Mapping volumes to an ESXi server
23 Dell EMC SC Series: Best Practices with VMware vSphere | 2060-M-BP-V
Multipathing to an ESXi host is automatic when the server object has more than one HBA or iSCSI initiator
ports assigned to it. In other words, the advanced options must be used if the server does not need a volume
multipathed.
Advanced server mapping options
Advanced mapping options for an ESXi host
Function
Description
Select LUN
Clear the Use next available LUN option to manually specify the LUN. If
this box is not checked, the system automatically assigns the next
available LUN.
Restrict Mapping Paths
Use this option when a volume only needs to be mapped to a specific
HBA in the ESXi host.
Configure Multipathing
This option designates how many of the SC Series front-end ports
allowed for the volume to be mapped through. For example, if each
controller has four front-end ports, selecting unlimited maps the volume
through all four. Selecting two only uses two of the four front-end ports.
The system automatically selects the two front-end ports with the fewest
mappings.
Configure Volume Use
VMFS does not recognize read-only mappings, so this option should not
be used.
