Symptoms:

• Require drive re-initialization

Purpose/Scope:

WARNING, this is a destructive process, DATA WILL BE LOST. You should backup critical data prior to implementing this procedure.

This will restore the drive to initial "NEW DRV" status. This process can be utilized as a last resort troubleshooting technique where you suspect private region corruption.

It can also be used in situations that require a complete array rebuild (re-deployment).

In this case (array rebuild), you may also want to review:

WARNING, this is a destructive process, DATA WILL BE LOST. You should backup critical data prior to implementing this procedure.

All steps in the following procedure MUST be followed.

WARNING: It is highly recommended that a FULL backup of the LD or LD's be taken prior to implementing this procedure.

Example:

To Reset reserved space for all disk(s) associated with LD0, config is a follows:

- From array cli main menu, select "view and edit scsi Drives" ---> select target disk "ID 0" ---> select "disk Reserved space - 256 mb" ---> select "yes" when prompted to "Remove Disk Reserved Space ?". Repeat this step for each drive originally associated with ld0, target id's 0, 1, 2.

- Verify disk(s) now report "Status" of "NEW" (sccli) or "NEW DRV" (array cli)

- The drives are now ready to be configured into an LD

The only known reason to utilize this process is to recover from private region corruption, which can be difficult to diagnose and is considered very rare. Because of the destructive nature of this process, great care is advised to ensure, 1.) you understand the process and 2.) ensure data integrity is maintained (if required).
