1Notes 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 2.1.1 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. 15 16Ver 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) 24 25Ver 2.0.5 Aug 06, 2001 26 * Reject non-existent luns in the driver rather than letting the 27 hardware do it. (some HW behaves differently than others in this area.) 28 * Changed Makefile to rely on "make dep" instead of explicit dependencies 29 * ifdef'ed out fibre channel analyzer triggering debug code 30 * fixed a jiffies wrapping issue 31 32Ver 2.0.4 Aug 01, 2001 33 * Incorporated fix for target device reset from Steeleye 34 * Fixed passthrough ioctl so it doesn't hang. 35 * Fixed hang in launch_FCworker_thread() that occurred on some machines. 36 * Avoid problem when number of volumes in a single cabinet > 8 37 38Ver 2.0.2 July 23, 2001 39 Changed the semiphore changes so the driver would compile in 2.4.7. 40 This version is for 2.4.7 and beyond. 41 42Ver 2.0.1 May 7, 2001 43 Merged version 1.3.6 fixes into version 2.0.0. 44 45Ver 2.0.0 May 7, 2001 46 Fixed problem so spinlock is being initialized to UNLOCKED. 47 Fixed updated driver so it compiles in the 2.4 tree. 48 49 Ver 1.3.6 Feb 27, 2001 50 Added Target_Device_Reset function for SCSI error handling 51 Fixed problem with not reseting addressing mode after implicit logout 52 53 54Ver 1.3.4 Sep 7, 2000 55 Added Modinfo information 56 Fixed problem with statically linking the driver 57 58Ver 1.3.3, Aug 23, 2000 59 Fixed device/function number in ioctl 60 61Ver 1.3.2, July 27, 2000 62 Add include for Alpha compile on 2.2.14 kernel (cpq*i2c.c) 63 Change logic for different FCP-RSP sense_buffer location for HSG80 target 64 And search for Agilent Tachyon XL2 HBAs (not finished! - in test) 65 66Tested with 67(storage): 68 Compaq RA-4x000, RAID firmware ver 2.40 - 2.54 69 Seagate FC drives model ST39102FC, rev 0006 70 Hitachi DK31CJ-72FC rev J8A8 71 IBM DDYF-T18350R rev F60K 72 Compaq FC-SCSI bridge w/ DLT 35/70 Gb DLT (tape) 73(servers): 74 Compaq PL-1850R 75 Compaq PL-6500 Xeon (400MHz) 76 Compaq PL-8500 (500MHz, 66MHz, 64bit PCI) 77 Compaq Alpha DS20 (RH 6.1) 78(hubs): 79 Vixel Rapport 1000 (7-port "dumb") 80 Gadzoox Gibralter (12-port "dumb") 81 Gadzoox Capellix 2000, 3000 82(switches): 83 Brocade 2010, 2400, 2800, rev 2.0.3a (& later) 84 Gadzoox 3210 (Fabric blade beta) 85 Vixel 7100 (Fabric beta firmare - known hot plug issues) 86using "qa_test" (esp. io_test script) suite modified from Unix tests. 87 88Installation: 89copy file cpqfcTS.patch to /usr/src/linux 90patch -p1 < cpqfcTS.patch 91make menuconfig 92 (select SCSI low-level, Compaq FC HBA) 93make dep 94make modules 95make modules_install 96 97e.g. insmod -f cpqfc 98 99Due to Fabric/switch delays, driver requires 4 seconds 100to initialize.

If the cabling is correct 225and a loop circuit is completed, you should see "Monitor"; otherwise, 226"LoopFail" (on open circuit) or some LPSM number/state with bit 3 set. 227 228 229ERRATA: 2301. Normally, Linux Scsi queries FC devices with INQUIRY strings. All LUNs 231found according to INQUIRY should get READ commands at sector 0 to find 232partition table, etc. Older kernels only query the first 4 devices. Some 233Linux kernels only look for one LUN per target (i.e. FC device). 234 2352. Physically removing a device, or a malfunctioning system which hides a 236device, leads to a 30-second timeout and subsequent _abort call. 237In some process contexts, this will hang the kernel (crashing the system). 238Single bit errors in frames and virtually all hot plugging events are 239gracefully handled with internal driver timer and Abort processing. 240 2413. Some SCSI drives with error conditions will not handle the 7 second timeout 242in this software driver, leading to infinite retries on timed out SCSI commands. 243The 7 secs balances the need to quickly recover from lost frames (esp. on sequence 244initiatives) and time needed by older/slower/error-state drives in responding. 245This can be easily changed in "Exchanges[].timeOut". 246 2474. Due to the nature of FC soft addressing, there is no assurance that the 248same LUNs (drives) will have the same path (e.g. /dev/sdb1) from one boot to 249next. Dynamic soft address changes (i.e. 24-bit FC port_id) are 250supported during run time (e.g. due to hot plug event) by the use of WWN to 251SCSI Nexus (channel/target/LUN) mapping. 252 2535. Compaq RA4x00 firmware version 2.54 and later supports SSP (Selective 254Storage Presentation), which maps LUNs to a WWN. If RA4x00 firmware prior 2552.54 (e.g. older controller) is used, or the FC HBA is replaced (another WWN 256is used), logical volumes on the RA4x00 will no longer be visible. 257 258 259Send questions/comments to: 260Amy Vanzant-Hodge (fibrechannel@compaq.com) 261 262
