Removing Standard
Mapping
Before you can assign a LUN
filter, you have to remove the standard host mapping (indicated by M
labels [Mapped] )
from the array. Standard mapping enables all hosts to see all standard
mapped logical drives. LUN filtering restricts the mapping to specific
host(s).
- From the main window,
click the Filter View tab.
- From the right pane, click
each All Hosts item, and drag and drop it to Storage Pools.
Click Yes to the
warning message.
A confirmation message
is displayed.
- Click Close.
When you return to the
filter tab, note that the M label ( )
has been removed from the logical drive.
Assigning
a LUN Filter
After you remove the standard
mapping, you are ready to assign a LUN filter by mapping logical drives
to hosts.
- Select a logical drive
under Storage Pools, and drag and drop it to the appropriate HBA device
under Hosts.
A warning message is displayed.
If the HBA device connected
to the array is not known, drag and drop the logical drive to the
host (server). The program prompts you to filter the array for each
HBA device in the host. When this happens, the logical drive is visible
to the HBA device on the host, but it is not visible (or accessible)
to any other HBA device.
- Click Yes.
The Specify Map Information
window is displayed. Note that Sun StorEdge Configuration Service
automatically maps the logical drive to the first HBA device listed
in the host if there is more than one HBA device.
- Assign the logical drive
to a primary or secondary controller and with the desired channels
and LUN ID numbers, and then click OK.
A confirmation message
is displayed.
- Click Close.
The assignment of the
primary controller or secondary controller to an HBA device is selected
for the initial LUN filter assignment, and cannot be changed unless
you delete the LUN filter assignment and start over.
To apply a LUN filter
to a second host for one array, repeat Step 6 under Adding HBA
Devices Manually.
A warning prompt is displayed
informing you that two users accessing the same logical drive at
the same time might cause data corruption. This is a characteristic
of some host OSs. Click OK to add the additional host.
An F (Filtered)
( )
label indicates that a LUN filter has been applied to the host.
Deleting a
LUN Filter
- From the main window,
click the Filter View tab.
- From the right pane, select
the associated WWN, and drag and drop it to Storage Pools.
A warning message is
displays.
- Click Yes.
A confirmation message
is displayed.
