Description of problem: This patch http://git.kernel.org/linus/5c10e63c943b4c67561ddc6bf61e01d4141f881f was merged in RHEL 5.5. It does not allow devices that are offlined to be onlined. The problem is that in RHEL 5 with qla4xxx and fc drivers using the fc class a device might be offlined due to a transport problem, then later the problem is resolved, but the devices are not usable until a user manually corrects the state. Upstream and in RHEL6, this is not a problem for FC because it will would remove the device when dev_loss_tmo fires and then readd them when the problem is resolved. It is still a problem for qla4xxx, but upstream we are adding dev_loss_tmo functionality. For RHEL 5, we cannot change the default dev_loss_tmo behavior so we should revert the patch.
