There is a discussion of I/O priority in the Channel Sub-system in the

Thank you David, John and off-list contributors for providing useful 
information. Reiner Markus's query about STORAGESERVERMGMT had made me curious 
about how I/O Priority Queuing is implemented in channel programming.

Well there is/was an ESS reference SC26-7298 which I downloaded quite some time 
ago, it's available here 
http://ebookbrowse.com/ess-s390-command-reference-exxfxx-sc26-7298-01-pdf-d170380434
 for example (not sure how legal the site is). However there's stuff which is 
no longer documented at least without NDAs and payments to IBM and many of the 
commands tend to get converted to something else before reaching the controller 
nowadays anyway. As far as the actual everyday CP commands are concerned 
there's not very much difference I think to your manual. The Share document 
"zHPF Channel Programming The Bits and Bytes" by David Bond which one can find 
online might be an interesting introduction for those who want something newer.

Hello List,

Can somebody provide me with a URL or publication number for the manual that 
describes the MVS (CKD) channel commands supported by the IBM System Storage 
DS8000?

The most recent channel commands reference I can find is GA32-0274-05, which is 
ancient.

Thanks,
Alan

Shmuel is quite right.

To get the information you want you will need to enter into an IBM
System Storage DS8000 License Machine Code Agreement with IBM and pay
a fee.

You can download a copy of this agreement---The publication number is
GC26-7918---from the IBM Publications Center.

First, they're not specific to MVS. Second, it's been a long time
since IBM has disclosed the details of all new channel commands for
their DASD.
