Description
No image (flash partition empty).
Initial state of the flash partition if no image is downloaded. The
partition also enters this state when the image download fails because
of a CRC error.
Allowed state transitions from SSU_EMPTY:
Inactive flash image.
Image state after a successful download from a remote repository. An
image also reverts to this state after explicit canceling of one-shot test
mode or after system reboot if an image running in one-shot test was
not validated.
Allowed state transitions from SSU_INACTIVE:
Inactive flash image marked for one-shot test.
An inactive image can be marked for one-shot test using SSU IPMI
command. Marking for one-shot test does not imply automatic system
reboot.
Possible state transitions from SSU_ONESHOT:
Flash image running in one-shot test mode.
State entered by one-shot test image after system reboot. The
running one-shot image must be explicitly validated using IPMI.
Otherwise, it automatically reverts to inactive state after next reboot.
Possible state transitions from SSU_ONESHOT_RUNNING:
Active flash image.
A validated image stored in flash, but not currently running. An active
flash image should not be running when a remote image is loaded
(SSU_REMOTE_RUNNING) or if the second image is tested in one-shot
mode (SSU_ONESHOT_RUNNING). The only way to leave this state is
to validate the second image. The active image cannot be overridden,
nor marked for one-shot mode.
Possible state transitions from SSU_ACTIVE:
• action = successful download of a new image
• action = mark image for one-shot test mode
• action = failed attempt to download new image
• action = successful download of a new image
• action = cancel one-shot test mode using IPMI
• action = successful reboot (new image works)
• action = failed reboot (watchdog expires)
• action = validate current configuration
• action = cancel one-shot test mode using IPMI
• action = reboot without prior validation
• action = validate the other image
