Linus Torvalds1da177e2005-04-16 15:20:36 -07001Notes for CPQFCTS driver for Compaq Tachyon TS
2Fibre Channel Host Bus Adapter, PCI 64-bit, 66MHz
3for Linux (RH 6.1, 6.2 kernel 2.2.12-32, 2.2.14-5)
4SMP tested
5Tested in single and dual HBA configuration, 32 and 64bit busses,
633 and 66MHz. Only supports FC-AL.
7SEST size 512 Exchanges (simultaneous I/Os) limited by module kmalloc()
8 max of 128k bytes contiguous.
9
10Ver 2.5.4 Oct 03, 2002
11 * fixed memcpy of sense buffer in ioctl to copy the smaller defined size
12Ver 2.5.3 Aug 01, 2002
13 * fix the passthru ioctl to handle the Scsi_Cmnd->request being a pointer
14Ver 2.5.1 Jul 30, 2002
15 * fix ioctl to pay attention to the specified LUN.
16Ver 2.5.0 Nov 29, 2001
17 * eliminated io_request_lock. This change makes the driver specific
18 to the 2.5.x kernels.
19 * silenced excessively noisy printks.
20
21Ver 2.1.2 July 23, 2002
22 * initialize DumCmnd->lun in cpqfcTS_ioctl (used in fcFindLoggedInPorts as LUN index)
23
24Ver 2.1.1 Oct 18, 2001
25 * reinitialize Cmnd->SCp.sent_command (used to identify commands as
26 passthrus) on calling scsi_done, since the scsi mid layer does not
27 use (or reinitialize) this field to prevent subsequent comands from
28 having it set incorrectly.
29
30Ver 2.1.0 Aug 27, 2001
31 * Revise driver to use new kernel 2.4.x PCI DMA API, instead of
32 virt_to_bus(). (enables driver to work w/ ia64 systems with >2Gb RAM.)
33 Rework main scatter-gather code to handle cases where SG element
34 lengths are larger than 0x7FFFF bytes and use as many scatter
35 gather pages as necessary. (Steve Cameron)
36 * Makefile changes to bring cpqfc into line w/ rest of SCSI drivers
37 (thanks to Keith Owens)
38
39Ver 2.0.5 Aug 06, 2001
40 * Reject non-existent luns in the driver rather than letting the
41 hardware do it. (some HW behaves differently than others in this area.)
42 * Changed Makefile to rely on "make dep" instead of explicit dependencies
43 * ifdef'ed out fibre channel analyzer triggering debug code
44 * fixed a jiffies wrapping issue
45
46Ver 2.0.4 Aug 01, 2001
47 * Incorporated fix for target device reset from Steeleye
48 * Fixed passthrough ioctl so it doesn't hang.
49 * Fixed hang in launch_FCworker_thread() that occurred on some machines.
50 * Avoid problem when number of volumes in a single cabinet > 8
51
52Ver 2.0.2 July 23, 2001
53 Changed the semiphore changes so the driver would compile in 2.4.7.
54 This version is for 2.4.7 and beyond.
55
56Ver 2.0.1 May 7, 2001
57 Merged version 1.3.6 fixes into version 2.0.0.
58
59Ver 2.0.0 May 7, 2001
60 Fixed problem so spinlock is being initialized to UNLOCKED.
61 Fixed updated driver so it compiles in the 2.4 tree.
62
63 Ver 1.3.6 Feb 27, 2001
64 Added Target_Device_Reset function for SCSI error handling
65 Fixed problem with not reseting addressing mode after implicit logout
66
67
68Ver 1.3.4 Sep 7, 2000
69 Added Modinfo information
70 Fixed problem with statically linking the driver
71
72Ver 1.3.3, Aug 23, 2000
73 Fixed device/function number in ioctl
74
75Ver 1.3.2, July 27, 2000
76 Add include for Alpha compile on 2.2.14 kernel (cpq*i2c.c)
77 Change logic for different FCP-RSP sense_buffer location for HSG80 target
78 And search for Agilent Tachyon XL2 HBAs (not finished! - in test)

232*************************
233
234If a GBIC of type Short-wave, Long-wave, or Copper is detected, it will
235print out; otherwise, "none" is displayed. If the cabling is correct
236and a loop circuit is completed, you should see "Monitor"; otherwise,
237"LoopFail" (on open circuit) or some LPSM number/state with bit 3 set.
238
239
240ERRATA:
2411. Normally, Linux Scsi queries FC devices with INQUIRY strings. All LUNs
242found according to INQUIRY should get READ commands at sector 0 to find
243partition table, etc. Older kernels only query the first 4 devices. Some
244Linux kernels only look for one LUN per target (i.e. FC device).
245
2462. Physically removing a device, or a malfunctioning system which hides a
247device, leads to a 30-second timeout and subsequent _abort call.
248In some process contexts, this will hang the kernel (crashing the system).
249Single bit errors in frames and virtually all hot plugging events are
250gracefully handled with internal driver timer and Abort processing.
251
2523. Some SCSI drives with error conditions will not handle the 7 second timeout
253in this software driver, leading to infinite retries on timed out SCSI commands.
254The 7 secs balances the need to quickly recover from lost frames (esp. on sequence
255initiatives) and time needed by older/slower/error-state drives in responding.
256This can be easily changed in "Exchanges[].timeOut".
257
2584. Due to the nature of FC soft addressing, there is no assurance that the
259same LUNs (drives) will have the same path (e.g. /dev/sdb1) from one boot to
260next. Dynamic soft address changes (i.e. 24-bit FC port_id) are
261supported during run time (e.g. due to hot plug event) by the use of WWN to
262SCSI Nexus (channel/target/LUN) mapping.
263
2645. Compaq RA4x00 firmware version 2.54 and later supports SSP (Selective
265Storage Presentation), which maps LUNs to a WWN. If RA4x00 firmware prior
2662.54 (e.g. older controller) is used, or the FC HBA is replaced (another WWN
267is used), logical volumes on the RA4x00 will no longer be visible.
