Recover/Rebuild pool FreeNAS

[TrueMan]

I am trying to recover the pools on a FreeNAS 11.3 server. Unfortunately my project has had to sit idle for the last 12mo while away and I am trying to reeducate myself and pick up where I left off.
I have 3 HHDs in a ZFS pool. I'm not 100% sure but I believe during the last attempt I deleted the pool to recover it.. if this is even possible. Is there a process or utility that can help rebuild recover a pool?
I do not want to loose the data on my server. Let me know what additional information I can/should provide to help in this operation. Any help would be greatly appreciated. Thank you in advance.

I am trying to rebuild pool "T123"

I receive the following error message in 'jails'

You have 2 poolsmarked active for iocage usage.
Run "iocage activate ZPOOL" on the preferred pool.

Do what it says !
You must choose which pool is active for iocage.
Run the command on cli substituting the pool name you select for ZPOOL
