Storage-300d-PX6 lost data via iSCSI

[maviaelnascimento]

Good day

Staff is already the second time I lose this data, I have this storage connected to a server via iscsi dell but from nowhere he stops running until the machine hangs when I see the iscsi driver is not working when I disconnect and try again it says it needs to format more data are there, at least it says the disc is not empty but asks to format as if the driver was new. The first time as it was formatted at the beginning and he is back to normal but now I can not and we have a big project where we will use it and can not get over that surprise, someone has been there?

Thanks to that can help me.
