Seeing all targets on fibre channel adapter

I have an rp8420 running 11.11 using the AD193A fibre/ether combo cards. An ioscan reveals all the targets on each interface such as c7t0d0 through c7t15d0 where as the actual disk devices are c7t4d2 and c7t4d3. Ioscan takes about 5 minutes to run also. The LUN's are coming from an XP24000. The following is an output of ioscan -fnCdisk:

Is this an array setting or and OS issue?

Re: Seeing all targets on fibre channel adapter

Hi Bruce!

You might want to check the syslog.log for any errors during the time you are running ioscan, also you want to make sure you are running the latest sw for your cards and last check the advised offered in this link:
