Determining, setting, or changing the external LU cache mode
You set the cache mode when you define external LUs. HP strongly recommends that you set cache
mode to Disabled for external LUs. For instructions on mapping external LUs in a new configuration,
see Mapping external LUs (Add LU) .
CAUTION:
Before you delete any LUs that you want to remap, carefully record necessary configuration information.
If you remap existing LUs with changed configuration settings (other than cache mode), you can lose
access to the LUs and the data they contain.
Determining if the cache mode is disabled
If you have an existing configuration and need to determine if your external LUs are configured with
cache mode disabled, follow this procedure:
1. In the XP Remote Web Console main pane, click the External Storage button in the left pane. The LU
Operation pane appears.
2. In the Device tree, select an external device group.
3. In the Device list, check the Cache Mode setting ( Figure 19 ). If cache mode is enabled, you should
change it to Disabled.

Changing the cache mode
If you need to change the cache mode for existing external LUs, you must delete and remap the external
LU path and definition.
