Invalid linkmode If no errors are found, the condition code is set to zero. I/O Interruption I/O interruptions from completed I/O operations initiate various
coapletion routines and the scheduling of furtherI/O requests. The I/O interruption handling routine also gathers device sense information. Machine Check Interruption When a machine check occurs, CP Recovery Management support (RRS) gains
control to save data associated with the failure for FE aaintenance.R!S analyzes the failure and determines the extent of daaage. Damage assessment results in one or more of the following actions
being taken:• Systea teraination • Attached processor varied offline (systea converts to uniprocessor
aode)• Virtual user running at the time of error is terainated • Refreshing of
configurationdaaaged infor.ation with no effect on systea • Refreshing of daaaged inforaation with the defective storage-page
removedfrom further system use • Error recording only for certain soft aachine checks
Thesystem operator is infor.ed of all actions taken by the RRS routines. ihen a aachine check occurs during VR/370 startup (before the system is set up well enough to perait RRS to operate successfully}, the
processor goes into a disabled wait state and places a coapletion code
ofX'OOB' in the leftaost bytes of the current PSi. CP Introduction 1-73
