3. In the Volume LUN Mapping section, assign a logical unit number (LUN) for each port that the volume will
be accessed through. Check the Use same LUN for all ports of the same type check box to have all
Fibre Channel, SAS-to-Host, 10GbE, or iSCSI ports use the same LUN mapping.
4. Set the Default Access (applied to new or unknown hosts) by selecting Deny , Read , or R/W :
Select Deny to prevent all new or unknown hosts from accessing the volume. This is the default

If Use Default is unchecked, this setting overrides the Default Access setting. You can select Deny ,
Read , or R/W as the default for all host groups.

If Use Default is checked, the host or host group will use the Group Default setting (if the host is part
of a group) or the Default Access setting (if the host is not part of a group). This is the default setting.
If Use Default is unchecked, this setting overrides the Group Default and Default Access settings.
Select Deny , Read , or R/W to set the access privileges for the specific host.
