[NPIV] node device vHBA isn't really destroyed
Last modified: 2016-04-26 11:30:13 EDT
Description of problem: node device can't be destroyed. Version-Release number of selected component (if applicable): libvirt-0.8.1-6.el6.x86_64 How reproducible: Always Steps to Reproduce: # virsh nodedev-dumpxml scsi_host7 <device> <name>scsi_host7</name> <parent>computer</parent> <capability type='scsi_host'> <host>7</host> <capability type='fc_host'> <wwnn>2001001b32a9f25b</wwnn> <wwpn>2101001b32a90002</wwpn> </capability> </capability> </device> # virsh nodedev-destroy scsi_host7 Destroyed node device 'scsi_host7' # ls /sys/class/fc_host/ host4 host5 host6 host7 Actual results: device cannot be destroyed. Expected results: device can be destroyed. Additional info: Can workaround by following command. # echo '2101001b32a90002:2001001b32a9f25b' > /sys/class/fc_host/host5/vport_delete # ls /sys/class/fc_host/ host4 host5 host6
This is bad because libvirt reported that the device was successfully destroyed, but it didn't actually go away.
There are really two bugs here. One is the failure to destroy the vHBA, which is a dup of 593995. The destroy operation goes to look up the parent, finds "computer", realizes that it can't issue a destroy operation to it, and fails. I have already submitted a patch upstream to fix this problem. The other bug is that nodeDeviceDestroy does not set its return value correctly on failure. I have a patch which I will be submitting upstream today.
The upstream patch was ack'd and I pushed it earlier today, commit d3e43bad98e3f95408203859bb4165f3b9b10d5b
