Since the above step installs several kernel modules into directory

+
+For example, if you want to have dkms support for your SCST rpm install, then

+
+or
+
+ make scst-dkms-rpm

+make rpm-dkms also builds scstadmin packages in addition to the SCST dkms

+SCST Performance
+================
+
+A question that is asked often is how to tune performance. This means how to
+improve the IOPS and/or bandwidth measured at the initiator side. In this
+README it is explained how to optimize storage performance.
+
+Local storage
+-------------
+Start with measuring the performance of the local block device(s). IOPS can be
+measured e.g. as follows:
+
+ fio --ioengine=libaio --rw=randread --ioscheduler=none --numjobs=$(nproc) \
+ --runtime=60 --group_reporting=1 --gtod_reduce=1 --norandommap \
+ --thread --buffered=0 --iodepth=256 --iodepth_batch=128 --bs=4k \
+ --name=bdev --filename=/dev/...
+
+The bandwidth supported by a block device can be measured by increasing the
+block size to a larger value in the above command, e.g. --bs=1M.
+
+Storage network
+---------------
+Start with measuring the network bandwidth using your favorite tool, e.g.
+netperf for non-RDMA networks or ib_write_bw for RDMA networks.
+
+Next, add a nullio LUN to SCST, e.g. by adding the following in /etc/scst.conf:
+
+ HANDLER vdisk_nullio {
+ DEVICE disk09 {
+ blocksize 4096
+ size_mb 256
+ }
+ }
+
+ TARGET_DRIVER ... {
+ TARGET ... {
+ LUN ... disk09
+ }
+ }
+
+After a nullio LUN has been added, verify that this LUN is visible at the
+initiator side. If it is not visible at the initiator side, consider
+rescanning LUNs or disconnecting and reconnecting the initiator system to the
+SCST server.
+
+Once the nullio LUN is visible at the initiator side, measure IOPS and
+bandwidth. The bandwidth should be close to the network bandwidth. When using
+the Linux iSCSI initiator this may require configuring multiple iSCSI sessions
+and activating multipathd on top of the multiple iSCSI sessions. The sequence
+for logging in with iSCSI and activating multiple iSCSI sessions is as follows:
+
+ iscsiadm -m iface -I iface2 -o new
+ iscsiadm -m iface -I iface2 -o update -n iface.initiatorname -v ${iqn2}
+ iscsiadm -m discovery -t st -p ${scst_ip_address}
+ iscsiadm -m discovery -t st -p ${scst_ip_address} -I iface2
+ iscsiadm -m node -p ${scst_ip_address} -l
+ iscsiadm -m node -p ${scst_ip_address} -I iface2 -l
+
+SCST Configuration
+------------------
+If the number of IOPS measured at the initiator side is significantly lower
+than the minimum of the IOPS supported by the local storage and the storage
+network, further tuning is required. Look up in /proc/interrupts which CPU
+cores process the most network and storage interrupts and configure the SCST
+kernel threads such that these run on other CPU cores than those that process
+the most interrupts by configuring the cpu_mask attribute. More information
+about the SCST cpu_mask sysfs attribute is available in the SCST README.

