Resetting a Storage Subsystem Configuration
Related Topics
The Reset Storage Subsystem Configuration option lets you delete the logical drive configuration set at the factory before manually or automatically configuring the storage subsystem. This option also lets you correct configuration errors that cannot be corrected using any other method.
Caution: All data currently stored on the storage subsystem will be lost when you use this option. Do not attempt this operation unless all data on the storage subsystem has been backed up to tape or to another storage subsystem.
Important: Resetting the storage subsystem configuration will cause the following to occur:
- All logical drives and arrays will be deleted.
- The user-supplied name will be deleted.
- If you have password protected your storage subsystem for destructive operations, that password protection will be lost.
- The controller pair will be set to active/passive mode.
Important: The following information must be followed after resetting the storage subsystem configuration. Read this information before proceeding:
- You must change both controllers to Active/Active after a reset if Auto-Logical Drive Transfer (ADT) is enabled. (In the Subsystem Management Window, select Storage Subsystem >> Profile to see if ADT is enabled.)
- If communication with your storage subsystem is through a host-agent and you changed any default LUN assignments for an Access Logical Drive, then those LUN assignments return to their default settings (typically LUN 7 or 31). Because the LUN assignments change, the storage subsystem is unresponsive to any hosts running the Host-Agent software (if they are using the changed LUN assignments).
To reestablish a connection to the storage subsystem, find a responsive management path (for example, one that can still "see" the storage subsystem) and change the LUN assignments back; then reboot the host. If there is no responsive management path, you must reboot the host so the host-agent recognizes the default LUN assignment for the Access Logical Drive.

You don't want to delete the storage subsystem configuration
|
Select Cancel.
Result: You are returned to the Subsystem Management Window.
|
You are absolutely sure you want to delete your entire storage subsystem configuration
|
Type the word "yes" into the dialog box and select OK.
Result:
- The current configuration is deleted, destroying any existing data on the storage subsystem.
- A controller-defined configuration is applied (which may include a default logical drive). All other drives are unassigned.
- The Logical and Physical Views are updated to reflect the new configuration.
