Are the disks late to be available or do they never appear to the OS? I haven't seen this behavior yet.
rebooting, some drives were missing randomly
...
and without any warning... the connection dropped to 1.5G on sata...
I was troubleshooting for months with 3016 and boughtchenbro sas1 expander (bought $35 at that time).
all gave me headache including chenbro sas1 expander
...
the most important errors were many resets to expander on kernel msgs...
the magic was coming true when move to intel SAS2 expander and SM 3U server case with sas2 expander ( thanks to whomever posted those deals). all my miseries were gone quickly
. I promised to my self.. never and never touch sas1 expander again hahaha.
all drives were 3T. 4T was >$180 at that time
