Like again full power off and power on. Or replug the cable.
Yeah, it's been cold-booted and unplugged. It's in a slotted array and
connected to
a HP P440 card in HBA (JBOD) mode, so not much in the way of cables.
What *is* unusual is this disk is SAS the others are SATA.
Although in *theory* these can be mixed, I'm unsure of whether
they can be mixed on the *same card* without encountering
"unexpected behaviour". Like smartmontools seeing the drive
but not the cam subsystem.
It worked well for a time, then the power outage happened, then the
UPS was exhausted, then on cold boot the disk dropped out of the array.
Now it doesn't work for zfs/cam but it does for smartmontools.
next thing to try is see if da7 is seen when booting the latest
snapshot. If not, try booting to a different os
