Hello,
There seems to be a bug while trying to isolate CPU using tuna-
utility on RHEL8 s380x architecture. Would it be possible to accommodate this-
bugfix in any upcoming releases? appreciate the efforts, Thanks!
Observed issue -
[root@ibm-z-137 ~]# tuna --cpus=1 --isolate
Function: isolate_cpus , Invalid argument
[root@ibm-z-137 ~]# tuna --cpus 1 --isolate
Function: isolate_cpus , Invalid argument
Expected -
[root@localhost ~]# tuna --cpus=1 --isolate
# no output, means works fine
[root@localhost ~]# tuna --cpus 1Thanks, --isolate
# no output, means works fine
Issue Environment -
[root@ibm-z-137 ~]# uname -a
