Hi,

# ioscan -fnC fc
# swlist -l product | grep -i fc

Also check the below ITRC web link which talks about similar issue.

The complaint about the mismatch of versions is for the data structures. This particular version number is obtained via a runtime ioctl() call. It is not something that will be viewable via a what command.

Many revisions of the driver will have the same version of the data structures. But, when they change, the tools that access and display those structures have to use the same structures as the driver.

This error message comes from a tool which was compiled with one version of the data structure being run on a kernel with a driver compiled with a different version.

A couple easy ways to encounter this would be to copy the tool from a different system; or pull an old version off a backup after the system has been updated. Other ways are certainly possible too.

fcdutil is shipped with the fiber channel driver product. Updating the system (or golden image) with this product will bring the tool/driver back into harmony.
