When I issue the command:

symcfg list -pool -thin -detail -gb

and get the output:

S Y M M E T R I X   T H I N   P O O L S

Legend:

  (P)ool Type:

S = Snap,  R = Rdfa DSE  T = Thin

  (T)echnology:

S = SATA, F = Fibre Channel, E = Enterprise Flash Drive, M = Mixed, - = N/A

  Dev (E)mulation:

F = FBA, A = AS400, 8 = CKD3380, 9 = CKD3390, - = N/A

  (C)ompression:

E = Enabled, D = Disabled, N = Enabling, S = Disabling, - = N/A

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?
