In the VLS, LUN masking occurs automatically for all hosts when you enable LUN mapping using the
global enable/disable LUN mapping setting. See
LUN Masking (v2.x)
By default all hosts on the SAN can access all the virtual libraries on the VLS. You can restrict a host's
access to the virtual libraries and/or tape drives (virtual devices) on the VLS by performing LUN
masking.
LUN masking should also be used when there are more virtual devices (LUNs) port mapped to a FC
host port than the operating system LUN restrictions support. This prevents the host's operating system
from seeing the virtual devices it needs to see on the port. For example, if a host's operating system
is configured to only see up to eight LUNs per FC host port, the host will not be able to see the virtual
devices numbered LUN8, LUN9, ..., and up. LUN masking limits the virtual devices (LUNs) the host's
operating system can see on the port, so that only the virtual devices the host needs to see are visible.
To perform LUN masking, from Command View VLS:
1.
Click the System tab.
2.
Select Chassis in the navigation tree.
3.
Click Host LUN Mapping Mode in the task bar.
The Host LUN Mapping Mode window opens and displays a list of the host world wide port
numbers (WWPNs) seen by the VLS FC host ports on the SAN

.
4.
Select Mapping Enabled in the Mapping Status box for each host for which you want to perform
LUN masking.
The hosts with mapping enabled are not able to access any of the virtual devices on the VLS until
you give them access by performing
5.
To assign a host name alias to a host WWPN listed, enter the host name in the Hostname box.
6.
To add a host WWPN to the list that is not plugged into the SAN yet, enter the host WWPN
number and then click Add.
7.
When you are finished making changes, click Apply Settings.
