Hello,

We had a very strange situation with a storage system based on MD3620f and a MD1200 connected on it.

We have installed a second MD1200 to the structure, (connecting it to the first MD1200 that was in the infrastructure) and so far so good. After cabling it the second MD1200 was set as part of Disk Pool but the capacity of the second MD1200 was not shown anywhere. Thinking that we may have a problem with the device that we have newly added, we powered it of. At this moment everything is gone down.

After this move we cant manage the storage from MD Launcher (but we can ping the MNGMT ip's).

Also we can connect via console cable to the storage but everything that we have tried was not working.

What we can see from putty console connection:
