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
