scsi: hpsa: Check for vpd support before sending

2016-09-14T18:19:31+00:00

Before using vendor-specific VPD pages for getting raid_level and
device_id, check for page support.  If page isn't supported, don't try
to use it.  Also, pay attention to return status on hpsa_get_device_id.

hpsa: disable report lun data caching

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

When external target arrays are present, disable the firmware's
normal behavior of returning a cached copy of the report lun data,
and force it to collect new data each time we request a report luns.

This is necessary for external arrays, since there may be no
reliable signal from the external array to the smart array when
lun configuration changes, and thus when driver requests
report luns, it may be stale data.

Use diag options to turn off RPL data caching.

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: correct check for non-disk devices

2015-11-09T17:34:20+00:00

The driver is using two MACROs which seemingly are looking in
the wrong location for the device_flags returned from
CISS_REPORT_PHYS. Both MACROs, NON_DISK_PHYS_DEV and
PHYS_IOACCEL, are using the pointer returned from figure_lunaddrbytes
which is the address of the LUN.lunid element in
the extended CISS_REPORT_PHYS.  But the MACROS are using offsets
beyond the range of the element (offset 17 of an 8 byte element).

These MACROs actually are looking at the correct location but
they fail static checker analysis. It also will not work
if any new elements are added to the extended LUN structure.

Change the code to use the structure elements directly
since this MACRO is only used in one location.
