Shutdown upgrade procedure for dual-redundant and single-controller
configurations
This upgrade procedure applies to dual-redundant controller configurations and
single-controller configurations. Specific controllers are referred to as
controller A or controller B during the procedure. For clarity, the CLI prompts
illustrated in this procedure use HSGA> and HSGB> to indicate which controller
(A or B) is used.
Note: The following steps must be followed carefully for the upgrade to work
properly. The procedure takes approximately five minutes.
Use the following procedures to perform a shutdown upgrade:
Caution: Before upgrading, verify that the subsystem is in a stable state. This
can be verified by examining the controller Reset button and the adjacent
LEDs. The Reset buttons should be flashing. All adjacent LEDs should be off
(no light). Also, verify that the controller is not reporting a lot of event
information. Issue a SHOW THIS CONTROLLER CLI command from each
involved controllers to ensure controllers are responding to CLI commands as
well. Failure to perform this verification can result in data loss or leave the
controller in an unusable state.
