I cound start node with use SD from other node,but it had same ESXI managment ip address, after i tried change IP (press F2 and etc) but new(old) IP is unreachable.

I am exhausted figth vs this node. Now i lost FlexFlash from boot order.

Thx Kirk. My support expiried It is the reason why i use forum but not TAC. Now i take SD card from another node and i'm gonna start from it. After i gonna replicate with using FleshFlex
