rn104 constantly dropping connection with lun after upgrade to 6.9.4

Did you just upgrade?  There might be some activity that is still running in the background. 

I will do that asap

I tried to download logs but it keeps timming out. I tried with different browsers.

I am trying to download via RADair. it has been 10min and still sitting at 0%.

I found this in the event viewer of the system that connects to the lun -

RAIDar has responded with unable to complete download.

I have noticed that the act light is blinking rapidly so I unplugged the network to see if it made any difference. after 5 min no change to light.

it seems that the system is busy doing something? I also ran diagnostics in RADar and all was good.

Should I reboot the nas and try to download logs again?

I have no access now to the lun as a connection cannot be established with initiator and the network shares are timming out.

I am wondering if I can down grade the system so that I can at least be able to access the files again?

Can I download the 6.9.4 firmware and reinstall the system?

If so are there special steps to do so?

Thanks
