■ The SCSI_FAIRNESS, SMART_ERROR_EJECT and DEFAULT_ACCESS_MASK
are cleared in both the downgrade cases.
■ If you are downgrading ACS V8.8-x, and pre-existing patches from V8.6 or
V8.7 remain in controller memory, the system downgrades your system to the
highest patch level that was previously installed.
Running the downgrade program
Perform the following procedure to downgrade ACS V8.8- x to V8.7-1 or V8.6-1:
1. Begin the downgrade by entering the following command from a CLI prompt:
TOP> RUN DWNGRD
Figure 103 shows the Downgrade Program Invoked screen.
Figure 103: Invoking the downgrade program
This is the first point where you can exit the program without making any
changes to the controller configuration. The program continues only if you
answer Y(es) to this prompt.
All other responses are assumed to be N(o), and
the program exits.
2. Enter Y(es) to continue with the downgrade. Otherwise, enter N(o) to
terminate the downgrade. After Y(es) is entered, the system requests which
downgrade you want to complete.
3. Enter A or B to downgrade to ACS V8.7-1 or V8.6-1.
Downgrade Program Invoked.
This program downgrades ACS version 8.8 to either ACS version 8.7-1 or ACS
version 8.6-1.
CAUTION: Dismount all units before initiating this procedure.
CAUTION: If you are operating subsystem controllers in a dual-redundant
configuration, you must downgrade both controllers to the same ACS version
BEFORE restarting the controllers.
Are you sure that you want to run this downgrade procedure (Y/[N])? y
