What problem are you trying to solve? most shops use a stand set of definitions for dasd which comes with specific setting for size of volume.
So if you see it is a 3390 Mod3 you know it will be 3339 cylinders. Though you could make it different, this is what most will recognize as how many cylinders are on a Mod3. With EAV the type of volume definition is slightly different and IBM has suggested 3390 ModA (3390-A) for EAV. Then you would specify how large it is (typically larger than a Mod54) You also need to see that the Mod-A uses a different sizing - it can be up to 255TB in size for one volume If you do an internet search on IBM 3390-A EAV You might find this Share presentation that might help SHARE 9941 Planning for EAV Migration Or this IBM Redbooks | DFSMS V1.10 and EAV Technical Guide Or this entry Extended address volumes for CKD - IBM They (and other presentations and links) should help you understand the EAV Lizette > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] On > Behalf Of Jake Anderson > Sent: Wednesday, July 19, 2017 1:57 AM > To: [email protected] > Subject: Identify EAV volume > > Hi > > Is there any command to identify if a particular volume series belongs to EAV > ? > > Any commands or macro which can help ? > > Regards > Jake > ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
