When booting an Oracle Solaris system with the retained memory pseudo-device (for example, when the system is attempting to recover from a failed boot pool). The boot archive on the target boot environment might be out of sync. The boot archive SMF service will automatically rebuild the archive, then reboot. Instead of rebooting from the boot pool, the system erroneously attempts to reboot from the (now-nonexistent) retained memory device. This situation causes the reboot to fail, and the user is dropped to the ok prompt.
In order for this condition to occur, two situations are required:
The boot archive on the target boot environment is out of sync.
The system is booting with a boot archive stored in retained memory as a result of booting from the fallback image stored on the SP (OpenBoot boot alias 'fallback-miniroot').
If this condition occurs, you will see this error:
