Method to force system dump to collect all data without further manual intervention to reset the overrides

Disclosed is a method for control of overrides of system dump contents without further manual intervention to reset the overrides.

When there is a computer server fail, data collected by a system dump might be insufficient to debug the issue. Proposed is an override to collect all entries in a hardware dump content table (HDCT).

A current solution is to come up with a custom HDCT that is tailored for each fail by adding the missing hardware data, which needs to be integrated into a one-off firmware build. The firmware build then needs to be tested before being released to the customer. This process can take multiple weeks, if not months, causing precious time to be lost before resolving the problem.

When a server fails, related error information is collected in the form of system dumps. The contents of each system dump depends on what type of fail was observed. HDCT determines which processor and/or asic chip registers and facilities are collected for each fail. Since each fail scenario cannot be foreseen, sometimes one will end up with insufficient data to debug the fail.

Instead of waiting for a custom firmware build for each case, it is proposed to use an override to dump all the entries in HDCT regardless of the type of fail. This can decrease turnaround time from weeks to days.

Another option for dumps can be used that gives the choice to force a user dump in te...
