hpsa: add discovery polling for PT RAID devices.

2015-11-09T17:39:27+00:00

There are problems with getting configuration change notification
in pass-through RAID environments.  So, activate flag
h->discovery_polling when one of these devices is detected in
update_scsi_devices.

After discovery_polling is set, execute a report luns from
rescan_controller_worker (every 30 seconds).

If the data from report_luns is different than last
time (binary compare), execute a full rescan via update_scsi_devices.

hpsa: generalize external arrays

2015-11-09T17:39:26+00:00

External array LUNs must use target and lun numbers assigned by the
external array. So the driver must treat these differently from
local LUNs when assigning lun/target.

LUN's 'model' field has been used to detect Lun types that need
special treatment, but the desire is to eliminate the need to reference
specific array models, and support any external array.

Pass-through RAID (PTRAID) luns are not luns of the local controller,
so they are not reported in LUN count of command 'ID controller'.
However, they ARE reported in "Report logical Luns" command.
Local luns are listed first, then PTRAID LUNs.

The number of luns from "Report LUNs" in excess of those reported by
'ID controller' are therefore the PTRAID LUNS.

We can now remove function is_ext_target, and the 'white list'
array of supported model names.

hpsa: change devtype to unsigned

2015-11-09T17:34:19+00:00

This member is used in calls to scsi_device_type.
It should be unsigned since the kernel checks for upper bounds
and it should never be negative.
