help can't create cache pool??

[tiwing]

I'm sure it's something silly that I'm doing wrong. I've got one 250GB SSD assigned as cache right now. I've stopped the array, and looking for where to add my second 250GB SSD to the cache. I've been all over the web GUI - assume it should be in MAIN but all I have is a dropdown under cache for 1 device. If i remove the cache drive, the drop down changes to none or 1.

 

version 6.1.9.

 

Do I have to specify a cache pool somewhere else first? Is there a plugin that I need? I have a cache only share on the drive now for my VMs, do I need to empty the drive first, remove the share, then add more drives? I thought i read somewhere that you could just add more drives and data would be there.

 

Thanks

Reduce the number of available array slots.
