Start cache independent of array

[-Daedalus]

I'm almost sure this has been brought up before, so sorry if I'm duplicating. Googled and searched, couldn't find it.

 

After a recent upgrade, and some problems, I'm in a situation where, because of a failed HBA, I can't bring enough drives online to start my array. Plenty of SATA connections left for my cache pool and any unassigned devices, but can't start the bulk storage.

 

Even though all my VMs, and most of my Docker containers can start, I can't actually do anything with them, so my server, which hosts lots of game servers via VMs, and Plex an associated applications through Docker can't function.

 

TL;DR - Allow starting of cache and unassigned devices outside of main array?
