I was running thru' the same issue and good the issue has already been discussed. I will upgrade my SE soon.
In the FAST VP settings, "pool reserved capacity is set to default 10%", and If I would like to reduce the pool reserved capacity to minimum for the SSD pool where I'm not going to bound any tdev, shall I do that in the pool properties ?
So it will keep the PRC of FC pool to default 10% and SSD to 1%. Will it work?
In Unisphere for VMAX, yes -- it's in the pool properties screen.
For SYMCLI, you'd use symconfigure to configure the pool_resv_cap setting. For example --
symconfigure -sid 1234 -cmd "set pool Thin_Pool1, type=thin, pool_resv_cap=1;" commit
Ninja edit: Since you're not binding anything to the EFD pool, your proposed settings (10% global PRC, and 1% EFD pool PRC) are also correct.
