If the Database Dynamic Storage Tiering commands fail as in the following example, review the tsdb_debug.log.

The tsdb_debug.log is located at:

/var/vx/vxdba/logs/tsdb_debug.log

For example, when the following message appears after issuing a dbdst_addvol command review the tsdb_debug.log:

$ /opt/VRTS/bin/dbdst_addvol -S BLM21 -M /dev/vx/dsk/nobody_data1/\
data1vol -v new_vol1:fast_storage,new_vol2:slow_storage,new_vol3:slow_storage

SFORA dbdst_addvol ERROR V-81-6222 Could not add volume new_vol1 to vset

The tsdb_debug.log file contains information that resembles the following:
