[PATCHv2 6/6] cciss: Drop obsolete driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The hpsa driver now has support for all boards the cciss driver
used to support, so this patch removes the cciss driver and
make hpsa an alias to cciss.

-Detecting drive failures:
--------------------------
-
-To get the status of logical volumes and to detect physical drive
-failures, you can use the cciss_vol_status program found here:
-http://cciss.sourceforge.net/#cciss_utils
-
-Device Naming:
---------------
-
-If nodes are not already created in the /dev/cciss directory, run as root:
-
-# cd /dev
-# ./MAKEDEV cciss
-
-You need some entries in /dev for the cciss device.  The MAKEDEV script
-can make device nodes for you automatically.  Currently the device setup
-is as follows:
-
-Major numbers:
-	104	cciss0	
-	105	cciss1	
-	106	cciss2
-	105	cciss3
-	108	cciss4
-	109	cciss5
-	110	cciss6
-	111	cciss7
-
-Minor numbers:
-        b7 b6 b5 b4 b3 b2 b1 b0
-        |----+----| |----+----|
-             |           |
-             |           +-------- Partition ID (0=wholedev, 1-15 partition)
-             |
-             +-------------------- Logical Volume number
-
-The device naming scheme is:
-/dev/cciss/c0d0			Controller 0, disk 0, whole device
-/dev/cciss/c0d0p1		Controller 0, disk 0, partition 1
-/dev/cciss/c0d0p2		Controller 0, disk 0, partition 2
-/dev/cciss/c0d0p3		Controller 0, disk 0, partition 3
-
-/dev/cciss/c1d1			Controller 1, disk 1, whole device
-/dev/cciss/c1d1p1		Controller 1, disk 1, partition 1
-/dev/cciss/c1d1p2		Controller 1, disk 1, partition 2
-/dev/cciss/c1d1p3		Controller 1, disk 1, partition 3
-
-CCISS simple mode support
--------------------------
-
-The "cciss_simple_mode=1" boot parameter may be used to prevent the driver
-from putting the controller into "performant" mode. The difference is that
-with simple mode, each command completion requires an interrupt, while with
-"performant mode" (the default, and ordinarily better performing) it is
-possible to have multiple command completions indicated by a single
-interrupt.
-
-SCSI tape drive and medium changer support
-------------------------------------------
-
-SCSI sequential access devices and medium changer devices are supported and 
-appropriate device nodes are automatically created.  (e.g.  
-/dev/st0, /dev/st1, etc.  See the "st" man page for more details.) 
-You must enable "SCSI tape drive support for Smart Array 5xxx" and 
-"SCSI support" in your kernel configuration to be able to use SCSI
-tape drives with your Smart Array 5xxx controller.
-
-Additionally, note that the driver will engage the SCSI core at init
-time if any tape drives or medium changers are detected.  The driver may
-also be directed to dynamically engage the SCSI core via the /proc filesystem
-entry which the "block" side of the driver creates as
-/proc/driver/cciss/cciss* at runtime.  This is best done via a script.
-
-For example:
-
-	for x in /proc/driver/cciss/cciss[0-9]*
-	do
-		echo "engage scsi" > $x
-	done
-
-Once the SCSI core is engaged by the driver, it cannot be disengaged 
-(except by unloading the driver, if it happens to be linked as a module.)
-
-Note also that if no sequential access devices or medium changers are
-detected, the SCSI core will not be engaged by the action of the above
-script.
-
-Hot plug support for SCSI tape drives
--------------------------------------
-
-Hot plugging of SCSI tape drives is supported, with some caveats.
-The cciss driver must be informed that changes to the SCSI bus
-have been made.  This may be done via the /proc filesystem.
-For example:
-
-	echo "rescan" > /proc/scsi/cciss0/1
-
-This causes the driver to query the adapter about changes to the
-physical SCSI buses and/or fibre channel arbitrated loop and the
-driver to make note of any new or removed sequential access devices
-or medium changers.  The driver will output messages indicating what 
-devices have been added or removed and the controller, bus, target and 
-lun used to address the device.  It then notifies the SCSI mid layer
-of these changes.
-
-Note that the naming convention of the /proc filesystem entries 
-contains a number in addition to the driver name.  (E.g. "cciss0" 
-instead of just "cciss" which you might expect.)
-
-Note: ONLY sequential access devices and medium changers are presented 
-as SCSI devices to the SCSI mid layer by the cciss driver.  Specifically, 
-physical SCSI disk drives are NOT presented to the SCSI mid layer.  The 
-physical SCSI disk drives are controlled directly by the array controller 
-hardware and it is important to prevent the kernel from attempting to directly
-access these devices too, as if the array controller were merely a SCSI 
-controller in the same way that we are allowing it to access SCSI tape drives.
-
-SCSI error handling for tape drives and medium changers
--------------------------------------------------------
-
-The linux SCSI mid layer provides an error handling protocol which
-kicks into gear whenever a SCSI command fails to complete within a
-certain amount of time (which can vary depending on the command).
-The cciss driver participates in this protocol to some extent.  The
-normal protocol is a four step process.  First the device is told
-to abort the command.  If that doesn't work, the device is reset.
-If that doesn't work, the SCSI bus is reset.  If that doesn't work
-the host bus adapter is reset.  Because the cciss driver is a block
-driver as well as a SCSI driver and only the tape drives and medium
-changers are presented to the SCSI mid layer, and unlike more 
-straightforward SCSI drivers, disk i/o continues through the block
-side during the SCSI error recovery process, the cciss driver only
-implements the first two of these actions, aborting the command, and
-resetting the device.  Additionally, most tape drives will not oblige 
-in aborting commands, and sometimes it appears they will not even 
-obey a reset command, though in most circumstances they will.  In
-the case that the command cannot be aborted and the device cannot be 
-reset, the device will be set offline.
-
-In the event the error handling code is triggered and a tape drive is
-successfully reset or the tardy command is successfully aborted, the 
-tape drive may still not allow i/o to continue until some command
-is issued which positions the tape to a known position.  Typically you
-must rewind the tape (by issuing "mt -f /dev/st0 rewind" for example)
-before i/o can proceed again to a tape drive which was reset.
-
-There is a cciss_tape_cmds module parameter which can be used to make cciss
-allocate more commands for use by tape drives.  Ordinarily only a few commands
-(6) are allocated for tape drives because tape drives are slow and
-infrequently used and the primary purpose of Smart Array controllers is to
-act as a RAID controller for disk drives, so the vast majority of commands
-are allocated for disk devices.  However, if you have more than a few tape
-drives attached to a smart array, the default number of commands may not be
-enough (for example, if you have 8 tape drives, you could only rewind 6
-at one time with the default number of commands.)  The cciss_tape_cmds module
-parameter allows more commands (up to 16 more) to be allocated for use by
-tape drives.  For example:
-
-        insmod cciss.ko cciss_tape_cmds=16
-
-Or, as a kernel boot parameter passed in via grub:  cciss.cciss_tape_cmds=8

-inside the error handlers, and, the error handlers cannot poll
-for command completion because they might get commands from the
-block half of the driver completing, and not know what to do
