Hello,
I've HighPoint RocketRAID 2760A which uses mvsas driver.
When some error happens then disk becomes inaccessible and
to get it usable again currently I know only 2 ways,
either physically pull it out and put back in or reboot whole system.
This is pretty annoying so I want to just reset HBA to simulate that,
but I don't know how to do that.
I have tried:
$ echo 1 > /sys/block/sdf/device/delete
$ echo '- - -' > /sys/class/scsi_host/host0/scan
but it doesn't work as it doesn't detect any new drives.
Some more info see below

1. Get the PHY index

The standard method to reset the host controller is to call the SCSI

I'm not sure if this is the correct method.
Thanks,
