Redbook : System z Mean Time to Recovery Best Practices

"It is interesting to note that I can IPL my production LPAR faster than I can boot my windows pc !" (Comment by Don on this Redbook)

Just drawing your attention with a little quote. This draft has been out for a good month now and only looking at the objectives tells you that this book is definitely worth your while :

• "Minimize the application down time that might be associated with planned system outages.
• Identify the most effective way to reduce MTTR for any time that you have a system IPL.
• Identify things that are under your control and that can make a worthwhile difference to the startup or shutdown time of your systems.

MTTR basically "covers the time period from the instant you start your shutdown process, through to the point where the online applications are available again". This is illustrated below.


Looking at the contents gives you a good impression of the topics that are being discussed.
