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
$ lspci -vv
