Hi Guys, I am getting problems with configuration of multipath on system z (SUSE 11 SP4 - kernel 3.0.101-94).
I have 4 paths to disk access and today a path was down and multipath not work properly. Then server was down with high usage of CPU and i/o wait. Config of multipath: features "0" prio alua failback immediate rr_weight uniform no_path_retry fail path_grouping_policy multibus dev_loss_tmo 300 fast_io_fail_tmo 25 path_selector "round-robin 0" rr_min_io 1 Server using WAS application and high usage of i/o. I solved the problem when i did a flush/down on path with issue.
