I'm using SoftRAID Lite with two raid volumes. After a clean install of 10.13 (due to other problems) I'm always greeted with the message of the sort 'Disk For SoftRAID Volume Disappeared' (or some other of the same kind) for one of the raid sets, and always the same, after wake from sleep. The set seems to function properly though.
I already disabled the option 'Put hard disks to sleep when possible' to no avail.
Any tip?
Thanks, Han

Did you try updating the firmware ?
This only works on Thunderbolt 3 versions of the OWC Thunderbay, though, for when one or two disks eject.
When all the disks eject, that is an Apple triggered issue, we believe, and hard to elminate, although it helps to tighten all cabling and reset NVRAM. (like PRAM)

Thanks for your answer. The RAID sets are internal, in the 4 bays of my Mac Pro 5,1. OS is installed on a SM951 SSD. Before the clean install this problem didn't occur, and it's just one of the two sets, the other one never triggers such an alert.
Would it help when I send a log file?

It avoids my "guessing". ;-)
But in this case, did you try changing the SoftRAID preference for "Mirror timeout"? Make it two minutes.
See if that fixes this.

Alas, that didn't help. And it happens every time when waking from sleep …
Any other suggestion?
Thanks, Han

Inside a Mac Pro 5,1, with the drives in the built in bays, this issue should never happen.
The Mac Pro is a very solid piece of hardware and rarely has any issues until there is a component failing.
Waking from sleep should not make a disk in the Mac Pro not wake up within 30 seconds, or 2 minutes (the max time out value in SoftRAID).
Either a drive is failing, or some other piece of hardware.

I agree ;-)
What component could that be, as it never occurred before the system reinstall …
Something that might point to the culprit: Before reinstalling I made a backup of the system SSD on an external disk. This disk also triggers an alert 'Disk Not Ejected Properly' after Sleep, and that 20 odd times during the night. Other external disks (work files back up, Time Machine back up) don't show any problem of this kind. This behaviour also never happened before the system reinstall.

Maybe it is time to take apart the Mac Pro, put it outside and blow it clean from the exhaust of a vacuum cleaner. Clear out dust from the Motherboards, fans and power supply.
See if that makes any difference.

Hi there, problem solved: the culprit was an older disk I had used as a temporary backup and apparently in some way interfered with the SoftRAID volume. After unmounting this drive the SoftRAID volume has functioned flawlessly.
Thanks for your assistance and time ;-)

Perhaps the SMART test was triggering it.
Glad it worked out.
