我有一个全新的DS5100 SAN连接到多个主机(HS22刀片在BladeCenter H)通过两个独立的织物。开关(用于BladeCenter的Brocade 20p )被正确地划分为区域(BladeCenter中的每一个主机都通过这两种织物看到LUN)。RHEL检测到内置的QLogic QMI2572 4G FC CIO的BladeCenter驱动程序,我可以看到作为dmesg输出的LUN:

scsi 5:0:1:0: Attached scsi generic sg4 type 0 现在的问题是,它们不被认为是SCSI磁盘,而是通用的SCSI设备(/dev/sg{1-4})。显示来自sg_map -i -sd -x'‘的输出:
/dev/sg1 4 0 0 0 0 IBM 1818 FAStT 0730
/dev/sg2 4 0 1 0 0 IBM 1818 FAStT 0730
/dev/sg3 5 0 0 0 0 IBM 1818 FAStT 0730
/dev/sg4 5 0 1 0 0 IBM 1818 FAStT 0730我的基本理解是,即使这是一个多路径设置,我也不必启用它或实际使用MPIO。我尝试了一个快速的解决办法,通过设备映射器多路径,但没有从多路径获得任何输出。sg_map'‘显示这些设备是磁盘(-sd标志),但是LUN没有作为/dev/sd*附加。是否必须手动创建适当的设备节点?我需要使用IBM的RDAC或SDD驱动程序才能看到它们吗?

这很容易;忘记设置LUN和节点之间的映射。
