Once the SPs have completed reboot, a login prompt is displayed. Login using the "service" user account and password. Verify the basic state of each SP by running the following:

spb:~> svc_diag                 # Verify the basic state of each SP
spb:~> svc_check_hw_config -d   # Check the DIMM configuration.

If determined that the Unity system appears to be OK, except for being in Service Mode (e.g., no visible Fault LEDs or Hardware failures), you may attempt to clear the boot counters, and reboot each SP using the following sequence on each SP

spb:~> svc_rescue_state -l      # Lists the current boot counter numbers
spb:~> svc_rescue_state -c      # Clears the boot counters to zero
spb:~> svc_shutdown -r          # Reboots the SP from where you are running the command
