See the commit message in the patch: Before this patch, hotplugging only worked to replace drives (if you tried to plug a drive into a SATA port that no drive was plugged in to at boot, it wouldn't be detected) and you'd have to manually rescan the bus (echo "- - -" > /sys/class/scsi_host/host*/scan) to make plugs/unplugs get detected by the operating system. Now, hotplugging works for all ports (tested and working on Supermicro X11SSH-LN4F) and there's no need to manually rescan (it sometimes takes a few seconds for unplugs to be detected, but plugs are detected instantly). Also submitted upstream as https://review.coreboot.org/c/coreboot/+/91824

Subject: [PATCH] mb/supermicro/x11-lga1151-series: Enable SATA hotplug
|
|
|
|
Before this patch, hotplugging only worked to replace drives (if you
|
|
tried to plug a drive into a SATA port that no drive was plugged in to
|
|
at boot, it wouldn't be detected) and you'd have to manually rescan
|
|
the bus (echo "- - -" > /sys/class/scsi_host/host*/scan) to make
|
|
plugs/unplugs get detected by the operating system.
|
|
|
|
Now, hotplugging works for all ports (tested and working on Supermicro
|
|
X11SSH-LN4F) and there's no need to manually rescan (it sometimes
|
|
takes a few seconds for unplugs to be detected, but plugs are detected
|
|
instantly).
