Can I inactive the Primay ( switch CDS1 with CDS3?) and then delete CDS1 and use IXCL1DSU to create/format it fresh? Or do I need to just create a new pair and activate them instead and junk my original pair? Is there anything special about the type of CFRM that I need to take into consideration when Switching and Del/Def? (Yes I am using the IBM Utility to do this work) > You can reformat any CDS that is not currently in use. Simply delete CDS3, then run the IXCL1DSU utility to reformat it with the desired number of structures per policy. Then bring it into service as the alternate: SETXCF COUPLE,TYPE=CFRM,ACOUPLE=(cds3 dsname,volser if not catalogued) This will remove your original alternate (CDS2?) from service, so you can delete and reformat it. Then promote CDS3 to primary: SETXCF COUPLE,TYPE=CFRM,PSWITCH This will remove your original primary (CDS1?) from service, so you can delete and reformat it. Then restore the desired CDS configuration with the appropriate SETXCF COUPLE ACOUPLE / PSWITCH commands as above, for instance: SETXCF COUPLE,TYPE=CFRM,ACOUPLE=(cds1 dsname,volser) SETXCF COUPLE,TYPE=CFRM,PSWITCH SETXCF COUPLE,TYPE=CFRM,ACOUPLE=(cds2 dsname,volser) Now you have your original CDS configuration restored, except that all CDSes have been reformatted for the greater number of structures. > 2) When I do the SETXCF COUPLE command is the PSWITCH on the TYPE= or other? > SETXCF COUPLE,PSWITCH,TYPE=CFRM,PCOUPLE=(CDS02),ACOUPLE= (CDS03) or > SETXCF COUPLE,TYPE=CFRM,PCOUPLE=(CDS02),ACOUPLE=(CDS03),PSWITCH See the syntax above. It's documented in System Commands, see http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2G133/4.46.3?

Any time, but as with any other system modification it's prudent to do it when nothing else significant is going on, particularly anything that affects CFRM like rebuilds, IPLs, partitioning, etc. > 4) Any other suggestions? > Bill Neiman z/OS Development ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
