NFT Reference Manual
SETCOS (Change Storage Class of Service)
You can check the current COS setting for your NFT session with STATUS. STATUS dutifully reports any integer nnn that you supply with SETCOS, even if not allowed by HPSS. And when STATUS reports a COS of 0 (zero), HPSS automatically sets each stored file's COS based on its size according to the default behavior.
You can discover the COS with which already stored files have been stored by using NFT's DIR command with the -h option (COS then appears in the third column in DIR's report). See also the detailed class of service discussion in LC's HPSS Reference Manual.
