What does Selective LUN Mapping (SLM) do?

The correct answer is C. It makes a LUN accessible only through paths on the node owning the LUN and its HA partner. Selective LUN Map (SLM) reduces the number of paths from the host to the LUN. With SLM, when a new LUN map is created, the LUN is accessible only through paths on the node owning the LUN and its HA partner. SLM enables management of a single igroup per host and also supports…

Explanation

Selective LUN Map (SLM) reduces the number of paths from the host to the LUN. With SLM, when a new LUN map is created, the LUN is accessible only through paths on the node owning the LUN and its HA partner. SLM enables management of a single igroup per host and also supports nondisruptive LUN move operations that do not require portset manipulation or LUN remapping. Portsets can be used with SLM just as in previous versions of Data ONTAP to further restrict access of certain targets to certain initiators . When using SLM with portsets, LUNs will be accessible on the set of LIFs in the portset on the node that owns the LUN and on that node's HA https://library.netapp.com/ecmdocs/ECMP1636035/html/GUID-62ABF745-6017-40B0-9D65- CE9F7FF66AB3.html
