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 Start-
Of-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,
