A DB2 database must be up and running.

Only the DB2 instance owner can run Database Dynamic Storage Tiering commands.

Run the db2ed_update command before running any of the Database Dynamic Storage Tiering commands. You should also run the db2ed_update command if any of the database files change.

Because the Database Dynamic Storage Tiering commands retrieve database information from the repository, the repository must be up to date.

Define the LD_LIBRARY_PATH environment variable as follows:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/VRTSdbms3/lib; \
export LD_LIBRARY_PATH

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/VRTSdbms3/lib32: \
/opt/VRTSdbms3/lib; export LD_LIBRARY_PATH

If you are using any of the Database Dynamic Storage Tiering commands in a high availability (HA) environment, the time on each system in the cluster must be synchronized.

Create the volumes that you want to add to the multi-volume file system in the same disk group as the file system volume. As root, use the following command to change the owner of each volume:

# /opt/VRTS/bin/vxedit -g disk_group \
set user=DB2INSTANCE volume

Change the owner of the mount point on which you want to implement Database Dynamic Storage Tiering to the DB2 instance owner.
