Setting alternate paths on each external LU
Before you can use the external LU mapped as an internal XP LDEV, set at least one alternate path from the
internal XP LDEV to the external LU (likely by way of an alternate controller). For detailed information, see
” Alternate paths ” on page 12.
NOTE: You can add or delete alternate paths by selecting multiple external LUs at one time. For more
information, see ” Adding alternate paths to multiple external LUs ” on page 61 and ” Deleting alternate
paths of multiple external LUs ” on page 63.
CAUTION: If the number of alternate paths specified is out of range (for example, too few), an error is
displayed in the Preset list.
Use the Path Setting window to define alternate paths.

• ” Canceling defined alternate paths ” on page 61
• ” Changing alternate paths ” on page 61
The Path Setting window displays information about external disk arrays and condition of paths set from
