For those that got post forwarded and can't see the recent URL refs on garlic.com ... On 17Apr2015, garlic.com changed there webserver and still have yet been able to update my personal web pages ... to see the full thread check google group archive. https://groups.google.com/forum/#!topic/bit.listserv.ibm-main/K2Elt-40-VE With regard to MVS MTBF 15min, I happened to mention in an internal (only) report giving technical details of building a bullet proof and never fail I/O subsystem ... which brought down wrath of the MVS organization on my head ... apparently they would have gotten me fired if they couldn't figure out how ... but they found other ways of taking out their displeasure. VM370 official calypso support, put8201, reference to retrofitting to heavily modified internal system.

What do you think? ... snip ... from vmshare archives ... discussion of 3880 speed matching buffer but doesn't explicitly say anything about define extent and eckd http://vm.marist.edu/~vmshare/browse?fn=3380&ft=MEMO old email about FE error injection regression tests for 3380 ... all of the 57 errors were resulting in MVS hanging and requiring reipl and in 2/3rds of the cases, there was no indication of what caused the problem (this is separate from the earlier issue where they attempted to use MVS in the bldg. 14 engineering test lab and found it had 15min MTBF) http://www.garlic.com/~lynn/2007.html#email801015 -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
