Use the Reset Storage Subsystem Configuration option to 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.
Important: The following information must be followed after resetting the storage subsystem configuration. Read this information before proceeding.
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 detect 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.
Procedure
1
From the Subsystem Management Window, select either the Storage Subsystem >> Configuration >> Reset Configuration pull-down menu option, or Configuration >> Reset from the right-mouse pop-up menu.
Result: The Reset Configuration dialog is displayed.
2
If...
Then...
You do not want to delete the storage subsystem configuration
Select Cancel.
Result: The Subsystem Management Window is displayed.
You are absolutely sure you want to delete your entire storage subsystem configuration
Type the word Yes into the dialog 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 panes are updated to reflect the new configuration.
