Storage management allows hot plugging of enclosures. Hot plugging is dened as the adding of a component to a system while the

operating system is still running.

NOTE: This feature requires that the physical devices connected to the controller have the latest rmware. For the latest

supported rmware, contact your service provider.

After you hot plug or hot recongure an enclosure, refresh the left tree to display the change in status and conguration; a system

reboot is not required.

NOTE: Storage Management does not allow hot removal of enclosures. Reboot the system to eect this change in
