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.
If you just want to rest the disk, you can reset the PHY to which the
disk is attached through sysfs, which is essentially is same as ejecting
and reinserting the disk:
1. Get the PHY index

The standard method to reset the host controller is to call the SCSI
host sysfs reset method, but this does not seem to be supported for
mv_sas - this is no scsi_host_template.host_reset method in the driver.
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.
I'm not sure if this is the correct method.
Thanks,
John
