Reboot is not required for Linux server to load storage

Some Linux database servers use low-end storage. Due to service changes, some Luns are required. Must I restart a Linux server after adding a LUN?

Use the QLogic fc hba lun Scan Utility script to identify newly added Luns without restarting the system. You do not need to re-Load the QLogic FC driver. Scenario: Linux Server + QLogic memory card.

Take the Qla2340 memory card of QLogic as an example. Download the script (by the way, the QLogic fc hba Information Utility on this page is also useful ).
