I have a very strange issue with a 2540 storage array. I have cam 6.9 running on Solaris and the array is running firmware 7.35. When I register the array it sees it ok however as soon as I finish the registration I lose communication with the array. However I can ping the array and I can also see the controllers and disk's etc within cam. I am also managing a 6540 on the same cam host which I have no issue with.
