Select Paths Pane - HP StorageWorks XP12000 User Manual

Displays the XP12000/XP10000/SVS200 CU:LDEV numbers of external LUs mapped as internal
LDEVs. (N/A) (Not Assigned) means the external LUs are not yet mapped as internal LDEVs. To map an
external LU as an internal LDEV, select an external LU with (N/A) in the CU:LDEV list. To map all external
LUs in the CU:LDEV list at one time, use the Linear button.
• Interval
If you select two or more volumes in the CU:LDEV list or click Linear for mapping, you can select the
interval that arranges each volume. Values can be from 0 to 255. Default is 0.
For example, if you select three volumes in the CU:LEDV list, set Interval to 255, and map the first
volume to CU:LDEV number 00:01, the second and third volumes are mapped to 01:01 and 02:01,
respectively.
• LDEV map
Each cell in the map represents an internal LDEV. Select a cell for the internal LDEV on the map. The
selected cell turns blue, and the selected LDEV is mapped to the external LU. internal LDEVs that have
been mapped appear in gray, and those not yet mapped appear in white.
• Previous and Next buttons
If you select multiple external LUs in the Device list, click Previous to map the external LU in the row just
above the currently selected external LU. Click Next to map the external LU in the row just below the
currently selected external LU.
• OK button
Displays the SSID window, where you can continue with the next step of the mapping operation. If the
SSID setting is not necessary, the Add LU window closes, and the LU Operation pane appears.
The OK button is available when mapping on the Add LU window is complete.
• Cancel button
Cancels all mapping operations, closes the Add LU window, and returns to the LU Operation pane.

Select Paths pane

All paths that can be set as primary and alternate paths appear in the Select Paths pane. To set a specific
path as the alternate path, use the Select Paths pane to specify candidates for the alternate paths.
If you let alternate paths be automatically set with all connected normal paths as candidates, you can omit
the setting operation on the Select Paths pane.

• Port
Local array ports. You can set alternate paths for the selected port.
• Selected Paths
External array port for which you can set the alternate path connecting to the local array port selected
in the Port list. By default, all ports that can be set as alternate paths appear. The WWN identifying the
external array port appears. If the primary path and as many alternate paths as you set in Alternate
Path in the Add LU pane cannot be set with the paths selected in Selected Paths, an error occurs and
appears in the Preset list.
