I have 5 jbod and i reach each one 2 sas cable with 5 LSI 3008. Last day my cluster imported zfs pool to controller 2. I was have 1 faulted disk in this pool already "sdhr". When the pool imported on controller2 few sec or minute later I lost 1 jbod because mpt3sas_cm2 reset LSI card + expanders. After few sec i was able to use the jbod again.
But why? I was only have 1 faulted disk!. If mpt3 will reset at every import for a faulted disk "which i have 390 disk, i will have 1-2 faulted disk its normal" we have a big problem!
