* It appears that the udev event for HBA creation arrives before the associated sysfs data is fully populated, resulting in bogus data for the nodedev entry until the entry is refreshed. This problem is particularly troublesome when creating NPIV vHBAs because it results in libvirt failing to find the newly created adapter and waiting for the full timeout period before erroneously failing the create operation. This patch forces an update before any attempt to use any scsi_host nodedev entry. --- src/node_device/node_device_driver.c | 19 +++---------------- 1 files changed, 3 insertions(+), 16 deletions(-)
