You can check https://access.redhat.com/solutions/2437991 &  https://access.redhat.com/solutions/3014361 You have 2 options: 1. Set a udev rule like this one (replace NETAPP with your storage) ACTION!="add|change", GOTO="rule_end" ENV{ID_VENDOR}=="NETAPP*", RUN+="/bin/sh -c 'echo 4096 > /sys%p/queue/max_sectors_kb'" LABEL="rule_end" 2. Set max_sectors_kb in devices  section of multipath.conf You will need to stop LVM and then flush the device map , so the new option to take effect (faster  is to reboot) Good Luck  & Happy New Year.
