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

Alternate paths

.

Use the Path Setting window (

Figure 51

) 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. For the detailed procedure, see section 5.5.5.

Use the Path Setting window (

Figure 51

) to define alternate paths.

You can perform the following operations on the Path Setting window:

Defining alternate paths
Changing a defined alternate path priority
Canceling alternate path definitions
Changing alternate paths

5.5.5 Replacing all the alternate paths with newly-added alternate paths.

The Path Setting window displays information about external arrays and the condition of paths set from

the internal LDEV to the external LU.
