Symptoms

In Exalogic 2.0.6.4.X Virtual racks, issue is seen on 2.0.6.4.X OL6 and OL7 Guest vServers where IB Networks both EoIB and IPoIB stops working. After the vServer restart the networks work fine without issues for sometime. But after sometime we notice that one or more Network bonds on the OL6/OL7 Guest vServers stops working. Issue affects all following Exalogic image OL6 & OL7 Guest vServers and EMOC Control stack vservers.

• 2.0.6.4.0
• 2.0.6.4.190115 - January 2019 PSU
• 2.0.6.4.190716 - July 2019 PSU

Below is what we notice at the time of the issue.

• Affected Network bond (EoIB or IPoIB) itself on the vserver is not pingable from other vservers or from the Dom0 compute nodes in the rack.
• Affected vServer is unable to reach ZFS Storage appliance over IPoIB vserver shared storage network. As a result NFS shares cannot be mounted on affected vServers.
• If EoIB bond is affected on the vServer, we notice that the one or both the slaves disappear for EoIB bond. This can be confirmed by running below commands.
