Compaq HSZ80 Array Controller ACS Version 8.3 Configuration and CLI Reference Guide
Backing Up Your Subsystem Configuration
Your controller stores information about your subsystem configuration in its
nonvolatile memory. This information could be lost if the controller fails or when you
replace a module in your subsystem.
See “Considerations for Saving the Configuration,” page 3–55, and “Saving
Configuration Information in Dual-Redundant Controller Configurations,” page
3–56, for more information.
You can avoid reconfiguring your subsystem manually by saving configuration
information on one or more of your subsystem disks using the INITIALIZE
SAVE_CONFIGURATION command. The controller updates the configuration
information saved to disk whenever it changes. If the controller fails or you replace a
module, you can easily restore your subsystem configuration from this information on
the disks. Storing the configuration information uses a small amount of space on each
device.
You do not need to store the configuration on all devices in the subsystem. You can
use the INITIALIZE command without the SAVE_CONFIGURATION switch for
any devices on which you do not want to save the configuration.
You cannot use the SAVE_CONFIGURATION switch on TRANSPORTABLE disks.
Saving Subsystem Configuration Information
to a Single Disk
You can choose to save your subsystem configuration information on a single disk.
Choose a disk on which to save the information by using the
SAVE_CONFIGURATION switch when you initialize the disk with the INITIALIZE
command. Use the following syntax:
INITIALIZE DISKnnnn
SAVE_CONFIGURATION
