core
• OFF 00800 Reset System (cannot be turned ON)—the system reset triggered by the resetsys
command
• OFF 01000 Switch Core Card—the reset caused by the switchcc command (core card switch-over)
• ON 02000 Secondary Cache Error
• ON 04000 Software Error Reset
• OFF 08000 S/W reset due to upgrade (cannot be turned ON)
• OFF 10000 Restore All Configuration (cannot be turned ON)
• ON 20000 Device Driver Error
If you add all the reset reasons that are ON in the default mask, the sum is the hexadecimal number
262ee. A reason that cannot trigger a core dump is indicated in the preceding list with “can't be turned
ON.” A reset reason that cannot trigger a core dump removes pertinent information from memory.
Redundancy Policy
After a redundant pair of service modules switches over, the former active card is rebooting, so a core
dump is possible. Because the activated card is carrying the traffic, the time to write RAM contents from
the reset card to disk normally is not an issue. For non-redundant service modules, however, the dump
time may be a concern. The parameters for redundancy policy let you determine whether core dumps can
occur in non-redundant service modules.
The redundancy policy is a node-level configuration. You can override the configuration on a per slot
basis by enabling or disabling core dumps at the CLI of the individual card.
Aborting a Core Dump
In some circumstances, you would want to abort a service module core dump. Example situations follow:
• Two or three core dumps begin, but you do not want the switch to take the time or resources to
complete these processes. Additionally, one core dump may be crucial, so to ensure that it does not
time out, you could abort one or two of the other core dumps.
• You could have removed redundancy from a pair of card slots but did not disable core dumps on a
card where you do not want core dumps. If a core dump begins at such a slot, you can abort the core
dump from the PXM then change the configuration on the service module after it comes up.
