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.

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.

Collecting device information

Before you remap an external storage device, collect the following information for each device:

• LU number in the group

• Universal Unique ID (UUID)

• Path settings

• CVS settings

• Mapped location

• External group number

• CU:LDEV identifier

To collect each of these items:

1. In the XP Remote Web Console main pane, click the External Storage button in the left pane. The

LU Operation pane appears.
