Map a LUN to the igroup containing the NPIV WWPNs.

Configure a matching NPIV port on the NetApp controller.

Set options.npiv.enable to TRUE on the NetApp controller.

Create a zone containing NetApp target ports and NPIV WWPNs.

Create an igroup on the NetApp controller containing the NPIV WWPNs.

I/O will fail over to any port on the original controller but NOT on the partner controller that is part of the associated portset. Choice of path will be controlled by the host's MPIO weighting table.

I/O will fail over to any port on either controller that is part of the associated portset. Choice of path will be controlled by the host's MPIO weighting table.

I/O will fail over to any port on the original controller that is part of the associated portset. Choice of path will be controlled by NetApp storage system igroup settings.

I/O will fail over to any port on either controller that is part of the associated portset. Choice of path will be controlled by NetApp storage system igroup settings.

The LUNs offset, size of the prefix and suffix is determined by the LUN type, which differs for different operating systems.

The LUN types are merely for administrative ease of use and the LUN types can be changed on the fly after creation.

The LUN types allow the appropriate host operating systems to use the LUN. For example, a VMware type LUN cannot be read from /written to using a Solaris host.

The host operating system will panic when the "wrong" LUN type is selected on the NetApp storage system.

Dual power supplies should be placed in all equipment.

Dual power feeds should be run to all equipment.

Power feeds should be connected to the closest available outlet inside the cabinet.

Power feeds should be connected to separate circuits on the same data center PDU.

Power feeds should be connected to separate outlets connected to two separate PDUs.

to assign a specific percentage of the queue resources on each physical port to the igroup

to manage pathing to the LUNs

to reserve a minimum percentage of queue resources for a specific igroup

to limit the number of concurrent I/O requests an initiator can send to the storage system

to restrict an igroup to a maximum percentage of use

to manage space reclamation

The same LUN is present in two igroups with differing ALUA states.

The starting offset of the first file system block on the host.

The LUN is a boot LUN.

The LUN is part of a logical volume.

cascade

partial mesh

There more paths to LUNs.

Target port WWPNs will change on at least one controller.

You must use hard zoning (zoning by ports).

There are fewer paths to LUNs.
