Release Notes
AA–R1ZZE − TE Page 27
5.8.1.2.2 Controller Not Factory Initialized (No Configuration
Data)
With this situation, the new controller does not search the devices in the
subsystem for a saved configuration and the controller is not brought on-line.
The CLI command: SET this_controller INITIAL_CONFIGURATION must be
entered to allow the configuration saved on a storageset to be brought in.
5.8.1.2.3
Controller Has Prior Configuration Data
With this situation, the controller software displays many errors in finding the
disks it assumes is part of the configuration. The CLI command: SET
this_controller INITIAL_CONFIGURATION must be entered to clear the
incorrect configuration from NVMEM and bring in the proper configuration
from the container that has it stored. See the HSZ50 Array Controller HSOF
V5.1 CLI Reference Manual for additional details.
CAUTION
Do not enter any other SET this_controller command other than a
SET this_controller INITIAL_CONFIGURATION. Entering another
type of SET this_controller command may change the configuration
data stored in the controller NVMEM. When this happens, the
software initiates an update of the saved configuration to the
container(s) in which the configuration was saved, thereby
destroying the proper saved configuration
5.8.1.3 Upgrading HSOF Software
When upgrading HSOF software, you can refresh the configuration data on
your storagesets to include the new software revision by issuing the following
command:
SET UNIT XXX WRITE_PROTECT
SET UNIT XXX NOWRITE_PROTECT
[where xxx is any existing unit on the controller]
These commands change the contents of NVMEM, causing the updated
configuration information to be automatically written to the save configuration
area of all containers initialized with this option.
