Add SSD as Cache to Existing Volume
Im wondering if it is possible to add an SSD drive as L2ARC to an existing zpool/volume.
I came across this command but not sure if its what i need to do or if its going to effect the existing volume
"zpool add tank cache c0t5d0 c0t6d0"
Thanks in advance for your assistance

Yes, there is no problem with adding a cache device. It will not affect the volume (at least not in a bad way). Not sure why you cut&pasted that specific command line, but if you are adding device c0t3d0 (for example) as an l2arc device, you do 'zpool add tank c0t3d0'.
