Hello, I'm trying to use the multipath software in my project. I downloaded and installed the 2.6.12.rc2-odm1 (I turned on the Multi-Device support/Device Mapper Support and Multipath I/O Support) I also download and install the mutipath-tools 0.4.4. But when I tried [root@dhcp76 multipath-tools-0.4.4]# ./multipath/multipath device mapper prerequisites not met I don't known what's wrong with it. I ran dmsetup [root@dhcp76 multipath-tools-0.4.4]# /sbin/dmsetup targets striped v1.0.2 linear v1.0.1 error v1.0.1 Is that mean I don't have multipath support compiled in the kernel ? Also, I have a generic question regarding to the multipath tool. We ran some virtualization softwares, which generate different UUID (SCSI VPD 83) for the same LUN go through different path, can the multipath software config these two LUNs with difference UUID in a multipath setup ?
