Setting alternate paths for external LUs
Before using an external LU mapped as an internal LDEV, you must set at least one alternate path
from the internal LDEV to the external LU (likely by way of an alternate controller). The number of
alternate paths set is the same as the number specified on the Add LU or Auto Map Setting window
when the LU was mapped as the internal LDEV. For more information, see
Use the Path Setting window (
) to add and define alternate paths to the paths
set at mapping or change the alternate paths.
NOTE:
You can add or delete alternate paths by selecting multiple external LUs at one time. For
more information, see
Adding alternate paths by selecting multiple external LUs (Add Paths)
and
Deleting alternate paths by selecting multiple external LUs (Delete Paths)
CAUTION:
You cannot delete all the current alternate paths to substitute newly-added alternate
paths for them in one operation. To replace all the current alternate paths with newly-added alternate
paths, you need to perform more than two operations and leave at least one current alternate path
setting when you perform the first operation.
Use the Path Setting window (
) to define alternate paths.
You can perform the following operations on the Path Setting window:
•
•
Changing a defined alternate path priority
