HP XP External Storage Software - Manual (Page 91)

Displays the Select Paths pane ( Figure 43 ). Use the Select Paths pane to select paths as candidates
for primary and alternate paths and select paths that cannot be set to primary and alternate paths.
By default, all paths with a confirmed connection status of normal are set as candidates for primary
and alternate paths. However, to set a specific path as the alternate path, use the Select Paths
pane to specify candidates for alternate paths. Alternate paths are automatically set from the
candidates, as many as the number set in Alternate Path.
CAUTION:
If you do not set alternate paths on the Select Paths pane, alternate paths are automatically set
according to the WWN selected in the
Device tree on the LU Operation pane when you started
the Add LU operation.
• Clear button
Resets all the external LU's attributes.
• CU list
CU number of the local array to which you want to map the external LU. Select the CU number
from the list. When the Limited check box is selected, the selection range is limited to the CU
belonging to the SLPR displayed in CLPR.
• Linear button
Maps all external LUs listed in the CU:LDEV list at one time. When you click Linear and then select
an internal LDEV on the LDEV map, External Storage XP automatically selects from the LDEV map
the same number of internal LDEVs as external LUs listed in the CU:LDEV list, starting at the internal
LDEV you selected. The LDEV numbers of the selected internal LDEVs are sequential. When Interval
is set, mapping is done at the specified number of intervals. To map one external LU to another
internal LDEV after mapping the external LU automatically using the Linear button, release the
Linear button, and map the external LU individually.
• CU:LDEV list
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
