Clean up dead network config interface after inactive migration
|
|
|
|
With inactive parition migration, we found there are
|
|
dead network interface asscoiated with the SR_IOV from
|
|
source LPAR that still exist.
|
|
|
|
We need to cleanup the old network interface
|
|
related to this devname from source LPAR. Normally
|
|
in the active parition migration case, this was done
|
|
when HMC issue commands to OS remove the
|
|
VF from hybrid network. Because of the inactive
|
|
migration, the OS was not notified before migration
|
|
that the VF was removed, thus leaves the dead network
|
|
interface belongs on the original MVF on source lpar
|
|
not cleaned up. This cause the confusion of the network
|
|
manager to bring up the bondings with new MVFs at destination
|
|
LPAR.
|
|
|
|
After inactive parition migration the same devname
|
|
could possiblily used at the destination LPAR.
|
|
It can be assigned to a different hybrid
|
|
network (different hcnid). At the OS boot time,
|
|
the same devname but with different hcnid will
|
|
be configured. However the old network work interface
|
|
associated with the same devname from the source LPAR
|
|
has not been cleaned up yet.
|
|
|
|
This patch fix this by during the boot time scan and
|
|
if found an VFs has more than two bonding interfaces,
|
|
or has old VF ifcfg, removed the expired one.
