ZPool seems to be there, but no accessible since upgrade to 11.2

[knucklehead42]

FreeNAS was working fine under 11.1
I set up a small HDD (Seagate 320GB) drive for the OS
Build a zpool of 3 Western Digital 4TB Red NAS drives and created 4 iSCSI "devices" for use by 2 laptops and 2 desktops (1 each)
Worked just fine... I busily stored disk images and some other files on the iSCSI "device" assigned to each desktop/laptop
Last week I see that 11.2 is ready (NOT the beta), so I upgraded the OS (and *NOT* the ZFS)
I let my old age (and assumed level of experience - I've been dealing with mainframes, Unix, and Linux for a long time, but not BSD) get the best of me and did NOT save the system configuration as "suggested" (rather strongly) in the Release Notes before the upgrade to 11.2
Stunned, I don't see my iSCSI block devices anywhere... From the command prompt, I can see the ZPool by name, and it reports SIZE: 10.9T; ALLOC: 4.72T; FREE 6.16T (`zpool list`) but the new GUI can't seem to find the pool...

I really would like to avoid starting from scratch and losing sleep over what I have lost that I can recreate... the image backups are no sweat, but I do NOT remember what I had stored on the iSCSI volumes...

zpool export the pool in the CLI, import it in the GUI.

I took Ericloewe's advice:

zpool export the pool in the CLI, import it in the GUI.

It got me closer (I think) to recovering the iSCSI drives in the pool.
I have added back/imported the four iSCSI drives and the Targets, Extents, and Associated Target fields are populated as they were before.
Even after re-booting the systems that should be attached to these targets/extents, they are not attached or visible to the systems they are supposed to backup.
Clearly I seem to be missing a step (or several)... I'm fairly comfortable with the Linux systems, but the Windows 10 desktop and laptops are more of a mystery to me...
Anyone willing to guide an old mainframe/Unix/Linux guy to reconnecting the appropriate systems to the storage shares?

Presumably it's just a matter of matching the initiators to the correct targets now.
