SWAG without looking up the FM docs - TM == Track Managed, CM == Cylinder Managed. Given the very large "tracks used" values in that display I'm assuming that is an EAV volume.
Peter From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Frank Swarbrick Sent: Wednesday, May 21, 2025 7:39 PM To: [email protected] Subject: Volume Summary from IBM File Manager I can't find anywhere in the documentation describing what each of these fields/labels represent. I guess most are obvious, but what do "TM" and "CM" mean in this context? Also, how do I convert tracks/cylinders to bytes? One website says 56,664 bytes per track. Others say it depends on "disk type". These all seem to be defined as 3390, and another website says all 3390 models have 56,664 per track. I just want to make sure that is accurate.
