Before you configure redundant LU paths, make sure to read the information in Guidelines for managing LUs.
You might want to define redundant LU paths so that if one LU path fails, you will be able to switch to its redundant path.
To define redundant paths when LUN security is disabled, you must redefine the LU path.
To create a redundant 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 or an iSCSI target.
- Copy one or more (but not all) LU paths defined in a host group or an iSCSI target.
