Hi,

So far, we have changed how we mount and unmount the disks. By doing so,
we have not had the high CPU usage issue again.

We currently do more checks before mounting the disk. Before we used to mount 
without checking if the device was actually visible. 
we umount the old disk
sudo /sbin/multipath -F
sudo systemctl daemon-reload
sudo /usr/bin/iscsiadm -m session --rescan
sudo /sbin/multipathd reconfigure

sudo /sbin/multipath -ll | grep SCOMPELNTCompellent_Vol. => if exit code
is 0 we restart the process with a flush -> reload-> rescan->
reconfigure


otherwise we continue and we check for if our device is already visible

sudo /sbin/multipath -ll |grep' , volumeToMount deviceId. => if exit
code is 0 we mount it


by following this procedure, we did't had anymore issues with the 
multipathd/nor CPU usage.
