Recently I tried to hot-attach a SATA drive to a running system.
Controller is ICH9 in AHCI mode. Physically/electronically everything went
smoothly, the drive spun-up. Then I tried to detach and re-attach all channels
with no devices on them using atacontrol. I did it 3 times to be sure, but no new
disk showed up. Then I finally rebooted, the disk showed up OK.
Question: was hot-attach expected to work? Is there a limitation in hardware or in
our driver?
Note: I attached the drive to a regular SATA port, not eSATA.
