device independence is the one of the main paradigms of mvs in all its flavors

concatenation rules depend only on dataset organization and characteristics

Yes, It will give a warning but job will execute fine. It is advisable to have concat. ds on same device as it improves performance.

Correct me if i m wrong!!

And what product are you using to issue your !JCK command ?

Do you get any warning messages from JES ? or only your third party product ?

Please be sure that the information that give to others is not software dependent as this may confuse and/or irritate those that you are trying to help,

I appologize if my communication would have confused someone. I was just wondering that why do i get a warning message?

I get this message when i check for syntax errors -
CAY6098W DATA SET "A.B.C" IS CONCATENATED TO
"X.Y.Z" ON A DIFFERENT DEVICE
TYPE

When I tried to get more information from quickref by typing
QW CAY6098W on command line I get below explaination -

MVS/QuickRef 6.5
CAY6098W DATA SET DSname1 IS CONCATENATED TO DSname2 ON A DIFFERENT DEVICE
TYPE

is not your communication that' s confusing...
it' s the tool You are using that gives misleading warnings

also as a general point never reply quoting tools not available in a plain MVS
system

like fileaid/filemanager, QW, any flavor of JCL check, any in house utility,

it' s usually going to cause a flood of messages..
i don' find it
which library
and so on and so on
