Managing multipathing configuration of a VMFS datastore
Storage LUNs presented to the ESXi hosts preferably need to be made highly available. This is achieved by enabling multiple connectivity paths between the ESXi hosts and the SAN storage. Once configured correctly, these paths can then be used either to failover or load balance the I/O activity.
In this section, we will learn how to view the current multipathing configuration for a particular LUN.

- Select the desired datastore, navigate

|Connectivity and Multipathing
, select any of the ESXi hosts that the datastore is currently mounted to, to view its multipathing configuration. In this case, the LUN presented from an iSCSI storage array has only a single path which is not an ideal configuration in a production...
