7-6-4 Modifying LUN Security for a Group
The system administrator, local system administrator, storage administrator, and local storage administrator
can modify the LUN security of the LUN(s) in a storage group. Guest and local guest users do not have access
to this function.
When you add a host WWN to a LUN, you secure that LUN to that WWN. When you remove a host WWN from
a LUN, you unsecure that LUN from that WWN. For the StorageWorks XP12000/XP10000 and
XP1024/XP128, a secured group (that is, a logical group containing secured LUNs) constitutes one host group
(host storage domain) on a port of the specified storage subsystem. When you reach the maximum number of
host groups on a port, you must use another port for securing storage. The StorageWorks XP12000 supports a
maximum of 255 host groups per port, and 57,344 host groups for the entire storage subsystem. The
StorageWorks XP10000 support a maximum of 255 host groups per port, and 12,240 host groups for the entire
storage subsystem. The StorageWorks XP1024/XP128 supports a maximum of 128 host groups per port and
8,192 host groups for the entire storage subsystem.
NOTE: For StorageWorks XP12000/XP10000 and XP1024/XP128, the LUN Manager feature must be
enabled. For the StorageWorks XP512/XP48, the Secure Manager feature must be enabled.
To modify the LUN security of one or more LUN(s):
1. Log in to Device Manager as a system administrator, storage administrator, local system administrator, or
local storage administrator.
2. Select the Logical Groups object in the navigation frame, expand the tree as needed (click on + ), and
then select the storage group for which you want to modify LUN security (refer to Figure 7-8 ).
3. In the information frame, select the desired LUN(s), and then select the Modify Security button to start the
Modify Security wizard.
4. Select Hosts Step. The Select Hosts panel (see Figure 7-25 ) displays the hosts whose security can be
set. Checkboxes are pre-selected on the hosts that have already been granted access permissions for
the selected LUN. Select the checkboxes for the hosts that you want to grant access permissions for the
LUN. If you clear a checkbox, access permissions to the LUN for that host are revoked. After you select
the hosts to grant access permissions, click on Next to go to the next step.
5. Select WWNs Step. The Select WWNs panel (see Figure 7-26 ) displays the WWN(s) for the selected
host(s) and allows you to select the WWN(s) that you want to secure to the LUN(s). After selecting the
desired WWN(s), select Next to continue.
The security property that can be set depends on the selected paths and the status of the WWNs.
a. If the selected WWNs are not assigned to all of the selected paths, the security properties that can be
set are as follows:
