Preset list.

CLPR (see
External LU attributes set by mapping
)
When cache memory is partitioned using XP Disk/Cache Partition, you can select the CLPR used
to access the mapped LU from the list. The SLPR number that the selected CLPR belongs to appears
on the right of the list. However, when you select a mainframe emulation type in Emulation Type,
you can only select CLPRs belonging to SLPR number 0. The Limited check box appears on the
right of the SLPR number. To display only CUs defined for the selected SLPR, select the Limited
check box. To display all CUs, regardless of the SLPR, clear the check box. By default, the Limited
check box is selected.
•
Select LDEV button
Displays the Select LDEV window (
) where you can select the first CU:LDEV number in
the series.
•
Select Paths button
Displays the Select Paths pane (
). Use the Select Paths pane to select paths as candidates
for primary and alternate paths and select paths not 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, specify candidates for
alternate paths on the Select Paths pane. Alternate paths are automatically set from the candidates,
as many as the number set in Alternate Path.
See
Mapping external LUs individually (Add LU)
for more information about settings on the Select
Paths pane.
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 start the
Add LU operation.
•
OK button
Starts mapping internal CU:LDEV numbers to external LUs. When mapping is complete, the SSID
window appears if the SSID setting is required. If the SSID setting is not required, the Auto Map
Setting window closes, and the LU Operation pane appears.
•
Cancel button
Cancels all mapping operations, closes the Auto Map Setting window, and returns to the LU
Operation pane.
