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)

*************************
|
||
|
|
|
||
|
|
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.
