To create an alternate LU path, copy the original LU path from one port to another. For example,
if you want to define an alternate for the LU path from the CL1-A port to logical volume 00:00:01,
copy the LU path from the CL1-A port to another port.
Use one of these methods to copy LU paths:
•
Copy all the LU paths defined in a host group
•
Copy one or more (but not all) LU paths defined in a host group
Before taking the following steps:
•
See
“LUN Manager rules, restrictions, and guidelines” (page 166)
for important information.
•
To define alternate paths when LUN security is disabled, you must redefine the LU path.