-[SCSI] ibmvstgt: Port from tgt to SCST
-
-The ibmvstgt and libsrp kernel modules as included in the 2.6.37 kernel are
-based on the tgt SCSI target framework. Both kernel modules need the scsi_tgt
-kernel module and the tgtd user space process in order to function
-properly. This patch modifies the ibmvstgt and libsrp kernel modules such that
-both use the SCST storage target framework instead of tgt. As a result,
-neither the scsi_tgt kernel module nor the tgtd user space process are any
-more necessary when using the ibmvstgt driver.
-
-This patch introduces one backwards-incompatible change, namely that the path
-of the ibmvstgt sysfs attributes is modified. This change is unavoidable
-because this patch dissociates ibmvstgt SRP sessions from a SCSI host
-instance. Since the user space STGT driver ibmvio was the only user of
-these attributes, that shouldn't be an issue.
-
-Changes in ibmvstgt compared to kernel 2.6.36:
-- Increased maximum data size for a single SRP command from 128 KB to 64 MB
- such that an initiator is not forced to split large transfers into
- multiple SCSI commands.
-- The maximum RDMA transfer size supported by a single H_COPY_RDMA call is
- queried at driver initialization time from the open firmware tree / larger
- transfers than 128 KB are now supported too.
-- If DMA mapping fails while handling a READ or WRITE command, the offending
- command is retried until the associated data has been transferred instead of
- reporting to the ibmvscsi client that the SCSI command failed.
-- VSCSI command/response queue: one element has been reserved for management
- datagrams since these fall outside the SRP credit mechanism. Added a compile-
- time check whether the size of this queue is a power of two.
-- Fixed a race condition which in theory could have caused the VSCSI receive
- queue to overflow: srp_iu_put() is now invoked before a response is sent back
- to the initiator instead of after.
-- Moved enum iue_flags from libsrp to ibmvstgt because it is ibmvstgt-specific.
-- Removed a variable that was modified but never read from ibmvstgt_rdma().
-- ibmvstgt_probe(): changed the datatype of the variable "dma" from
- unsigned * into const unsigned * such that a cast could be removed.
-- Fixed all compiler and sparse warnings (C=2 CF=-D__CHECK_ENDIAN__).
-
-Changes in libsrp compared to kernel 2.6.36:
-- Renamed vscsis_data_length() into srp_data_length() and exported
- this function.
-- All error messages reported via printk() do now have prefix KERN_ERR.
-- modified srp_target_alloc() and srp_target_free() such that the
- driver-private data reflects whether or not target data has been allocated.
- This change was necessary to avoid that ibmvstgt_remove() triggers a
- NULL-pointer dereference if ibmvstgt_probe() failed.
-- srp_transfer_data(): All three return statements related to DMA mapping
- failure do now return -ENOMEM instead of 0, -EIO and -ENOMEM.
-- srp_direct_data(): Removed the ext_desc argument since not used.
-- srp_direct_data() and srp_indirect_data(): Use DMA_TO/FROM_DEVICE
- instead of DMA_BIDIRECTIONAL for the buffers mapped for transferring data
- via DMA.
-- struct srp_target: eliminated the information unit linked list and also the
- V_FLYING flag since both were duplicating information managed by the SCST
- core.
-- Fixed all compiler and sparse warnings (C=2 CF=-D__CHECK_ENDIAN__).
-
-Tests performed on a backport to kernel version 2.6.18 of this driver with a
-Linux initiator system:
-- Verified that the kernel module ibmvstgt loads and initializes successfully
- and also that the client connects after loading.
-- Verified that all virtual disks configured in scst_vdisk were discovered by
- the client after rescanning the SCSI bus.
-- Verified that after unloading and reloading ibmvstgt and after client
- recovery that the initiator devices were functioning normally.
-- Verified that after a client reboot ibmvscsic reconnected with the target
- and that the target devices were again usable.
-- Performed IO stress testing on the device.
-- Verified that SCSI task abortion works correctly.
-- Performed basic I/O performance testing. With a RAM disk as target linear
- direct I/O throughput was above 2 GB/s and a random I/O test resulted in
- about 30000 IOPS for all block sizes between 512 bytes and 16 KB.
- Both initiator and target were dual core POWER6 LPAR systems.
-
-Note: ibmvstgt is the only user of libsrp.

