Removing a Unit

Removing a unit allows you to safely remove drives from a controller in order to move the unit to another controller or to store the drives for safekeeping purposes. This process is sometimes referred to as “array roaming.”

When you remove a unit (in contrast to deleting a unit), information about the unit remains intact on the drives. This allows the drives to be reassembled into a unit again on this controller, or if moved to another controller.

Warning: It is important to remove the unit through software, before removing it physically. Failure to do so could result in a system crash or hang and may even corrupt the data and the unit configuration from being reassembled later.

Note: You can also remove a drive, if you want to force a degrade on a redundant unit, or if you want to remove a drive from the “Available Drives” list so that you can then remove it from the system. For more information, see “Removing a Drive” on page 58.

1Make sure the operating system is not accessing the unit you want to remove.
