The customer presented ScaleIO "scini" devices as multipath devices in their RH server using KB: 000484523
When the customer added the (scini)disk device entry in the /etc/fstab and rebooted the host, the server will not reboot.
If the customer removes the fstab entry, the system boots up and the 'multipath -ll' entry shows the scini disks.
The _netdev option is required when mounting Dell EMC SIO devices at boot time.
This is because the network needs to be up so the host can access the SIO volumes.
The _netdev option prevents the filesystem from being mounted until the network is available.
SIO devices should be mounted with _netdev option in /etc/fstab to permit boot-time fsck.
Linux Man entry for _netdev:
_netdev: The filesystem resides on a device that requires network access
(used to prevent the system from attempting to mount these file systems until the network has been enabled on the system).
