Procedure
1.
In the web interface system tree, click the logical unit node.
2.
Click
Access
on the Logical Unit Overview pane to start the Access Policy wizard. The first step of
the access policy wizard provides an overview of the process.
3.
After you read the overview, click
Next
to continue to the Modify Access Policies pane.
4.
The tree titled
Available
shows a tree of all controller ports in the system with each port’s available
access policies underneath. The tree titled
Assigned
shows the policies currently in use for each port
in the system. If there are potential conflicts between policies that are assigned and policies that are
available, the conflicting available policies are disabled in the
Available
tree. If the system detects a
host server that is connected to the controller port for the access policy, the policy node’s connector
icon includes a plus sign.
a.
To add an Access Policy, select the wanted policy node from the
Available
tree. When it is
highlighted, the
>>
button becomes enabled. Clicking this button moves the policy from the
Available
tree to the
Assigned
tree. When a new policy is added to the
Assigned
tree, its text
color is green.
b.
To remove an Access Policy, select the wanted policy node from the
Assigned
tree and click the
<<
button. The policy is removed from the
Assigned
tree and added to the
Available
tree. When
an in-use policy is deleted from the
Assigned
tree, its text color is red in the
Available
tree. Policy
changes are not committed until the next step in the wizard.
5.
When you finish making policy changes, click
Next
to continue to the modifications review page.
6.
If policy modifications are only policy additions, click the
Confirm
check box and click
Finish
to exit
the wizard and commit the policy changes. If there are policy removals, you are required to enter the
admin login password to finish the wizard.
Logical unit masking
The logical unit (LU) masking feature assigns access policies to a LU on the storage system, thus
restricting access to specific host servers through a controller port.
About this task
This feature is opposed to
Open Access
where the LU is accessible to all hosts connected to the port.
When the LU masking feature is installed, access to specific hosts can be created through the web
management interface’s Access Policy wizard. With LU masking available, the wizard shows the
worldwide port names (WWPNs) of connected hosts in its
Available
policy tree. The wizard also
supports the ability to create host ID aliases. You can use a host ID alias to associate a meaningful text
name with a host’s WWPN.
Procedure
1.
In the web interface, select the logical unit in the system tree.
2.
To run the Access Policy wizard, click the
Access
button on the
Logical Unit Overview
screen.
3.
To create an alias, click the
New Alias
button underneath the
Available
policy tree. This action opens
a dialog where you can enter the host’s WWPN in the
Host ID
text box and the alias name in the
Alias
text box.
4.
Click
Add
to finish and save the alias. The aliased host is listed in the Access Policies tree for each
controller.
5.
To remove or edit existing aliases, use the
Edit Alias
button on the Access Policy wizard.
6.
The
Remove
button deletes the currently selected alias. To change an alias’ name, select the alias in
the table and click the
Re-alias
button to enable the
Alias
table cell for editing. When changes are
complete, press the
Enter
key to leave edit mode and save the changes to the table. Click
OK
to exit
the dialog.
