Managing LU paths
You can modify the LU paths configuration with LUN Manager when the system is in operation,
but not when host I/O is in progress. Managing LU paths includes the following tasks:
•
“Deleting LU paths” (page 181)
•
“Clearing a UUID setting” (page 181)
•
“Viewing LU path settings” (page 182)
Deleting LU paths
The Storage Administrator (Provisioning) role is required to perform this task.
CAUTION: Do not delete LU paths when host I/O is in progress.
1. In the Remote Web Console main window, in the Storage Systems tree, select LDEVs using
either of the following methods.
•
Select Logical Devices, and then select the LDEVs tab.
•
Select Pools, select a pool, and then select the Virtual Volumes tab.
Or, select logical units using the following method.
•
Select Ports/Host Groups, select a port, select a host group, and then select the LUNs
tab.
CAUTION: When an LDEV is selected and Delete LUN Paths is performed, all LUN paths of
the selected LDEV are deleted by default.
2. Click More Actions and select Delete LUN Paths.
3. In the Delete LUN Paths window, confirm that the LU paths that you want to delete are listed
in Selected LUN Paths.
If LU paths that you do not want to delete are listed, select the LU path you do not want to
delete, and then click Remove from Delete process.
4. If necessary, check the Delete all defined LUN paths to above LDEVs check box. When checked,
all additional LU paths on the selected LDEVs will be deleted.
5. Click Finish to open the Confirm window.
If you want to start shredding operations to delete the data of the volume, click Next. For
detailed information about shredding operations, see the HP XP7 Volume Shredder for Open
and Mainframe Systems User Guide.
6. In the Confirm window, confirm the settings, in Task Name type a unique name for this task
or accept the default, and then click Apply.
If Go to tasks window for status is checked, the Tasks window opens.
If you delete many paths at one time, the deletion process may take time and the dialog box may
seem to hang temporarily.
Clearing a UUID setting
The Storage Administrator (Provisioning) role is required to perform this task.
You can clear the UUID setting that has been set to identify a logical volume from the host.
1.
In the Remote Web Console main window, in the Storage Systems tree, click Logical Devices,
and then select the LDEVs tab.
2. Select the LDEVs for which you want to clear the UUID setting.
3. Select Delete UUIDs. The Delete UUIDs window opens.
