存储分配LUN

Linux主机识别新盘

首先确定物理机的HBA卡的编号

执行下一步

echo"1">/sys/class/fc_host/host？

/issue_lip

？

为系统内部显示的编号，每个都执行一次

接下来执行

echo"---">/sys/class/scsi_host/host？

/scan

？

为上面的HBA卡编号一样，有几个执行几次

最后

fdisk–l

---------------------------------------------------------------------------------------

echo"---">/sys/class/scsi_host/host0/scan

echo"---">/sys/class/scsi_host/host1/scan

echo"---">/sys/class/scsi_host/host2/scan
