1 Notes for CPQFCTS driver for Compaq Tachyon TS
2 Fibre Channel Host Bus Adapter, PCI 64-bit, 66MHz
3 for Linux (RH 6.1, 6.2 kernel 2.2.12-32, 2.2.14-5)
5 Tested in single and dual HBA configuration, 32 and 64bit busses,
6 33 and 66MHz. Only supports FC-AL.
7 SEST size 512 Exchanges (simultaneous I/Os) limited by module kmalloc()
8 max of 128k bytes contiguous.
10 Ver 2.1.1 Oct 18, 2001
11 * reinitialize Cmnd->SCp.sent_command (used to identify commands as
12 passthrus) on calling scsi_done, since the scsi mid layer does not
13 use (or reinitialize) this field to prevent subsequent comands from
14 having it set incorrectly.
16 Ver 2.1.0 Aug 27, 2001
17 * Revise driver to use new kernel 2.4.x PCI DMA API, instead of
18 virt_to_bus(). (enables driver to work w/ ia64 systems with >2Gb RAM.)
19 Rework main scatter-gather code to handle cases where SG element
20 lengths are larger than 0x7FFFF bytes and use as many scatter
21 gather pages as necessary. (Steve Cameron)
22 * Makefile changes to bring cpqfc into line w/ rest of SCSI drivers
23 (thanks to Keith Owens)
25 Ver 2.1.2 Jul 22, 2002
26 * initialize DumCmnd.lun (used as LUN index in fcFindLoggedInPort())
28 Ver 2.0.5 Aug 06, 2001
29 * Reject non-existent luns in the driver rather than letting the
30 hardware do it. (some HW behaves differently than others in this area.)
31 * Changed Makefile to rely on "make dep" instead of explicit dependencies
32 * ifdef'ed out fibre channel analyzer triggering debug code
33 * fixed a jiffies wrapping issue
35 Ver 2.0.4 Aug 01, 2001
36 * Incorporated fix for target device reset from Steeleye
37 * Fixed passthrough ioctl so it doesn't hang.
38 * Fixed hang in launch_FCworker_thread() that occurred on some machines.
39 * Avoid problem when number of volumes in a single cabinet > 8
41 Ver 2.0.2 July 23, 2001
42 Changed the semiphore changes so the driver would compile in 2.4.7.
43 This version is for 2.4.7 and beyond.
46 Merged version 1.3.6 fixes into version 2.0.0.
49 Fixed problem so spinlock is being initialized to UNLOCKED.
50 Fixed updated driver so it compiles in the 2.4 tree.
52 Ver 1.3.6 Feb 27, 2001
53 Added Target_Device_Reset function for SCSI error handling
54 Fixed problem with not reseting addressing mode after implicit logout
58 Added Modinfo information
59 Fixed problem with statically linking the driver
61 Ver 1.3.3, Aug 23, 2000
62 Fixed device/function number in ioctl
64 Ver 1.3.2, July 27, 2000
65 Add include for Alpha compile on 2.2.14 kernel (cpq*i2c.c)
66 Change logic for different FCP-RSP sense_buffer location for HSG80 target
67 And search for Agilent Tachyon XL2 HBAs (not finished! - in test)

224 *************************
226 If a GBIC of type Short-wave, Long-wave, or Copper is detected, it will
227 print out; otherwise, "none" is displayed. If the cabling is correct
228 and a loop circuit is completed, you should see "Monitor"; otherwise,
229 "LoopFail" (on open circuit) or some LPSM number/state with bit 3 set.
233 1. Normally, Linux Scsi queries FC devices with INQUIRY strings. All LUNs
234 found according to INQUIRY should get READ commands at sector 0 to find
235 partition table, etc. Older kernels only query the first 4 devices. Some
236 Linux kernels only look for one LUN per target (i.e. FC device).
238 2. Physically removing a device, or a malfunctioning system which hides a
239 device, leads to a 30-second timeout and subsequent _abort call.
240 In some process contexts, this will hang the kernel (crashing the system).
241 Single bit errors in frames and virtually all hot plugging events are
242 gracefully handled with internal driver timer and Abort processing.
244 3. Some SCSI drives with error conditions will not handle the 7 second timeout
245 in this software driver, leading to infinite retries on timed out SCSI commands.
246 The 7 secs balances the need to quickly recover from lost frames (esp. on sequence
247 initiatives) and time needed by older/slower/error-state drives in responding.
248 This can be easily changed in "Exchanges[].timeOut".
250 4. Due to the nature of FC soft addressing, there is no assurance that the
251 same LUNs (drives) will have the same path (e.g. /dev/sdb1) from one boot to
252 next. Dynamic soft address changes (i.e. 24-bit FC port_id) are
253 supported during run time (e.g. due to hot plug event) by the use of WWN to
254 SCSI Nexus (channel/target/LUN) mapping.
256 5. Compaq RA4x00 firmware version 2.54 and later supports SSP (Selective
257 Storage Presentation), which maps LUNs to a WWN. If RA4x00 firmware prior
258 2.54 (e.g. older controller) is used, or the FC HBA is replaced (another WWN
259 is used), logical volumes on the RA4x00 will no longer be visible.
