About how toad creates an oracle tablespace

Two red hat as 3.0 + Rose ha + Oracle 9i R2 environments have been built in these days, and the data is stored in the EMC array, the array is divided by LVM for multiple database instances. Each instance occupies one PE.
During actual use, I used toad to create a new tablespace for the convenience of the diagram. The database runs normally. However, when the database is switched to another machine by the HA software, it cannot be started immediately. After finding n more information, we always judge that the database service has failed due to file damage or missing. Later, I accidentally found that there was a tablespace file under the DBS directory of Oracle, which corresponds to the new tablespace name I created using toad. It was discovered that the table space was not built on the shared array, it is only created in the local file system. As a result, after the switchover, the database cannot find the tablespace file and cannot run.

It seems that we will try our best to use the built-in Oracle tool to create table space insurance on the server.
