Procedure 1. Before replacing the chassis, it is beneficial to run the following commands and save the output on the Data Domain system that is to be replaced. Use this information to verify that the procedure has completed successfully: # storage show all # disk show state # disk show hardware # system show ports # disk multipath status # filesys show space # enclosure show topology # vtl show config # vtl group show all # enclosure show power supply Field Replaceable Units DD6800 and DD9300 chassis 59 Page 64 of 80

Note l When you run these commands before and after the chassis replacement, the output should be the same. Save this information in case any configuration problems are found after the procedure has completed. l See the Data Domain Operating System Command Reference Guide for detailed information about these commands. Chassis replacement procedure Note l Only trained and qualified service engineer should be allowed to install or replace this equipment. l Before removing the chassis, label all cables attached to the chassis so that the cables can be reconnected correctly after the chassis replacement. l During the procedure, wear a grounding wrist strap to avoid ESD damage to the equipment. Data Domain recommends putting the current chassis and the new chassis on an ESD- free work surface that is large enough for the new and old systems to be side-by-side on a table or counter top to ensure the correct placement of all components in the new chassis. CAUTION If it is necessary to replace both the chassis and the SP module, do not replace at the same time. Important configuration information can be lost. In this instance, you must do a serial swap in which the SP module is replaced first, the system is booted, the system is brought down, and then the chassis is replaced. Shut down and disconnect the system Procedure 1. Stop the system using the system poweroff command to allow the proper shut down of the file system and other system components. Note The system poweroff command completes when the front panel blue LED turns off. For help connecting to a system using a laptop computer and terminal emulator, see the document FE Toolkit Inventory and Common Procedures for FRU Tasks at . 2. Label each of the cables as to their connection location. Taking a photograph for reference is also helpful for re-connecting the cables. 3. Disengage the wire clips, then disconnect both AC power cords from the rear of the system. Field Replaceable Units 60 Data Domain DD6300, DD6800, and DD9300 Field Replacement Unit Guide Page 65 of 80

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
