Description of problem:
BZ 1418065 describes the problem where, in a RHEV environment, when hosts are upgraded to RHEL 7.3 and VMs access a direct lun configured as virtio-scsi with scsi-passthrough enabled and the lun is accessed via an Emulex FC HBA, the VMs will be paused due to an i/o error.
However, the problem is not in RHEV/VDSM, but in the Emulex driver. The current resolution to the bug is to increase the 'lpfc_sg_seg_cnt' in 'lpfc.conf'.
Is it possible/feasible that VDSM can manage this configuration ?
Version-Release number of selected component (if applicable):
100% with the default 'lpfc_sg_seg_cnt' parameter.
Steps to Reproduce:
Refer to BZ 1418065.
Moving to the Node team, ss the discussed solution should come from the platform and node should respin on top of it.
I hate the idea of owning another platform config file; I hope this can be solved below RHV (in the driver) or above RHV (by a customer deployment script).
# rpm -qa| grep qemu-kvm
RHVH include the correct qemu-kvm-rhev version which already included the fix for bug 1431149.
So the bug is fixed, change bug status to VERIFIED.
