6140 CAM Software Connection Problems
We recently purchased a 6140 array and are currently performing evaluations before putting it into production. The array firmware version is 06.19.25.10. We抳e loaded the CAM software (version 5.1) from the CD that came with the array on 3 management servers. Two are running Solaris 10 and one is running windows. The array has been registered with the CAM interface on each server.
Occasionally we are unable to connect with the array via the web based interface or the CLI. We get messages such as 揅onnection Refused?or 揟he Operation Failed? First impressions lead us to think that the array (controller) may have an issue. We are able to 損ing?the IP addresses of each controller verifying a good connection on the LAN. Since we have more than one management server set up, we decided to try connecting with another server. This usually works.
Thinking that the array (controllers) may have some residual information or an improper logout had occurred, we connected via one of the other servers and issued a reset to each of the controllers. This does not seem to help. The last time we encountered this problem it was necessary to completely uninstall the CAM software and re-install it. This has happened on both platforms. As you can imagine, we抮e not looking forward to doing this every time the CAM software has an 搃ssue?
It appears from our informal testing that the problem lies on the server rather than the array when this happens. A little guidance or access to some documentation that deals with our problem would be greatly appreciated.

I have had sort of the same problem, nut it has always been a problem with the 6140 controllers on an earlier version of firmware. Although I don't know the answer to your problem, it may be worth looking at the Array and seeing of there are any Alarms. If there are any then the description of the Alarms may give you a clue.
I have seen a problem on Solaris 10 and CAMS whereby the webconsole hadn't been started after a reboot and of course pinging the addresses of the 6140 controllers would work anyway. I never tried using the SSCS command when the webconsole wasn't running so I don't know if they are related. I have installed quite a few 6140 arrays but only had comms issues on old firmware.

For those who may be following this thread.
Just prior to upgrading the CAM software on the Sun server that has the connection problems, I verified that we could access the array via the CAM software on the other Sun server and through our Windows machine. This leads me to believe that the array controllers and array firmware were functioning properly.
We upgraded the CAM software (which performs an uninstall first) on the Sun server with the connection issues and was then able to communicate with the array. We have not upgraded firmware on the array of reset the array controllers. Again this has me thinking that the problem we're experiencing is related to something happening locally on the server. I can't help thinking there's a file somewhere that can simply be cleared out when this happens. If I happen to come across any more information on this I'll post it to this thread.
