Communication error with Virtual Disk Server using Port 0. Retrying.

I have 3 Fujitsu SPARC systems running Solaris 11 and Oracle VM Server.  We had to forcibly restart the systems due to a power incident last week, and now none of my logical domains will start, all presenting the same error at OpenBoot:  "Communication error with Virtual Disk Server using Port 0. Retrying."

I tried removing the vdisk from the ldom, then removing the vdisk from the virtual disk server itself and re-creating both, but this did not help.  I've searched the web for answers, but haven't found a working solution yet.

Some information from the system:
