Externally Initiated Reset XIR

If a hard failure occurs, use XIR to reset the system and get information about the system state at the time of the hard failure.

To Initiate an XIR

1. Use either the XIR button on the clock board or the remote console XIR sequence.

   When an XIR occurs, memory is cleared but some CPU state is saved.

To Display this XIR Information

1. Type the following command at the ok prompt immediately after the XIR:

   ---

   ok .xir-state-all
   

   ---

   The output displays the CPU state for each CPU:

   #1 ok .xir-state-all

   TL=1 TT=3

   CPU ID#1

   TPC=e0028688 TnPC=e0028688 TSTATE=9900001e06

   CPU ID#5

   TL=1 TT=3

   TPC=e002755c TnPC=e0027560 TSTATE=4477001e03

   #1 ok .xir-state-all

   TL=1 TT=3

The XIR does not override the NVRAM auto-boot? variable.
