| Target driver for QLogic 2[2-6]xx/8[1-3]xx Fibre Channel cards |
| ============================================================== |
| |
| Version 3.5.0, 21 December 2020 |
| ---------------------------- |
| |
| This is target driver for QLogic 2[2-6]xx/8[1-3]xx Fibre Channel cards. |
| Particularly, this driver supports 16G Hilda QLogic chip based adapters |
| (however, post-Hilda QLogic chips not supported). This driver should |
| also support FCoE, but that has never been verified. It has passed |
| intensive internal SanDisk tests. It is stable and production ready. |
| This driver is in stable maintenance mode in favor of the QLogic git |
| driver, which has support for all the latest QLogic adapters. |
| |
| This driver consists from two parts: the target mode driver itself and |
| the changed initiator driver from Linux kernel, which is, particularly, |
| intended to perform all the initialization and shutdown tasks. The |
| initiator driver was changed to provide the target mode support and all |
| necessary callbacks, but it's still capable to work as initiator only. |
| Mode, when a host acts as the initiator and the target simultaneously, |
| is supported as well. |
| |
| This version is compatible with SCST core version 3.2.0 and higher and |
| Linux kernel 2.6.26 and higher. Sorry, kernels below 2.6.26 are not |
| supported, because it's too hard to backport used initiator driver to |
| older kernels. |
| |
| See also "ToDo" file for list of known issues and unimplemented |
| features. |
| |
| |
| Installation |
| ------------ |
| |
| Only vanilla kernels from kernel.org and RHEL/CentOS 5.2 kernels are |
| supported, but SCST should work on other (vendors') kernels, if you |
| manage to successfully compile it on them. The main problem with |
| vendors' kernels is that they often contain patches, which will appear |
| only in the next version of the vanilla kernel, therefore it's quite |
| hard to track such changes. Thus, if during compilation for some vendor |
| kernel your compiler complains about redefinition of some symbol, you |
| should either switch to vanilla kernel, or add or change as necessary |
| the corresponding to that symbol "#if LINUX_VERSION_CODE" statement. |
| |
| Before installation make sure that the link |
| "/lib/modules/`you_kernel_version`/build" points to the source code for |
| your currently running kernel. |
| |
| If your kernel version is <2.6.28, then you should consider applying |
| kernel patch scst_fc_vport_create.patch from the "kernel" subdirectory. |
| Without it, creating and removing NPIV targets using SCST sysfs |
| interface will be disabled. NOTE: you will still be able to create and |
| remove NPIV targets using the standard Linux interface (i.e. echoing |
| wwpn:wwnn into /sys/class/fc_host/hostX/vport_create and |
| /sys/class/fc_host/hostX/vport_delete). |
| |
| Then you should replace (or link) by the initiator driver from this |
| package "qla2xxx" subdirectory in kernel_source/drivers/scsi/ of the |
| currently running kernel and using your favorite kernel configuration |
| tool enable in the QLogic QLA2XXX Fibre Channel driver target mode |
| support (CONFIG_SCSI_QLA2XXX_TARGET). Then rebuild the kernel and its |
| modules. During this step you will compile the initiator driver. To |
| install it, install the built kernel and its modules. |
| |
| Then edit qla2x00-target/Makefile and set SCST_INC_DIR variable to point |
| to the directory, where SCST's public include files are located. If you |
| install QLA2x00 target driver's source code in the SCST's directory, |
| then SCST_INC_DIR will be set correctly for you. |
| |
| Also you can set SCST_DIR variable to the directory, where SCST was |
| built, but this is optional. If you don't set it or set incorrectly, |
| during the compilation you will get a bunch of harmless warnings like |
| "WARNING: "scst_rx_data" [/XXX/qla2x00tgt.ko] undefined!" |
| |
| To compile the target driver, type 'make' in qla2x00-target/ |
| subdirectory. It will build qla2x00tgt.ko module. |
| |
| To install the target driver, type 'make install' in qla2x00-target/ |
| subdirectory. The target driver will be installed in |
| /lib/modules/`you_kernel_version`/extra. To uninstall it, type 'make |
| uninstall'. |
| |
| |
| Usage |
| ----- |
| |
| After the drivers are loaded and adapters successfully initialized by |
| the initiator driver, including firmware image load, you should |
| configure exported devices using the corresponding interface of SCST |
| core. It is highly recommended to use scstadmin utility for that |
| purpose. |
| |
| Then target mode should be enabled via a sysfs interface on a per card |
| basis, like: |
| |
| echo "1" >/sys/kernel/scst_tgt/targets/qla2x00t/target/enabled |
| |
| See below for full description of the driver's sysfs interface. |
| |
| With the obsolete proc interface you should instead use |
| target_mode_enabled under the appropriate scsi_host entry, like: |
| |
| echo "1" >/sys/class/scsi_host/host0/target_mode_enabled |
| |
| You can find some installation and configuration HOWTOs in |
| http://scst.sourceforge.net/qla2x00t-howto.html and |
| https://forums.openfiler.com/viewtopic.php?id=3422. |
| |
| |
| IMPORTANT USAGE NOTES |
| --------------------- |
| |
| 1. It is strongly recommended to use firmware version 5.x or higher for |
| 24xx/25xx adapters. See |
| http://sourceforge.net/mailarchive/forum.php?thread_name=4B4CD39F.6020401%40vlnb.net&forum_name=scst-devel |
| for more details why. Recent report also suggest that openSUSE ships FW |
| 8.6.0 that leads to severe "scst: TM fn ABORT_TASK/0" errors on the |
| target side, but using the latest 8.7.0 firmware from QLogic works well. |
| |
| 2. If you reload qla2x00tgt module, you should also reload qla2xxx |
| module, otherwise your initiators could not see the target, when it is |
| enabled after qla2x00tgt module load. |
| |
| 3. You need to issue LIP after you enabled a target, if you enabled it |
| after one or more its initiators already started. |
| |
| |
| Initiator and target modes |
| -------------------------- |
| |
| When qla2xxx compiled with CONFIG_SCSI_QLA2XXX_TARGET enabled, it has |
| parameter "qlini_mode", which determines when initiator mode will be |
| enabled. Possible values: |
| |
| - "exclusive" (default) - initiator mode will be enabled on load, |
| disabled on enabling target mode and then on disabling target mode |
| enabled back. |
| |
| - "disabled" - initiator mode will never be enabled. |
| |
| - "enabled" - initiator mode will always stay enabled. |
| |
| Usage of mode "disabled" is recommended, if you have incorrectly |
| functioning your target's initiators, which if once seen a port in |
| initiator mode, later refuse to see it as a target. |
| |
| Use mode "enabled" if you need your QLA adapters to work in both |
| initiator and target modes at the same time. |
| |
| You can always see which modes are currently active in active_mode sysfs |
| attribute. |
| |
| In all the modes you can at any time use sysfs attribute |
| ini_mode_force_reverse to force enable or disable initiator mode on any |
| particular port. Setting this attribute to 1 will reverse current status |
| of the initiator mode from enabled to disabled and vice versa. |
| |
| |
| Explicit confirmation |
| --------------------- |
| |
| This option should (actually, almost always must) be enabled by echoing |
| "1" in /sys/kernel/scst_tgt/targets/qla2x00t/target/host/explicit_conform_enabled, |
| if a target card exports at least one stateful SCSI device, like tape, |
| and class 2 isn't used, otherwise link-level errors could lead to loss |
| of the target/initiator state synchronization. Also check if initiator |
| supports this feature, it is reported in the kernel logs ("confirmed |
| completion supported" or not). No major performance degradation was |
| noticed, if it is enabled. Supported only for 23xx+. Disabled by |
| default. |
| |
| For NPIV targets this option is set on their parent targets and shared |
| among all NPIV targets on this hardware target. |
| |
| |
| Class 2 |
| ------- |
| |
| Class 2 is the close equivalent of TCP in the network world. If you |
| enable it, all the Fibre Channel packets will be acknowledged. By |
| default, class 3 is used, which is UDP-like. Enable class 2 by echoing |
| "1" in /sys/kernel/scst_tgt/targets/qla2x00t/target/host/class2_enabled. |
| This option needs a special firmware with class 2 support. Disabled by |
| default. |
| |
| |
| N_Port ID Virtualization |
| ------------------------ |
| |
| Unfortunately, due to severe problems in the original qla2xxx driver, |
| NPIV in this version is not supported. If you need NPIV, you can use |
| previous version 2.1 of this driver. |
| |
| |
| N_Port ID Virtualization (NPIV) is a Fibre Channel facility allowing |
| multiple N_Port IDs to share a single physical N_Port. NPIV is fully |
| supported by this driver. You must have 24xx+ ISPs with NPIV-supporting |
| and NPIV-switches switch(es) to use this facility. |
| |
| You can add NPIV targets by echoing: |
| |
| add_target target_name node_name=node_name_value; parent_host=parent_host_value |
| |
| in /sys/kernel/scst_tgt/targets/qla2x00t/mgmt. |
| |
| Removing NPIV targets is done by echoing: |
| |
| del_target target_name |
| |
| in/sys/kernel/scst_tgt/targets/qla2x00t/mgmt. |
| |
| Also, you can create and remove NPIV targets using the standard Linux |
| interface (i.e. echoing wwpn:wwnn into /sys/class/fc_host/hostX/vport_create |
| and /sys/class/fc_host/hostX/vport_delete). |
| |
| It is recommended to use scstadmin utility and its config file to |
| configure virtual NPIV targets instead of the above direct interface. |
| |
| |
| Compilation options |
| ------------------- |
| |
| There are the following compilation options, that could be commented |
| in/out in Makefile: |
| |
| - CONFIG_SCST_DEBUG - turns on some debugging code, including some logging. |
| Makes the driver considerably bigger and slower, producing large amount of |
| log data. |
| |
| - CONFIG_SCST_TRACING - turns on ability to log events. Makes the driver |
| considerably bigger and leads to some performance loss. |
| |
| - CONFIG_QLA_TGT_DEBUG_WORK_IN_THREAD - makes SCST process incoming |
| commands from the qla2x00t target driver and call the driver's |
| callbacks in internal SCST threads context instead of SIRQ context, |
| where those commands were received. Useful for debugging and lead to |
| some performance loss. |
| |
| - CONFIG_QLA_TGT_DEBUG_SRR - turns on retransmitting packets (SRR) |
| debugging. In this mode some CTIOs will be "broken" to force the |
| initiator to issue a retransmit request. |
| |
| |
| Sysfs interface |
| --------------- |
| |
| Starting from 2.0.0 this driver has sysfs interface. |
| |
| Root of SCST sysfs interface is /sys/kernel/scst_tgt. Root of this |
| driver is /sys/kernel/scst_tgt/targets/qla2x00t. It has the following |
| entries: |
| |
| - None, one or more subdirectories for targets with name equal to port |
| names of the corresponding targets. |
| |
| - trace_level - allows to enable and disable various tracing |
| facilities. See content of this file for help how to use it. |
| |
| - version - read-only attribute, which allows to see version of |
| this driver and enabled optional features. |
| |
| - mgmt - main management entry, which allows to configure NPIV targets. |
| See content of this file for help how to use it. |
| |
| - hw_target (hardware target only) - read-only attribute with value 1. |
| It allows to distinguish hardware and virtual targets. |
| |
| Each target subdirectory contains the following entries: |
| |
| - host - link pointing on the corresponding scsi_host of the initiator |
| driver |
| |
| - ini_groups - subdirectory defining initiator groups for this target, |
| used to define per-initiator access control. See SCST core README for |
| more details. |
| |
| - luns - subdirectory defining LUNs of this target. See SCST core |
| README for more details. |
| |
| - sessions - subdirectory containing connected to this target sessions. |
| |
| - enabled - using this attribute you can enable or disable target mode |
| of this FC port. It allows to finish configuring it before it starts |
| accepting new connections. 0 by default. |
| |
| - explicit_confirmation - allows to enable explicit confirmations, see |
| above. |
| |
| - rel_tgt_id - allows to read or write SCSI Relative Target Port |
| Identifier attribute. This identifier is used to identify SCSI Target |
| Ports by some SCSI commands, mainly by Persistent Reservations |
| commands. This identifier must be unique among all SCST targets, but |
| for convenience SCST allows disabled targets to have not unique |
| rel_tgt_id. In this case SCST will not allow to enable this target |
| until rel_tgt_id becomes unique. This attribute initialized unique by |
| SCST by default. |
| |
| - node_name (NPIV targets only) - read-only attribute, which allows to see |
| the target World Wide Node Name. |
| |
| - parent_host (NPIV target only) - read-only attribute, which allows to see |
| the parent HBA World Wide Port Name (WWPN). |
| |
| Subdirectory "sessions" contains one subdirectory for each connected |
| session with name equal to port name of the connected initiator. |
| |
| Each session subdirectory contains the following entries: |
| |
| - initiator_name - contains initiator's port name |
| |
| - active_commands - contains number of active, i.e. not yet or being |
| executed, SCSI commands in this session. |
| |
| - commands - contains overall number of SCSI commands in this session. |
| |
| Below is a sample script, which configures 2 virtual disk "disk1" using |
| /disk1 image for usage with 25:00:00:f0:98:87:92:f3 hardware target, and |
| "disk2" using /disk2 image for usage with 50:50:00:00:00:00:00:11 NPIV |
| target. All initiators connected to this targets will see those devices. |

| |
| Below is an advanced sample script, which configures more virtual |
| devices of various types, including virtual CDROM. In this script |
| initiator 25:00:00:f0:99:87:94:a3 will see disk1 and disk2 devices, all |
| other initiators will see read only blockio, nullio and cdrom devices. |

| Performance advices |
| ------------------- |
| |
| 1. If you are going to use your target in an VM environment, for |
| instance as a shared storage with VMware, make sure all your VMs |
| connected to the target via *separate* sessions. You can check it using |
| SCST proc or sysfs interface. You should use available facilities, like |
| NPIV, to make separate sessions for each VM. If you miss it, you can |
| greatly loose performance of parallel access to your target from |
| different VMs. This isn't related to the case if your VMs are using the |
| same shared storage, like with VMFS, for instance. In this case all your |
| VM hosts will be connected to the target via separate sessions, which is |
| enough. |
| |
| 2. See SCST core's README for more advices. Especially pay attention to |
| have io_grouping_type option set correctly. |
