I'm afraid that is correct.
When I issue the command:  symcfg list -pool -thin -detail -gb  and get the output:  ------------------------------------------------------------------------------------------------------ ------------ ------ ------------ ---------- ---------- ---------- ---------- ---- ---- ---- ----------  Legend:   (P)ool Type:   (T)echnology:   Dev (E)mulation:   (C)ompression:  I see a column for 'Comp' and in the legend I see (C)ompression: E=Enabled, D=Disabled, etc... My question is, how do you enable or disable compression for the pool?  Or better yet, can I do it for individual TDEV's?
How do you enable compression
