I'm currently working an issue where we are having CSV problems (STATUS_IO_TIMEOUT, causing all VMs to power off).
As part of my investigation, I noticed the following:
- When the CSV goes to Downlevel, it is showing that it's accessing a SMB CSV path containing a APIPA address:
\Device\SmbCsv\169.254.2.152\GUID$ - That address is bound to a "Tunnel Adapter Local Area Connection" adapter on another host, which is a Failover Cluster Virtual Adapter
- We have IPv6 disabled on all non-loopback interfaces in our Hypervisors by setting the DisabledComponents registry entry to 0xFF
So, the above makes me wonder if:
- Does IPv6 need to be enabled on Hypervisors in a Failover Cluster?
- Why is an APIPA address being used?
