Figure 23 LDEV Information pane
Deleting and remapping the external LU
You must delete and remap each LU that needs the cache setting changed. Using the information
recorded in
Collecting device information , delete and remap each LDEV.
1. On the LU Operation pane, select the appropriate external LU group number in the Device tree.
2. In the Device list, right-click the external LU that you want to delete, and select Delete LU ( Figure 21 ).
3. Click Apply.
4. Click either Yes or No. If you click Yes, skip the next step.
5. Click OK in response to the warning message.
6. Click OK.
7. Remap the LU using all the previous settings except for the cache mode setting, which is disabled.
See
Mapping external LUs (Add LU) .
NOTE:
When scanning for devices to add, the order in which devices are discovered might be
different. The UUID is always the same for the same external device. Ensure that the UUID
of the device being remapped matches the UUID that was deleted for the same LU number.
8. Recheck to ensure that the same external storage LUs (identified by UUIDs) are now assigned
their original settings and the desired cache mode. If not, delete and remap the external LU again.
