Re: Dasd Mod conversion mod9 to mod27
The AFAIK a V OFFLINE, a V ONLINE and a reinitialize should be all you need. If the conversion preserves the original data then REFVTOC rather than initialize should work. -- Shmuel (Seymour J.)

Yes, If they are truly empty, then reinit is good. We couldn't tell if they had data or not based on the message chain ... -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: Dasd Mod conversion mod9 to mod27
Nigel These are just a empty volumes which are mod9 and I wanted to convert them to mod27 on both DR and Production site. I believe instead of REFVTOC reinitializing the volume will do good ?

Re: Dasd Mod conversion mod9 to mod27
ICKDSF REFVTOC so that the VTOC reflects the increase in size and free space. If the volumes are in copy services relationships, they will probably need to be rebuilt and you'll need to change the size of secondary volumes. Consider the number of PAV aliases you define - maybe you would benefit from more with bigger volumes? I'd disable the volumes for new allocations while I was doing the conversion at the very least although I'd prefer to define new volumes and use something like TDMF to move the data to give the opportunity to use larger VTOC/VTOC index. Out of curiosity, why not go to 3390-54s if you have the space?

Re: Dasd Mod conversion mod9 to mod27
For the most part, z/OS versions from the last couple of decades, perform
SenseID, RDC and RCD CCWs to determine the device type and characteristics of
the device, that is the number of cylinders and if EAV is supported. That being
said, you should not have to do anything but either VARY ON/OFF or IPL.
The DS8K will report the correct number of CYLs to the OS.
Use DS QD,,RDC,RCD where is an address and the response will look like:
