Unexpected Shutdown when initializing iSCSI Volume

[To-M]

Use the Write Back feature first.

[nsc]

Write Back is my current config (the one with shutdown...)

May be i could "stress" my second DSS to be sure that is a problem hardware first ?

And to remember, i got a shutdown when applying update 3511, i can suppose that while copying to USB Stick to intern USB the RAID Unit is not used...

[To-M]

When updating with DSS 3511 the system is down so there is no effect on the RAID controller on on the USB DOM.

[nsc]

I got the same shutdown, at 92% of copy, shutdown...

So i could suppose that i have another problem right ?

After this shutdown i made a 4 hours Memtest without any errors...

I could contact my vendor for garanty, but first i need to know which part of the server is deffective...

[To-M]

Did you test with a smaller size, maybe 100GB to see if it crashed again?

[nsc]

After the crash in init volume lv000 : (lv000 1.5 To, lv001 1.4To, lv002 70GB) we restart server and it finish the init without any other trouble.

I removed everything and restart with 10 volumes of 100GB, we'll see.

[nsc]

OK shutdown on lv0006 Ã* 45%...
