[INS-40718] Single Client Access Name (SCAN): could not be resolved. ( LDOMS & Zones)

Cause

The name you provided as the SCAN could not be resolved using TCP/IP host name lookup. Action-Provide name to use for the SCAN for which the domain can be resolved

Global Zone :
=============

# svccfg
svc:> select name-service/switch
svc:/system/name-service/switch> setprop config/host = astring: "files dns"
svc:/system/name-service/switch> select system/name-service/switch:default
svc:/system/name-service/switch:default> refresh
svc:/system/name-service/switch:default> validate
svc:/system/name-service/switch:default> exit

# svcadm refresh name-service/switch

# svcadm restart /system/name-service-cache;

then, I can resolve host using telnet/ping.
