CA-1 also records the IDRC compression ratio. This makes it possible to calculate the real amount of data written to a cartridge.

Since this does not take into account compression it does not show the amount of physical tape cartridge consumed. Maybe this is in the IBM tools, but I am not familiar with them Carl Swanson Mobile:215.688.1459 Email: [email protected] -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Lizette Koehler Sent: Tuesday, July 09, 2013 9:04 AM To: [email protected] Subject: Re: Method to measure usage of a physical tape CA1 records block size and how many blocks. Then you can calculate the size of the file. What type of tape are you using, and are you trying to use tape efficiently, i.e. no wasted space on tape? If so, the IBM Tapetools will be very helpful. ftp://ftp.storsys.ibm.com/tapetool/updates.txt http://public.dhe.ibm.com/storage/tapetool/overview.pdf http://public.dhe.ibm.com/storage/tapetool/ Lizette -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Victor Zhang Sent: Tuesday, July 09, 2013 5:56 AM To: [email protected] Subject: Method to measure usage of a physical tape Hello all, I am using physical tape drive with high capacity which connect via FICON director with CPU,there is no virtual tape storage used, data is directly backed to physical tape drive,my question is how can I determine how much space used for a given physical cartridge? Does TMS software record this?
