This thread has begun with a PPRCopy question. I am not sure if this two parts of Bruce' mails (not to cite John and Ron) talk about PPRC (Truecopy) or Flashcopy (Shadowimage). I wasn't able to see any of these features in our z/OS 1.7 PPRC environment using HDS 9980.
<----- snip -----> You don't need to lose the relationship to do the backup. You probably want to backup a point-in-time copy of the volumes, so you can just SUSPEND the PPRC relationship. This freezes the copy and makes it read/write so you can relabel (CLIP) it. After the backup, you can RESYNC the PPRC copy, which just copies tracks updated since the SUSPEND. <----- snip -----> Supposing we do it in a z/OS 1.7 system I don't understand how is it possible to clip the secondary volume. I get the info about the device being a PPRC secondary device. Even if I take the primary volume offline, I get the same kind of message if I try to take the secondary volume online. Bruce wrote: <----- snip -----> I believe that RESYNC will copy any tracks which have been modified on the source OR target. <----- snip -----> The other thing that I don't understand: To be able to write on the secondary volume, I suppose I have to use CDELPAIR or at least CRECOVER. If I use CDELPAIR, I can not RESYNC anymore. If I use CRECOVER the secondary volume switches in the SIMPLEX status, so how comes its bitmap is updated?
