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.
