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 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.
