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 351, and
Saving Configuration Information in Dual-Redundant
Configurations, page 352, 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 option 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 command:
INITIALIZE DISKnnn SAVE_CONFIGURATION
Saving Subsystem Configuration Information to Multiple Disks
You can save your subsystem configuration information to as many
individual disks as you would like, but you must initialize each using
