HP StorageWorks External Storage XP user guide for the XP12000, XP10000, SVS200 (T1706-96009, October 2007)

• Interval
Interval of the CU:LDEV number for mapping each volume. When two or more LDEVs are created from
one external LU and mapped, the CU:LDEV number is set at intervals specified in each created LDEV.
For example, set the interval as follows:
•IntheDevice list, select three external LUs.
•InCreate LDEVs on the Auto Map Setting window, select 3 (nineLDEVsarecreated).
•InInterval, select 1.
• Set the starting CU:LDEV number to 00:00.
For this example, LDEVs created from the first external LU are mapped to 00:00, 00:02, and
00:04, respectively. The starting CU:LDEV number of LDEVs created from the second external
LU is 00:06, and subsequent LDEVS are mapped to 00:08 and 00:0A. The starting CU:LDEV
number of LDEVs created from the third external LU is 00:0C, and subsequent LDEVs are mapped
to 00:0E and 00:10.
• LDEV map
Each cell in the map represents an internal XP CU and LDEV number. Select a cell for the internal
LDEV on the map. The selected cell turns blue, and the LU of the selected cell becomes the first
CU:LDEV number of the mapped destination LUs. Defined (in use) internal LDEVs appear in gray, and
internal LDEVs to be mapped appear in white.
• Clear button
Releases the cell selected on the LDEV map.
• OK button
Closes the Select LDEV window, and returns to the Auto Map Setting window. On the Auto Map
Setting window, the CU:LDEV number you selected on the Select LDEV window as the head CU:LDEV
number of the mapped destination internal LDEVs appears in Start CU:LDEV.
• Cancel button
Cancels all settings in the Select LDEV window, and returns to the Auto Map Setting window.
To map multiple external LUs as internal LDEVs at one time:
1. Select the LU Operation tab. The LU Operation pane appears.
2. In the Device tree, select Discovery. WWNs identifying the external array port that can be connected
appear in the tree.
3. In the Device tree, select the port (WWN) you want to connect from the WWNs displayed. External
LUs that can be connected from the port (WWN) selected in the tree appear in the Device list.
4. In the Device list, select the external LUs you want to map as internal LDEVs, right-click, and select
Add LU (Auto). The Auto Map Setting window (Figure 48) appears.
5. Set the attributes for the external LUs you selected on the Device list.
NOTE:
Attributes for all LUs mapped at one time are identical.
• To select the first CU:LDEV number of the mapped destination internal LDEVs and the
mapping interval, go to step 6.
• To let External Storage XP select the first CU:LDEV number, go to step 9.
6. Click Select LDEV. The Select LDEV window appears.
7. Select the first CU:LDEV number of the mapped destination internal LDEVs and the mapping interval.
8. Click OK. The Auto Map Setting window appears.
