For architecture name under linux maybe "s390x" should be better,
even for IBM they specify it
as "System z" without the dash.
You are right the spelling is "System z" without the dash.
Or also s390x or s390 might be ok, if this is your standard term for
mainframe online documentation.

I assume that this is related to bugzillas 1145315 (RHEL6) / 1151895
Shouldn't the text be something like:
You have to specify all required DASDs for your kdump configuration in
the /etc/dasd.conf file.
Besides of that I think it is not sufficient to document this in
IMHO, this has to be documented in the official RHEL (kdump/dasd)
