Size of what? Data written to tape? Space allocated on tapes? Depending on compression setting, you may wish to check mminfo manual and certain parameters for reporting like totalsize. From there, some basic and advanced calculations can be made.

Hi

Data written to tapes.
There are two parameters, Totalsize and Sumsize, what is the most precise?
The byte their unit is it.

Best regards

sumsize will give you size per tape, while totalsize total size of ssid. Thus I would use totalsize (make sure not to use in report something that would give you per tape report otherwise you will get repeated values which you will have to address through sumflags).

Totalsize is given in bytes by default, but if you set spacing to be 1 you will get it in more friendly readable format (even for calculations I would keep it in bytes).

I think that the parameter Sumsize will be a solution for me, because I want the data size by pool (some tapes).

Thanks
