Appendix C Performing Advanced Diagnostics
The xStack Storage Array provides two menus for performing advanced diagnostics, one that
can be accessed through the serial port and another that can be accessed through the
management port.
The serial port diagnostic menu is accessed during startup. This menu lets you reset all
admin passwords, download configuration parameters, access the Enclosure Services Test
Tool, or continue with the boot operation. For more information, see Section C.1.
The management port diagnostic menu is used if the xStack Storage Array is operational, but
the management console is not available. This menu lets you reset the xStack Storage Array
to factory defaults, reboot or shut down the xStack Storage Array, and change the out-of-
band port configuration. To access this menu, you must know the login username and
password. For more information, see Section C.2.
