Figure 4: Connecting PC and terminal cables to the controller
maintenance port (dual-redundant configuration shown)
2. From the host console, halt all host activity to the
controller, and dismount the logical units in the subsystem.
3. If you are using Microsoft
2000, shut down the server.
4. Run the Fault Management Utility (FMU) to obtain the last
failure codes, if necessary.
5. Determine whether the disk was initialized with the
SAVE_CONFIGURATION switch, and then perform one of
the following options:
If the disk was not initialized with the
SAVE_CONFIGURATION switch, locate existing
