sense data indicating that a power-on or reset has occurred. The Sense Key, ASC, and ASCQ will be 0x06, 0x29, and 0x00 respectively. 8. Mode Select Commands disabled: The controller will now disable Mode Select Commands until the Start-Of-Day process is complete. This is required so that subsystem configuration changes are prohibited until the controller has finished booting. Mode Select commands issued by a host during this time period, will be returned with an error by the controller, indicating that the addressed logical unit is currently not ready, and is in the process of becoming ready. 9. Host Side selection enabled: The controller will now enable selection on the host side, allowing host to select the controller. On a bus reset, this step is completed within 250ms of receiving the bus reset. On power-up, this step is completed within 10 seconds. 10. Respond to host's Inquiry commands: The controller is now able to respond to host Inquiry commands, based on the knowledge of previously-existing logical units, as well as their ownership information. An Inquiry issued by a host to a logical unit, will return information indicating whether the logical unit exists, and if it is owned by this controller. If the controller receives a non-Inquiry command, it delays the command a period of time determined by the value set in NVSRAM, before returning a "Not Ready - logical unit is in process of coming ready" error. 11. Drive operations initialized: The controller will now initialize firmware components to handle drive operations, allowing the controller to issue commands to the drives. 12. LUN ownership read: The controller will read LUN ownership from the NVSRAM. 13. Loaded firmware modules displayed: The controller will display a list of loaded firmware modules on the serial port. 14. Spin up of drives: The controller reads NVSRAM information for previously existing drives, and spins up the drives, following the Drive Spin-up algorithm as defined in NVSRAM. If the Drive-Spin-up algorithm defined in the NVSRAM, requires the controller to wait for a Start-Unit command from the host before spinning up the drives, the StartOf-Day process will be suspended at this time, until the host issues a Start Unit command. 15. Read drive and LUN configuration information from dacStore. The controller will now read the drive and LUN configuration information from the dacStore on the drives, 224 Controller Enclosure Troubleshooting
