Yes John ,but somehow no :-)) But as i said it was for the sake of the argument . In my case ,I run a // sysplex on 2 distant sites I have protected my environment against hardware failure by PPRCing (synchronous) the entire siteA DASD bay on siteB bay . If a plane strikes ( forget the laser beam :-) ) one of my bay,i am OK,i still have my site B with proper data because device end comes back only once secondary is written . If some human/application/whatever accident erases my data , i am dead . For these reasons i need some DR backup , and some legal rules oblige me to have these cartridges externalised . To do that , i need a mean , and the easiest way is Db2 log suspend followed by flashcopy and Db2 log resume then dump my flashcopied disks . ( Joel C. Ewing gave a vey nice description of why we cannot make it without log suspend) But as Ron said , Disks are pretty strong these days , raid 5 and 6 are nice securities , etc etc ...
