<div dir="ltr"><font face="Default Monospace,Courier
New,Courier,monospace" size="2">Not required. Check the
condition again (The line which says 'if not is_s390x()').
Only if the platform is s390x it will enter the code
path where 'dir_path' is checked so there is no need to
check for s390x arch again. I have tested this flow on x86
as well as on s390x, and it works fine.</font></div>

Sorry but how the first condition is related to the second one?!<br>
<br>
If I am x86 and I have specified a 'vol' or a 'path' and not a
'dir_path' as it is exclusively for s390x, it will raise the
dir_path exception (the second condition).<br>
<br>
So or you add a is_s390x() condition to the second statement or you
place the whole first block in a if conduction:<br>
<br>
if not is390x():<br>
if not (vol in params) ^ (path in params):<br>
(...)<br>
else:<br>
if dir_path not in params:<br>
raise ...<br>
