As you can see, I have added 3x 3TB drives, one each to IDE, SATA, and SCSI. However, when I go into Solaris, the sata drive appears fine. The ide drive is corrupted. The SCSI drive doesn't even show up.

I need to add 8 (preexisting) drives here so that I can migrate the data off it. How do I do it?

Questions

1. Why is the IDE drive showing up at 746.51GB?
2. Where is the SCSI drive?
3. What is the right driver to use for SCSI on solaris?
4. If you noticed "hostpci0: 05:04.0" in /etc/pve/qemu-server/100.conf above, that's the Silicon Image 3124 SATA adapter via PCIe passthrough. However the device isn't appearing, neither is the 300GB hard drive attached to it.
5. I have 8 drives I need to attach to this VM. What is the best way to attach it?
6. Is it possible to add a second SATA controller so that I can qm set XX add -sata6, -sata7, -sata8?
