I have 4 seagate ST32000542AS drives connected to my SuperMicro SASLP-MV8
controller configured in a Window 2008R2 Raid 5 volume. I've been having
issues with the drives "unplugging" and have read that this is common for
these drives because ERC is disabled. I installed the latest windows
binaries of smartmontools and can find my drives, but when I issue the
setctl -l scterc /dev/sde command I get the following error:
"Error Write SCT Error Recovery Control Command failed: Function not
Warning: device does not support SCT (Get) Error Recovery Control command"
So after many hours of frustration I think I've finally solved my problems.
I moved my 4 2TB Seagate LP drives off my SASLP-VM8 controller card and
connected them directly to my motherboard's sata ports. In this
configuration I was able to successfully use the smartmontools to set the
ERC to 7 seconds. I'm wondering if smartmontools currently doesn't have the
capability to issue ACT commands to this controller card, or if there is a
hardware/firmware limitation of the card that caused the ACT commands error
out. Any help would be greatly appreciated, as I would like to add
additional drives to my server using the controller card.
