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 ” on page 22.
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) ” on page 91 and
” Deleting alternate paths by selecting multiple external LUs (Delete Paths) ” on page 93.
Use the Path Setting window ( Figure 51 ) to define alternate paths.
You can perform the following operations on the Path Setting window:
