This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. Is there a way to detect if a virtual device is a FCOE device? If so, then it should be fairly easy to do. Thanks & regards, Phil I think the problem is slightly broader than the initial reporting. Any networked storage on a VLAN would have this issue. For example, if iSCSI were run on a VLAN there would be no by-path entry. Sorry to answer your question with another question, but how do I know which path udev is using for its rules in the sysfs tree? With that info I can tell you what the FCoE path looks like. *** Bug 593744 has been marked as a duplicate of this bug. *** *** This bug has been marked as a duplicate of bug 601248 *** |
Description of problem: A restriction was added to the udev rule which generates by-path entries sometime between F11 and F12. The problem is that udev restricts "virtual" devices from having a by-path entry. However, this new restriction does not take networked storage devices running on a VLAN under consideration. fcoe connections are always on VLANs and will always be on "virtual" network devices. Version-Release number of selected component (if applicable): How reproducible: Always. Steps to Reproduce: 1. Use fcoe-utils to connect to a FC SAN using a NIC. * LUNs will be enumerated and by-id and by-uuid entries will be created. * No by-path entries will be created Actual results: Expected results: Additional info: The rule is in: /lib/udev/rules.d/60-persistent-storage.rules ENV{DEVTYPE}=="disk", ENV{ID_PATH}=="", DEVPATH!="*/virtual/*", IMPORT{program}="path_id %p" Either the "virtual" condition needs to be removed or made more elegant.
