map volume
Description
Maps specified volumes using settings that override the volumes’ default mapping.
When a volume is created, if no mapping settings are specified the volume is not mapped. Otherwise,
those settings become its default mapping, which specifies the controller host ports and access level
that all connected initiators have to the volume, and the LUN presented to all initiators to identify the
volume. The default mapping’s LUN is known as the volume’s default LUN.
The map volume command creates mappings with different settings for different initiators.
Optionally, you can specify the LUN, ports, and access level for a mapping. A mapping can make
a volume accessible to initiators, or inaccessible to initiators (known as masking). For example,
assume a volume’s default mapping allows read-only access using LUN 5. You can give one initiator
read-write access using LUN 6, and you can give a second initiator no access to the volume.
