> Making a Drive Offline or Missing

> If a drive is currently part of a redundant configuration and you want to use it in another configuration, you can use the MegaRAID Storage Manager commands to remove the drive from the first configuration and change the drive state to Unconfigured Good.

> ATTENTION After you perform this procedure, all data on that drive is lost.

> To remove the drive from the configuration without harming the data on the virtual drive, follow these steps:

> 1. | In the MegaRAID Storage Manager window, select Go To > Physical Drive > Make Drive Offline.

> The drive status changes to Offline.

> 2. | Select Go To > Physical Drive > Mark Drive as Missing.

> The drive status changes to Unconfigured Good.

> ATTENTION After you perform this step, the data on this drive is no longer valid.

> 3. | If necessary, create a hot spare drive for the virtual drive from which you have removed the drive (see Adding Hot Spare Drives section.)

> When a hot spare is available, the data on the virtual drive is rebuilt. You can now use the removed drive for another configuration.

> ATTENTION If the MegaRAID Storage Manager software detects that a drive in a virtual drive has failed, it makes the drive offline. If this situation occurs, you must remove the drive and replace it. You cannot make the drive usable for another configuration by using the Mark physical disk as missing command and the Rescan commands.
