实现无需重启动Linux系统而识别新添加的LUN

1. Qlogic

 

This utility scans for the newly added LUNs. After adding the new LUNs it is not required to unload/load the QLogic FC driver or reboot the system. To see the newly added LUNs, just run the ql-scan-lun.sh utility.
The simplest way to use this utility is to run
# ./ql-dynamic-tgt-lun-disc.sh
By default the utility would re-scan the QLogic HBAs for new LUNs.

 

2. Emulex

The Emulex Linux LUN/target scan script enables you to dynamically (without a reboot, driver unload/reload, or HBA reset) discover new targets and LUNs (on new or existing targets) that have come online. This feature is supported via standard Linux mechanisms. The script enables you to automatically discover all new devices.
