Drop a chunk from a dbspace with onspaces

The following example drops a chunk from dbsp3 on UNIX™. An offset of 300 KB is specified.

onspaces -d dbsp3 -p /dev/raw_dev1 -o 300

You cannot drop the initial chunk of a dbspace with the syntax in the previous example. Instead, you must drop the dbspace. Use the fchunk column of onstat -d to determine which is the initial chunk of a dbspace. For more information about onstat, see information about the onspaces utility in the HCL OneDB™ Administrator's Reference.

For information about dropping a chunk from a dbspace with onspaces, see the HCL OneDB Administrator's Reference.
