Do you have any suggestions on how to provide redundancy?

Are those physical disks or LUNs exported from a storage array?

If adding more disks is possible, then you could create mirrored vdevs, by attaching mirror disks to c3t5000CCA012B3E751d0 and c3t5000CCA012B39541d0. See manual for zpool attach command.

Why not just wipe out the zpool mirror that I just added and mirror using those? Pretty much out of disks at this point.

The system will only allow you to detach one disk from that pool. If those are all the disks you can use, then there is no way to provide redundancy without destroying the pool and recreating it from scratch. If you will go this way, this command will create mirrored pool:
Code:
zpool create nbuvol mirror c3t5000CCA012B3E751d0 c3t5000CCA012B39541d0 mirror c5t5000CCA012B4325Dd0 c5t5000CCA00AC56225d0

You should tell the disks capacity and what is the intended usage of the pool.

Bartus suggestion will provide the best performance while a raidz will give you 50% more storage. Both will sustain a full disk failure.