+Summary of changes between versions 3.6 and 3.7
+-----------------------------------------------
+- The SCST event subsystem works again reliably.
+- Fixed a race condition when replacing a LUN under load.
+- Fixed handling of INQUIRY/SENSE commands that comes with buffer size 0.
+- The behavior of the on_alua_state_change_*() callback functions has been
+ fixed such that these are also invoked for devices that are not in any
+ target.
+- Error handling for iscsi-scst has been improved such that data sending
+ failure no longer crashes the system.
+- An improvement has been added to iscsi-scstd to allow multiple addresses to
+ be specified for the server to listen on.
+- Fixed a hang when unregistering a SCST device due to incorrect device
+ reference counter management in copy manager.
+- Fixed copy manager device update (for auto_cm_assignment=1) such that it no
+ longer corrupts the designator list.
+- Support for scst_tgt_template detect() method has been dropped. This method
+ was declared obsolete in 2015.
+- The scst_user device handler has been made compatible with the
+ qla2x00t-32gbit driver.
+- qla2x00t-32gbit driver: NPIV support has been improved.
+- qla2x00t-32gbit driver: Target mode usage has been simplified by changing
+ the default qlini_mode to exclusive.
+- qla2x00t-32gbit driver: Updated from Linux kernel version v5.15 to v6.1.
+
+The kernel versions supported by this release are:
+* Kernel.org kernel versions v3.10..v6.1.
+* Debian / Ubuntu kernels based on upstream kernel versions v3.10..v6.1.
+* RHEL / CentOS / AlmaLinux 7.x, 8.0..8.7 and 9.0..9.1 kernels.
+* UEK version 4, 5, 6 and 7 kernels.
+
+Summary of changes between versions 3.5 and 3.6
+-----------------------------------------------
+- Made the command processing path slightly faster by removing two atomic
+ instructions from the command processing path.
+- Added support for the READ and WRITE DYN RUNTIME ATTR commands and also
+ for SERVICE ACTION IN(12).
+- An infinite loop in the code that sets CHECK CONDITION has been fixed.
+- A deadlock has been fixed in the code for assigning a device handler to a
+ vdisk.
+- Support for adding a vdisk_blockio device with a non-existent filename has
+ been restored.
+- The async mode of vdisk_fileio has been made compatible with filesystems that
+ use the iomap code, e.g. XFS.
+- A "INFO: rcu_sched self-detected stall" issue has been fixed.
+- Support in the copy manager for auto_cm_assignment=0 has been fixed.
+- Standards-compliance of the copy manager has been improved. Designators with
+ a length above 20 bytes are now rejected instead of being accepted.
+- The copy manager no longer suspends activity when adding a LUN.
+- A bug has been fixed in the vdisk resync_size functionality.
+- The tape device handler now sets 'block_shift' correctly.
+- Improved the code for building a Debian package (dpkg).
+- scst_local: the SCSI host number is now available in sysfs.
+- scst-isert: this driver has been made compatible with
+ CONFIG_HARDENED_USERCOPY.
+- scst-isert: support for RDMA_CV_EVENT_ADDR_CHANGE has been added.
+- scst-isert: a hang in iscsi_release() has been fixed.
+- The top-level Makefile has been modified such that the qla2x00t-32gbit driver
+ is built by default instead of the qla2x00t driver. The qla2x00t driver can
+ be selected by passing QLA_32GBIT=no as argument to make.
+- qla2x00t-32gbit driver: updated from Linux kernel version v5.10 to v5.15.
+- scstadmin: the -force option is now passed to removeGroup().
+- scstadmin: improved performance of the scstadmin function make_path().
+
+The kernel versions supported by this release are:
+* Kernel.org kernel versions v3.10..v5.15.
+* Debian / Ubuntu kernels based on upstream kernel versions v3.10..v5.15.
+* RHEL / CentOS 7.x and 8.0..8.5 kernels.
+* UEK version 6, 7 and 8 kernels.
+
Summary of changes between versions 3.4 and 3.5

* Description:
- * Globally suspends any activity and doesn't return, until there are any
- * active commands (state after SCST_CMD_STATE_INIT). Timeout parameter sets
- * max time this function will wait for suspending or interrupted by a
- * signal with the corresponding error status < 0. If timeout is
- * SCST_SUSPEND_TIMEOUT_UNLIMITED, then it will wait virtually forever.
- * On success returns 0.
+ * Globally suspends SCSI command and SCSI management command processing and
+ * waits until all active commands have finished (state after
+ * SCST_CMD_STATE_INIT). The timeout parameter defines the maximum time this
+ * function will wait until activity has been suspended. If this function is
+ * interrupted by a signal, it returns a negative value. If the timeout value
+ * is SCST_SUSPEND_TIMEOUT_UNLIMITED, then it will wait virtually forever.
+ * Returns 0 upon success.
*
- * New arriving commands stay in the suspended state until
+ * Newly arriving commands remain in the suspended state until
* scst_resume_activity() is called.

-%description
-User space program fileio_tgt uses interface of SCST's scst_user dev
-handler and allows to see how it works in various modes. Fileio_tgt
-provides mostly the same functionality as the kernel space SCST's
-scst_vdisk handler with the only exceptions that it supports O_DIRECT
-mode and doesn't support BLOCKIO one. O_DIRECT mode is basically the
-same as BLOCKIO, but also supports files, so for some loads it could be
-significantly faster, than the regular FILEIO access. All the words
-about BLOCKIO mode from SCST's README file apply to O_DIRECT mode as
-well.

