Description of problem: I am unable to get the scan attribute in scsi_host to cause a scan of the SCSI bus to add or remove LUNs. Version-Release number of selected component (if applicable): modinfo() does not report a version for the module fcoe. The kernel is 2.6.32-71.4.1.el6.x86_64. How reproducible: Always Steps to Reproduce: 1.add or remove a LUN presented to the open-fcoe host 2.run Linux command: echo "- - -" > /sys/class/scsi_host/host<n>/scan 3. Actual results: No errors reported. There is nothing in /var/log/messages to indicate a scan of the host bus has been performed. The device that was expected to be removed or added does not occur. Expected results: No errors. The rescan of the host bus should be evident in /var/log/messages and the target LUN added or removed. Additional info:
Tom, please assign as needed, thanks!
The scan attr does not remove devices. It only adds new ones. It also only adds devices on targets/ports that are already discovered. To discover new devices on new targets you have to do a issue_lip first. fcoe.ko does not have a issue_lip function in 6.0, so you can basically just add new devices on existing targets.

This request was erroneously denied for the current release of Red Hat Enterprise Linux. The error has been fixed and this request has been re-proposed for the current release.
Wayne, Based on comment #3, can we close this?
I'll retest this based on comment #3.
Thanks Wayne!
(In reply to comment #3) > fcoe.ko does not have a issue_lip function in 6.0, so you can basically just > add new devices on existing targets. That last part is a mistake on my part. fcoe.ko does support issue_lip, so you can discover new targets.
Wayne, I'll close this for now. Please re-test, and if your testing finds any problems, re-open this. Tom
