latest
version. If a bay crashes, collect the stack
trace to identify problem.
