Good day (morning, everning or night

).
I have a problem: system table (database sysmaster table syschuncks) have a wrong record about bad chunk.
This chunk have a PD state (primary down), and he can`t return to PO state (primary on-line - 'onspaces -s MyDataBase -p PathToChunk -o 0 -O' returned 'Bad Parimary Chunk'), and i can`t remove this chunk with 'onspaces -d MyDataBase -p PathToChunk -o 0' function (returned "Bad Primary Chunk").
This chunk at 'onstat -d' have 0% free space, but in syschunk table record of it and at 'oncheck -
pr' have only 3 page (6K) busy.
Question: Where i can find instrument for editing syschunk table records or where i can correct to IDS must do it?
Please, answer this question, the server is stay 3 day, i`m nearly panic...
