ZFS Pool Planning with second hand disks

All of the 3TB and 4TB drives passed SMART long tests except for three of the 3TB ones. What was just seen in one drive (“device not ready”) is now happening in two others, and it appears that they are just spun down. I tried a few commands to try to force them to spin up but no luck so far, but I don’t think they are dead yet. Any ideas to get them spinning again are appreciated.

Regarding the concern about mixing SATA/SAS drives, all my SAS drives are attached via the HBA while the SATAs are connected directly to the mobo. The X9SRL-F has 7 more SATA connectors that I can migrate to over time as the SAS drives get replaced.
