Need help to convert BLKSIZE to Tracks/CYL for SFTPing

Hi,

I am trying to use SFTPPROC to transfer files from X LPAR to Y LPAR, I need help in allocating the space parameter to transfer the file successfully.

My SFTP process fails due to space parameter-which i have not allocated it correctly.

FILE A : SPACE=(27930,(500,50),RLSE) (On X LPAR)
to be transferred to Y LAPR using SFTPPROC with below options

ls /+lrecl=133,recfm=fbm,space=cyl.500.50,unit=DDDD

Can someone help me to convert (27930,(500,50),RLSE) to tracks/cyl?

I need to be precise with the allocation of the files being transferred, Job failed in prod when i gave random allocations due to excessive or less space allocated.I have multiple files defined in BLKSIZE which need to be transferred via SFTP process,So i need to provide appropriate allocations.

Thanks in advance!!

BLKSIZE=27930 equates to 2 records per track.

Emulated 3390 devices always have 15 emulated tracks per emulated cylinder.

Remember these lines.

so SPACE=(27930,500) becomes the equivalent of SPACE=(TRK,(13965,250))
or SPACE=(CYL,(931,17))

27930/2 = 13965 500/2 = 250 13965/15 = 931 250/15 =17

2 physical records per track, which, of course, is the same as 2 blocks.
