What does DIA8402C mean?
Is it dangerous?????

Sometims when i did reorg tables , i found that the tablespace which the reorged table in would become full, when the tablespace was full ,i got the 'DIA8402C A disk error has occurred' .
Sometimes I executed a procedure, I could got same error message.
Sometimes I do LOAD,I could got same error message.

OS: linux as 3 core 2.6
HOSTELL 6650 +SAN CX200
DB: DB2 V8 ,FP6, the tablespace containers is raw device.

I have seen during the reorganization the demand for tablespace increases 1.5-2 times the size of the table . you can use another tablespace during the reorg command.
