[OmniOS-discuss] Slow Drive Detection and boot-archive

[Michael Talbott]

After some more trial and error, disabling/enabling multipath did not help.

But after a little googling, I ran across this: https://syneto.eu/knowledgebase/cannot-use-some-models-of-enterprise-wd-or-seagate-disks/
I guess these guys use the Illumos kernel too and it became obvious I didn't use the right syntax in sd.conf with your previous suggestion.

so I added 
sd-config-list= "WD      WD4001FYYG","power-condition:false";
to /kernel/drv/sd.conf

and it seems to have cut my cold boot time in half :) Still, 4-5 seconds per drive seems pretty high for device detection, but it a vast improvement from than 8-9 seconds per drive.