- <h1>IBM Virtual SCSI Target</h1>
- <p>The virtual SCSI (VSCSI) protocol as defined in <a href="http://www.power.org" class="readmore">Power Architecture Standard</a>
- is a protocol that allows one logical partition (LPAR) to access SCSI targets provided by another LPAR.
- The LPAR that provides one or more SCSI targets is called the VIO server or
- VIOS. The ibmvstgt driver is a VIOS driver that makes it possible to access
- exported target devices via the VSCSI protocol.</p>
- <p>This driver is based on ibmvstgt driver, but comparing to the original ibmvstgt has a number of important fixes and improvements.
- The port was made by Bart Van Assche.</p>
- <p>You can download it from the SCST SVN repository. See the download page how to setup access to it.</p>

- <h1>Target driver for QLogic ISP chipsets</h1>
- <p><img src="images/t_unsupported.gif" width="100" height="120" class="float-left" alt="SCST Unsupported">
- This is an SCST driver for ISP QLogic chipsets commonly used in many SCSI and FC host bus adapters.
- It is based on Matthew Jacob's (<a href="http://www.feral.com">http://www.feral.com</a>)
- multiplatform driver for ISP chipsets. Update for SCST was made by Stanislaw Gruszka for Open-E Inc.</p>
-
- <p>The latest release is 1.0.2. It supports kernel versions between 2.6.16 and 2.6.32.</p>
- <p>This driver is obsoleted in favor of qla2x00t.</p>

- <h1>Old target driver for QLogic qla2x00t adapters for 2.4 kernels</h1>
- <p><img src="images/t_unsupported.gif" width="100" height="120" class="float-left" alt="SCST Unsupported">
- Old target driver for QLogic qla2x00t adapters is capable to work on 2.4 kernels.
- It has all required features and looks to be quite stable. It is designed to work in conjunction with the
- initiator driver, which is intended to perform all the initialization and shutdown tasks. In the current release as
- a base for the initiator driver was taken Red Hat's driver from the stock 2.4.20 kernel. Then it was patched to
- enable the target mode and provide all necessary callbacks, and it's still able to work as initiator only. Mode,
- when a host acts as the initiator and the target simultaneously, is also supported. This driver is obsoleted in
- favor of 2.6-based driver.</p>
- <p>The latest version is 0.9.3.4. Requires Linux kernel versions 2.4.20 or higher and SCST version 0.9.3-pre4 or
- higher. If you are lucky, it works also on 2.6 kernels, see README file for details. Tested on i386 only, but
- should work on any other supported by Linux platform.</p>
- <p>Currently it is <strong>not supported</strong> and listed here for historical reasons only.</p>

- <h1>Target drivers for Adaptec 7xxx and QLogic QLA12xx adapters</h1>
- <p><img src="images/t_unsupported.gif" width="100" height="120" class="float-left" alt="SCST Unsupported">
- Target drivers for Adaptec 7xxx and QLogic QLA12xx adapters have been developed by Hu Gang and they available for
- download from <a href="http://bj.soulinfo.com/~hugang/scst/tgt/">http://bj.soulinfo.com/~hugang/scst/tgt/</a>.
- These drivers are not completed, but looks to be a good starting point if you are going to use one of these adapters.
- SCST team don't have the appropriate hardware, therefore have not tested and don't support these drivers.
- Send all questions to <strong>Hu Gang < hugang at soulinfo com ></strong>. If some of these drivers don't compile for
- you, try again with SCST version 0.9.3-pre2.</p><br><br>

- <h1>Patches for UNH-iSCSI Target 1.5.03 and 1.6.00 to SCST</h1>
- <p><img src="images/t_unsupported.gif" width="100" height="120" class="float-left" alt="SCST Unsupported">
- SCST is much more advanced, than the internal mid-level of <a href="http://sourceforge.net/projects/unh-iscsi">
- UNH-iSCSI target driver</a>. With SCST the iSCSI target benefits from all its features and gets ability to use all
- its advantages, like high performance and scalability, SMP support, required SCSI functionality emulation, etc.</p>
-
- <p>Since the interface between SCST and the target drivers is based on work, done by UNH IOL, it was relatively
- simple to update UNH-iSCSI target to work over SCST. Mostly it was "search and replace" job. The built-in
- scsi_target remains available as a compile-time option.</p>
-
- <p>Requires Linux kernel versions 2.4.20 or higher or 2.6.7 or higher and SCST version 0.9.2 or higher.</p>
- <p>Currently it is <strong>not supported</strong> and listed here for historical reasons only.</p>
