Michael Reed 7ba2db5f38 [SCSI] fusion mpt: fix target missing after resetting external raid
Following a hard reset of a SAS raid, one of the raid targets is occasionally
missing.  I tracked this down to a pretty obscure little bug.

The LSI fusion drivers for SAS and Fibre Channel both use their respective
transport layers.  Those transport layers increment the target number
assigned to new targets.

The routine __scsi_scan_target uses the "this_id" element of the Scsi_Host
structure to avoid scanning the scsi host adapter.  Both fusion drivers set
"this_id" from a value returned in a firmware PortFacts response.  For my
particular test case (SAS) the firmware id assigned to the initiator was
173.  After enough raid resets to cause the raid targets to go and come a
sufficient number of times, the id assigned by the transport to a raid
target would match the id assigned by the host adapter to the "this_id"
field, resulting in that target not being scanned.

Fix by not assigning this_id and not checking it in slave_configure.

Eric Moore cc78d30af0 [SCSI] mpt fusion: fix for mounted raid volume filesytem that goes read-only
If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden  raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume.  In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

This address the issue of VMWare guest OS being remounted as read-only
becuase the underlying device was held busy too long and at the

This patch removes the code that snoops the SAM STATUS on busy, which
would be returning DID_BUS_BUSY, instead we return the status as is.
Retry hanlding seems to be properly handled in scsi_softirq_done,
where a busy sam status would only occurr for the time specified by

It also in turn has mptscsih_resume() honour the return value of
mpt_resume()

in mpt_resume(), of which there appear to be many. But this does
seem to be a good start.

Tim Schmielau cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

mptscsih.c

	when firmware reports target is no longer there, return
        DID_REQUEUE for fc hosts so that i/o doesn't get killed until
        the transport has an opportunity to manage the loss via its
        dev loss timer

	when the "eh_abort" routine is called, check to see if the
        driver has the command or not before looking to see if a reset
        is pending.  James Smart and I talked about this and believe
        that the API for this routine is: if driver doesn't have
        command, return SUCCESS.  This change helps prevent a target
        from being taken offline.  SUCCESS is returned because it's
        likely that the command completed after error recovery timed
        it out but before it could be aborted.

	provide a routine to queue work to newly created workq, and
        use it.

	remove "ioc" from mptscsih_abort() it was only used one time.
	the other references were via hd->ioc, so I just moved it....
	net change in references to ioc via hd->ioc is zero

	move hd->resetPending test and hd->timeouts increment to after
	the test for whether the command to be aborted remains known
	to the driver

	Make certain that the workq exists before queuing work to it.

mptfc.c

	no longer need to lock rport data structures as I was able to
	single thread the code!  I fixed up the debug code to
	eliminate compilation messages due to type mismatch in the
	printk.  Got rid of some no longer needed rport flags.
	Initialize and destroy the workq used for the rescan work.

	simplify the logic regarding the increment of
        fc_rescan_work_count.  use post increment and test for zero
        vs. pre increment and test for one; eliminate work_count
        variable: queue_work can be called with the work_lock held as
        it doesn't sleep

James Bottomley c92f222e1f [SCSI] mptspi: Add transport class Domain Validation
This is the first half of a patch to add the generic domain validation
to mptspi.  It also creates a secondary "virtual" channel for raid
component devices since these are now exported with no_uld_attach.

What Eric and I would have really liked is to export all physical
components on channel 0 and all raid components on channel 1.
Unfortunately, this would result in device renumbering on platforms with
mixed RAID/Physical devices which was considered unacceptable for
userland stability reasons.

Still to be done is to plug back the extra parameter setting and DV
pieces on reset and hotplug.

Moore, Eric Dean 466544d889 [SCSI] fusion SAS support (mptsas driver) updates
Summary of Changes:
* splitting mpt_interrupt per Christophs suggestion
about a month ago
* rename ScsiCfgData to SpiCfgData structure,
then move all the raid related info into
new structure called RaidCfgData.  This is
done because SAS supports RAID, as well as SPI,
so the raid stuff should be seperate.
* incorrect timeout calculation for cntdn
inside WaitForDoorbellAck and WaitForDoortbellInt
* add support for interpreting SAS Log Info
* Increase Event Log Size from 0xA to 0x32
* Fix bug in mptsas/mptfc/mptspi - when controller
has Initiator Mode Disabled, and only running in
TargetMode, the mptctl would panic when loading.
The fix is to return 0, instead of -ENODEV, in
SCSI LLD respective probe routines
* Fix bug in mptlan.c - driver will panic if
there is host reset, due to dev being set to
zero in mpt_lan_ioc_reset
* Fix's for SPI - Echo Buffer
* Several fix's in mptscsih_io_done - FCP Response
info, RESIDUAL_MISMATCH, Data Underrun, etc.
* Cleanup Error Handling - EH handlers,
mptscsih_flush_cmds, and zeroing out ScsiLookup
from mptscsih_qcmd
* Cleanup asyn event handling from
mptscsih -> mptscsih_event_process.  Also
added support for SAS Persistent Table Full,
an asyn event
