Operating System core dumps, not always getting them!!!During driver faults
I am working in a team where sometimes the Solaris 10 OS reboots or crashes due to issues with a device driver/custom pci card the team is working on...
Recently I updated dumpadm to write Operating System "core" files to a directory/partition where there is enough space for them (if there isn't enough space the core files are not written out). However we only get the core files... sometimes... and lately NOT at all... even though we can run various tests in our system that cause the Operating system to crash the "domain" reguarly and then the OS (or we have to) does a system console setkeyswitch off, and then we/it restarts/repowers the entire box.
Anyway, does someone have suggestions as to why we don't always get a system Core file when the Operating System crashes, and what could we do to maximize the chances of this happening?
Obviously we want the OS core file to help us track down the root of the problem and fix it.
Should we find out where various driver processes are running and could we move those? perhaps to a "non-critical cpu" (just guessing here?).
?
