Failover failure with Netapp in ALUA mode

Issue

• There was a migration on a Netapp filer where in the activities were included some failover and failback tests, but when we performed those activities the servers involved were not able to support the failover.
• After updating the kernel for ALUA, failover took too long for our cluster, causing a reboot to be forced.
• Unable to access LUNs/filesystem after storage failover and giveback from NetApp ONTAP
