How > can I find out the cause of this problem? There is no "problem", per se. That messages means that the OSA detected an unplugged cable or a "dark" switch port. Think of it as "loss of carrier signal." You will see this when someone reboots the switch. You didn't say anything about what release of VM you are running. In early 2010, APAR PK92409 changed the behavior of the LCS device driver so that in addition to the message above, you also get a message telling you that the adapter will be restarted when an "adapter-initiated START LAN" is received. I.e., the carrier signal is heard.
