Note
: If you delete numerous paths at one time, the deletion may take time and the dialog box may
seem to hang temporarily.
Defining and Viewing Alternate Paths
LUN Manager enables you to define alternate paths. If one LU path fails, you can switch to its alternate
path.
To create an alternate path, you need to copy the original path from one port to another. For example, if
you want to define an alternative for the LU path from the CL1-A port to the logical volume 00:00 :01,
you need to copy the LU path from the CL1-A port to another port.
Copying Paths between Fibre Channel Ports
To use alternate paths, you must copy LU paths from one port to another.
Caution
: Before taking the following steps, see “
” on page 19 for
important information.
Caution
: To define alternate paths when LUN security is disabled, you must redefine the LU path.
To define alternate paths:
