COMPAQ StorageWorks Upgrading From an HSZ70 to an HSG80 Array Controller
Page 26 EK-HSG80-UP. B01
Appendix B
This appendix describes a procedure that can be used to restore an HSG80 controller to its
factory default state. If the HSG80 controller has been previously used in a subsystem it should
be restored to its initial configuration or erased before it is used in the HSZ70 to HSG80 upgrade.
Otherwise, the saved configuration will not be restored.
CAUTION
This procedure may result in the loss of both customer data
and subsystem configuration data. Therefore, the following
procedure should NOT be performed on a subsystem which
contains valid customer data or a valid subsystem
configuration.
To erase an HSG80 controller perform the following steps:
NOTE
Only one HSG80 controller and one HSG80 cache module
can be installed in the subsystem at a time.
1. Power off the entire storage subsystem.
2. Install one HSG80 controller, one cache module.
3. Connect the External Cache Battery (ECB) cable to the HSG80 cache module.
4. Using a small screwdriver, press in and hold the # 5 OCP button.
5. Holding the #5 OCP button, turn on the subsystem cabinet power.
6. Continue to hold the #5 OCP button until the green
RESET button begins to flash at 1 Hertz.
7. Release the #5 OCP button and let the controller continue to boot.
8. The controller will boot and then halt with OCP lights 1 and 2 and 3
ON.
9. This controller and cache have been restored to a factory default state.
10. Remove the HSG80 controller and cache module.
11. If necessary, repeat the process for the other HSG80 controller and cache module.
