We once lost a memory card on a 9672. I think it
was an R44 at the time. The whole box crashed (VM in basic mode).
Luckily it was a Saturday morning. CE came in and brought it back up minus
1/2 the memory until a new card could arrive on Tuesday.

Subject: [IBMVM] Memory Reliability
In all my years working with IBM mainframe systems I have never seen a memory failure that caused recognisable problems.
My understanding is that the internal redundancy, hardware checking and auto correct make such an event very unlikely - but how unlikely? Has anyone ever experienced such a problem?
If a problem did occur at the level that affected VM would it be more likely to bring VM down or just affect a specific user referencing the memory blocks with the problem ?
Regards
Colin Allinson
