Subject: SATA hotplug not detecting new disks
Date: Thu, 25 Jul 2013 16:15:05 -0700 [thread overview]
Message-ID: <51F1B179.4070309@sr71.net> (raw)
I've got a relatively new system that doesn't seem to be able to hotplug
SATA disks. I see the same behavior on 3.10, 3.11-rc2, and Ubuntu's
3.8.0-25-generic. The disks are detected right away on reboots, but
even after poking the /sys/class/scsi_host/host*/scan files, new disks
are never detected. I've disabled link power management.
Am I doing something stupid here? I thought this "just worked" on my
previous hardware.
The motherboard is an Intel DH87RL. The SATA controller is:
