Last night (well, way into this morning) we had a severe WTO buffer shortage that nobody saw. Here's why:
*IOS071I 0500,**,CONSOLE, START PENDING 378 *IOS002A 0500,NO PATHS AVAILABLE IOS2002I 0500 NO PATHS AVAILABLE 381 STATUS FOR PATH(S) ED SUBCHANNEL PATH AVAILABLE, BUT DEVICE NOT OPERATIONAL (C0) NO FURTHER INFORMATION AVAILABLE OR UNKNOWN CONDITION (FF) 3.5 hours later: *IEA405E WTO BUFFER SHORTAGE - 80% FULL IEE889I 01.04.41 CONSOLE DISPLAY 111 MSG: CURR=2401 LIM=3000 RPLY:CURR=18 LIM=99 SYS=yyyy PFK=00 xxxxxx 46 COND=A AUTH=MASTER NBUF=2390 0500 AREA=Z,A MFORM=T,S,J xxxx DEL=RD RTME=1/4 RNUM=15 SEG=14 CON=N K S,DEL=R,L=xxxxxx IEE151I DELETE REQUEST INCONSISTENT-NO DISPLAY ON SCREEN COMMAND ISSUED IS K E,D,L=xxxxxx Severe WTO buffer shortage a short while later. No other IOS messages or CNZ messages (no cnz messages before the buffer shortage) until the console was varied online again *hours* later (while still in severe wto shortage): V 500,ONLINE IEE302I 0500 ONLINE LOGOFF - ISSUED BY IEECVFTG IEA406I WTO BUFFER SHORTAGE RELIEVED At the time of the IOS002A another system in another sysplex but on the same box got this: *IOS050I CHANNEL DETECTED ERROR ON 0500,**,**,**04 CNZ4200I CONSOLE zzzzzz HAS FAILED. REASON=IOERR Now my question (mainly to IBM - will probably be faster than going through a tedious ETR): Why the heck isn't the console address space notified that no paths are available? Why is the console address space still issuing messages to that console? Why isn't console notified that the console 500 is not availabe anymore? Nobody was able to even *see* the shortage messages since nothing got displayed on that console anymore!!!! And if this is broken as designed, will I have to code an mpf exit that makes sure all buffer shortage messages will be sent to all consoles in the sysplex? Operators will be extremely happy about that (since many don't even know where to see which system issued the message- reading a formatted syslog message appears to be a dying/lost art).
