I just recently upgraded to RHEL V4.5 and to Multipath tools V4.8 but the paths are not being generated. I thought it may be a new restrictions that would be managed via the multipath.conf file; but all tweaks that I've made thus far have not made a difference. Falling back to V4.7 works just fine but I would prefer to stay current with V4.8. Any thoughts? Dmesg does show some errors: SELinux: initialized (dev 0:10, type nfs), uses genfs_contexts device-mapper: dm-multipath: error getting device device-mapper: error adding target to table device-mapper: dm-multipath: error getting device device-mapper: error adding target to table device-mapper: dm-multipath: error getting device device-mapper: error adding target to table device-mapper: dm-multipath: error getting device device-mapper: error adding target to table With v4.7 ...
