3. Select a volume.
The Current Host-Volume Relationships panel shows which host nodes have access
to the selected volume. For the selected volume you might see the following
mappings:
■ All Hosts – Shows the settings used by all host nodes to access the volume. This
entry is displayed only if no host nodes are explicitly mapped. If a host node is
explicitly mapped, All Hosts changes to All Other Hosts.
■ IQN-value – Shows an explicit mapping between a host node and the volume.
■ All Other Hosts – Shows the access settings used by all host nodes except by
explicitly mapped host nodes. This entry is displayed only if host nodes are
explicitly mapped. If no host nodes are explicitly mapped, All Other Hosts
changes to All Hosts.
For each host entry, the IQN and nickname, LUN, and target-port access privileges
are shown. The access privilege for a target port can be read-write, read-only, or
none (no access; masked).
4. To change the default mapping for the selected volume:
a. In the Assign Host Access Privileges panel, select All Other Hosts.
b. To set read-write or read-only access on one or more ports, specify a LUN and
select port access privileges. More than one host node can use the same LUN to
access the same volume. A mapping cannot include both read-write and read-
only access.
c. Click Map It.
When processing is complete, the page shows the mapping changes.
5. To add or change an explicit mapping for the selected volume:
a. In the Assign Host Access Privileges panel, select a host node.
b. To set read-write or read-only access on one or more ports, specify a LUN and
select port access privileges. More than one host node can use the same LUN to
access the same volume. A mapping cannot include both read-write and read-
only access.
c. Click Map It.
When processing is complete, the page shows the mapping changes.
