Notes for CPQFCTS driver for Compaq Tachyon TS
Fibre Channel Host Bus Adapter, PCI 64-bit, 66MHz
for Linux (RH 6.1, 6.2 kernel 2.2.12-32, 2.2.14-5)
SMP tested
Tested in single and dual HBA configuration, 32 and 64bit busses,
33 and 66MHz. Only supports FC-AL.
SEST size 512 Exchanges (simultaneous I/Os) limited by module kmalloc()
max of 128k bytes contiguous.
Ver 2.5.4 Oct 03, 2002
* fixed memcpy of sense buffer in ioctl to copy the smaller defined size
Ver 2.5.3 Aug 01, 2002
* fix the passthru ioctl to handle the Scsi_Cmnd->request being a pointer
Ver 2.5.1 Jul 30, 2002
* fix ioctl to pay attention to the specified LUN.
Ver 2.5.0 Nov 29, 2001
* eliminated io_request_lock. This change makes the driver specific
to the 2.5.x kernels.
* silenced excessively noisy printks.
Ver 2.1.2 July 23, 2002
* initialize DumCmnd->lun in cpqfcTS_ioctl (used in fcFindLoggedInPorts as LUN index)
Ver 2.1.1 Oct 18, 2001
* reinitialize Cmnd->SCp.sent_command (used to identify commands as
passthrus) on calling scsi_done, since the scsi mid layer does not
use (or reinitialize) this field to prevent subsequent comands from
having it set incorrectly.
Ver 2.1.0 Aug 27, 2001
* Revise driver to use new kernel 2.4.x PCI DMA API, instead of
virt_to_bus(). (enables driver to work w/ ia64 systems with >2Gb RAM.)
Rework main scatter-gather code to handle cases where SG element
lengths are larger than 0x7FFFF bytes and use as many scatter
gather pages as necessary. (Steve Cameron)
* Makefile changes to bring cpqfc into line w/ rest of SCSI drivers
(thanks to Keith Owens)
Ver 2.0.5 Aug 06, 2001
* Reject non-existent luns in the driver rather than letting the
hardware do it. (some HW behaves differently than others in this area.)
* Changed Makefile to rely on "make dep" instead of explicit dependencies
* ifdef'ed out fibre channel analyzer triggering debug code
* fixed a jiffies wrapping issue
Ver 2.0.4 Aug 01, 2001
* Incorporated fix for target device reset from Steeleye
* Fixed passthrough ioctl so it doesn't hang.
* Fixed hang in launch_FCworker_thread() that occurred on some machines.
* Avoid problem when number of volumes in a single cabinet > 8
Ver 2.0.2 July 23, 2001
Changed the semiphore changes so the driver would compile in 2.4.7.
This version is for 2.4.7 and beyond.
Ver 2.0.1 May 7, 2001
Merged version 1.3.6 fixes into version 2.0.0.
Ver 2.0.0 May 7, 2001
Fixed problem so spinlock is being initialized to UNLOCKED.
Fixed updated driver so it compiles in the 2.4 tree.
Ver 1.3.6 Feb 27, 2001
Added Target_Device_Reset function for SCSI error handling
Fixed problem with not reseting addressing mode after implicit logout
Ver 1.3.4 Sep 7, 2000
Added Modinfo information
Fixed problem with statically linking the driver
Ver 1.3.3, Aug 23, 2000
Fixed device/function number in ioctl
Ver 1.3.2, July 27, 2000
Add include for Alpha compile on 2.2.14 kernel (cpq*i2c.c)
Change logic for different FCP-RSP sense_buffer location for HSG80 target
And search for Agilent Tachyon XL2 HBAs (not finished! - in test)
Tested with

Gadzoox 3210 (Fabric blade beta)
Vixel 7100 (Fabric beta firmare - known hot plug issues)
using "qa_test" (esp. io_test script) suite modified from Unix tests.
Installation:
make menuconfig
(select SCSI low-level, Compaq FC HBA)
make modules
make modules_install
e.g. insmod -f cpqfc
Due to Fabric/switch delays, driver requires 4 seconds
to initialize. If adapters are found, there will be a entries at
/proc/scsi/cpqfcTS/*

*************************
If a GBIC of type Short-wave, Long-wave, or Copper is detected, it will
print out; otherwise, "none" is displayed. If the cabling is correct
and a loop circuit is completed, you should see "Monitor"; otherwise,
"LoopFail" (on open circuit) or some LPSM number/state with bit 3 set.
ERRATA:
1. Normally, Linux Scsi queries FC devices with INQUIRY strings. All LUNs
found according to INQUIRY should get READ commands at sector 0 to find
partition table, etc. Older kernels only query the first 4 devices. Some
Linux kernels only look for one LUN per target (i.e. FC device).
2. Physically removing a device, or a malfunctioning system which hides a
device, leads to a 30-second timeout and subsequent _abort call.
In some process contexts, this will hang the kernel (crashing the system).
Single bit errors in frames and virtually all hot plugging events are
gracefully handled with internal driver timer and Abort processing.
3. Some SCSI drives with error conditions will not handle the 7 second timeout
in this software driver, leading to infinite retries on timed out SCSI commands.
The 7 secs balances the need to quickly recover from lost frames (esp. on sequence
initiatives) and time needed by older/slower/error-state drives in responding.
This can be easily changed in "Exchanges[].timeOut".
4. Due to the nature of FC soft addressing, there is no assurance that the
same LUNs (drives) will have the same path (e.g. /dev/sdb1) from one boot to
next. Dynamic soft address changes (i.e. 24-bit FC port_id) are
supported during run time (e.g. due to hot plug event) by the use of WWN to
SCSI Nexus (channel/target/LUN) mapping.
5. Compaq RA4x00 firmware version 2.54 and later supports SSP (Selective
Storage Presentation), which maps LUNs to a WWN. If RA4x00 firmware prior
2.54 (e.g. older controller) is used, or the FC HBA is replaced (another WWN
is used), logical volumes on the RA4x00 will no longer be visible.
