Symptoms


A Sun Fire[TM] 12K/15K/E20K/E25K domain is issued the command reboot, init 6, or a "halt + boot" and it goes down to OBP. It starts the process of "Resetting" where it sits indefinitely. No post log is generated and no HPOST process is ever run for this domain. A manual setkeyswitch off and on for the domain finally brings it back up with no issues. Here is an example of this issue taken from a real case:


The customer entered the init 0 and then issued the boot command. The domain sat at "Resetting" for almost 45 minutes before the customer finally intervened with the setkeyswitch off and on to restore the domain to the OS. Afterward, the customer issued a reboot to see if the issue was only with "init 0 + boot". It was not; the reboot also hung at "Resetting...".
