The scstadmin manuals still describe the 2.0 parser, a database backend
and SysV-only service integration. They omit current ALUA operations
and call -check_config an offline check even though it reads live sysfs.
Commit 3a8d70b166 ("- Remove old scst_db stuff which no longer
works with even procfs.") removed the database implementation. The
current grammar and apply order live in scstadmin.sysfs/scstadmin,
while SCST/SCST.pm consumes the kernel-provided sysfs metadata.
Document the current commands, quoting, comments, DEVICE references
and systemd environment handling. Keep deprecated-format conversion,
but explain that it reconciles live state. Mark conversion, checking,
examples, installation and service operations with their root, sysfs
and exported-storage effects.
Overview
This is the source code repository of the SCST project. SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes:
- The SCST core in the scst/ subdirectory.
- A tool for loading, saving and modifying the SCST configuration in directory scstadmin/.
- Several SCSI target drivers in the directories iscsi-scst/, qla2x00t-32gbit/, qla2x00t/, srpt/, scst_local/ and fcst/.
- User space programs in the usr/ subdirectory, e.g. fileio_tgt.
- Various documentation in the doc/ subdirectory.
Instructions for building and installing SCST are available in the INSTALL.md file.
QLogic target driver
Two QLogic target drivers are included in the SCST project.
The default driver is located in the qla2x00t-32gbit directory. It is the newer one.
May anyone wish to switch back to the older driver that only supported up to
16 Gb/s adapters, it is located in qla2x00t directory. To make use of the
older driver build scst with environment variable QLA_32GBIT=no set.
