  • Sony LMT-300 Raid

    Hi Everyone. I have an issue that I hope someone can help out with, or point me in a right direction.

    My company inherited a few Sony projectors SRX320 with LMT300 servers in them. Unfortunately, we've had one have some hard drive errors and it's down right now. I was able to swap drives with another dead unit, and the server is showing that it sees all the drives and they are good. However, I only have ~50MB of space on the Raid. After looking at the service manual, I see that there is a Raid rebuild procedure. The problem starts here. I don't have the software to do that. I've reached out to Sony support, but who knows when/if I'll hear back from them. I was wondering if someone here might be able to send me the software and info on running it? I've been working on servers and projectors for the company for almost 18 years now, but never had Sony's so little bit of a learning curve. I'd be grateful if someone could help me out.

    Thanks in advance.

    Hello,

    I was delving into other RAID questions and I saw your old post. If no one ever sorted this out for you, the ~57MB showing up on the RAID means the RAID controller itself has failed. You can rebuild the RAID, it will fail again.
    The software you were looking for is SMS Monitor, if you can find a copy somewhere. I only troubleshoot remotely in a NOC, so I can't help you too much on hardware. We go with a media block replacement with these symptoms though.

      The Sony only showing 50MBs is not necessarily a sign of a dead raid controller, but of an unformatted RAID, which is normal when drives from another LMT300 have been inserted. A full RAID format is necessary, following a procedure of loading the formatter software modules through the web interface. A full reformat will take a very long time. Also, before doing that, the RAID config RAM batteries should be swapped.

        Throw the Sony Projectors out and buy new ones. Sorry to say, that will be the right answer in the long run.

          Hello friends, don't go to the forum for a long time, give me an update on this case. I'm passing after the pandemic and that's why the RAID controller's batteries are exhausted, I managed to get the files and reload the process a thousand times without success, there is a kind of bug in the correct execution of the raid, as far as I could notice it was

          - if the raid appears 57 mb and its battery is still functional, if its disks are still preserved by the raid, run raid-builder 1.0 and wait around 72 hours, if the previous is correct it will return to 1.8tb

          - Somehow I exchange battery trays between damaged servers in one of the opportunities I get an 885 GB raid, although somehow the raid assigns 885 GB to storage / and the remaining space in the LOGS, a bug Apparently, I have a working team for over a year now, with limited space only for 2 or 3 FTR

          - I clarify that both servers lasted for 6 months without batteries, I had supposedly lost the certificate, luckily I had made clones of the SSD of each one, after carrying out the backup I had access to marriage and the system as such

          -the second server still didn't work, one day I simply ran the script and the raid was successful... it's the only thing that if I want to restart it makes the problem start correctly and detect the mediablock, the solution never goes out

          - It is important to check that all disks in your raid 6 are functional, or run a raid formatter in this sense, buy the disks here in my country and only sign the digital firm At the end of the disk code, the system continues to recognize it without problems.


          - This has been working without problems for 2 years now, I only ever delete SONY servers unless they are blocked by greater power

          I'm looking forward to answering any concerns​
