Re: DEVTYPE INFO=DASD
The result I get from the same DEVTYPE macro is: FFF0 000F F000 01000800 which differs from the OP in that there are 2 more bytes at the beginning in my case. My results have a fullword for the number of cylinders and a fullword for tracks per cylinder, which agrees with all of these manuals: z/OS 1.10 http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/DGT2S350/7.2.1.5 z/OS 1.13 http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/DGT2S380/7.2.1.5 z/OS 2.1 (page 272) http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/download/DGT3S300.pdf I think the OP is just looking at the wrong address, 2 bytes beyond the correct address.

Re: DEVTYPE INFO=DASD
I sent in an RCF this morning with what I thought the book should say, and copied the lead DADSM/CVAF developer (to make sure my correction does not inject some different problem!).

I think the possibility should be considered that the OP may have mistakenly been looking at the 16 bytes at AREA+2, not AREA. If that happened, and the missing bytes are hex , the results would be correct for a device with 65520 cylinders.

DEVTYPE INFO=DASD
Hi I was looking for the capability on a dasd device DEVTYPE (R6),(AREA,L'AREA),INFOLIST=ILIST2 ILIST2 DEVTYPE INFO=DASD AREA DSXL16 This was the data returned in area R15 = 0 FFF0 000FF000 0100 0800 DASD Returns 16 bytes as follows: Bytes 0-3 Number of cylinders on the device, excluding alternates. For a VIO data set, this number is the number of simulated cylinders needed to contain the data set. Bytes4-7 Number of tracks per cylinder. Seems to indicate over 4 million cylinders and over 100,000 tracks on the volume ?
