Hi, In testing with dm-rdac, I found that multipathing device cannot be properly craeted. The kernel version is 2.6.27-rc7 (SLES11 beta2 kernel), multipathing tool version is 2.4.8-21.1. Theie is error message "ibdevmapper: ioctl/libdm-iface.c(1691): device-mapper: reload ioctl failed: Invalid argument". Can anyone help? Thanks. ......
