The system configuration interface provides configuration settings and options that can
be used with the system.
These settings and options can have the following scope:
- System
- Logical unit (LU)
- The system attempts to
follow preferred ownership that is specified by the system. You can specify which controller (A or
B) is used to perform I/O operations to a particular LU. If the system can see the
ports of the preferred controller and no error conditions exist, it can
access that LU through
one of the ports on that controller. Under error conditions, the ownership is ignored.
- You must enable the following options on any LUs that are mapped to the system:
- read caching
- write caching
- write cache mirroring
- You must not have caching without batteries that are enabled.
