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

In the past six months, we have primarily developed a server program for video storage. The main function of a program is to store or play back video streams. The program is not large, with less than 5000 rows.
