There is a server 360 6
On it to be twisted
There are two spot-checks
1+0 72 (2 )
1+0 300 (2)
After connection attempt of a shelf spot-check floated
In adjustment on the server spot-check is visible, and all works perfectly, but  300 disk does not see generally
There is an idea to delete spot-check on 300, and then , the question, the data will be lost in that case?
Or what else there are variants?
